Cisco CloudCenter Suite: Your Multicloud Management Champion

In a few days, over one hundred million viewers will experience the phenomenon known as the Super Bowl. As fans of championship sporting events like the Super Bowl or, for my friends outside of the US, the World Cup, we expect a gratifying experience during these events and are solely focused on our favorite team’s accomplishments. At this point, we don’t care how many practice sessions and training hours were involved, or how long it took the team to reach this level. Our only expectation is to witness a superb performance culminating in our favorite players lifting the trophy; little do we dwell on the inherent complexity of what it took to get there.

In reality, championship teams prepare for this “trophy lifting” experience for years by developing and executing a framework of specific components: talent (management, players, coaching, supporting staff), teamwork (working together), discipline (execute to the plan), and a little luck.

Now in cloud, the expectations of cloud consumers are similar to those of sports fans. They adopt cloud platforms to exploit their numerous benefits: accelerate innovation, increase scale, or reduce operational expenses. Increasingly they are adopting multiple clouds simultaneously to leverage the unique advantages that each of them has to offer. But the specific use case, whether it’s to manage hybrid cloud workloads or distributed multicloud applications, is just a means to an end for them.

But for organizations, it’s all about taking the championship team’s point of view. Because to truly realize the benefits of a multicloud approach, they need a cloud management platform (i.e. a framework) that works across many clouds, both public and private. One that provides the best finished product, while abstracting the inherent complexities.

The newly announced Cisco CloudCenter Suite does just that, via a single solution that works across multiple clouds, doing what many other tools do separately or only for specific clouds.

Cisco Cloud Center, Cisco Tutorial and Materials, Cisco Learning, Cisco Certifications

Cisco CloudCenter Suite is an integrated set of software modules that accelerates innovation by providing a framework for organizations to design, deploy, and optimize infrastructure and applications across clouds to achieve their cost and compliance objectives. The suite simplifies multicloud management by providing workflow automation, application lifecycle management, cost optimization, governance and policy management across clouds.

Cisco CloudCenter Suite is now a modular, self-managed, Kubernetes-based solution that gives you all the benefits of a microservices application without actually having to manage one. It consists of:

Three modules that work together to simplify multicloud management 

◈ Workload Manager – Multicloud management of infrastructure and applications that helps customers design, deploy, and optimize their on-premises and public cloud environments. Workload manager enables governance policies, aligned with the organization’s objectives, that provide centralized visibility and control to help customers improve their multicloud maturity.

◈ Cost Optimizer – Cost reporting and remediation that analyzes customers’ consumption patterns on-premises and in public clouds and provides visibility into total cloud spend (compute, storage, network, and cloud services). It also identifies cost-optimization strategies to help customers right-size their cloud workload instances by minimizing overprovisioning.

◈ Action Orchestrator – Simplified orchestration and workflow automation that provides seamless integration within the suite and externally through a broad set of adaptors and standardized interfaces. This simplifies business processes, reduces human error, and eliminates repetitive tasks associated with technical integrations and business processes.

◈ Suite Admin – Central administration point for all CloudCenter Suite modules. It provides common services such as managing cloud accounts, multi-tenancy, licensing, monitoring and logging, role-based access control, user authentication, and single sign-on integration.

◈ Suite Installer – A self-deployed, self-managed installer that takes care of the installation process for the Kubernetes-based CloudCenter Suite on any environment (VM, OpenStack, on-premises and in public clouds).

Cisco Cloud Center, Cisco Tutorial and Materials, Cisco Learning, Cisco Certifications

CloudCenter Suite delivers a ubiquitous experience across your multicloud environments, whether on-premises or in the cloud, so that you can focus on developing and deploying applications with speed and scale. At design time, architects can compose the dependencies of their multi-tier applications into an application profile. Designers can leverage numerous out-of-the-box integrations across many Cisco products and other ecosystem solutions to build on the strength of Cisco’s ever-increasing investments in cloud technologies. Consumers can then deploy the profile, devoid of multicloud complexities, using a pre-established governance framework consisting of application and infrastructure policies. Applications are delivered consistently and reliably across private and public clouds in a manner that eases the transition to operations teams. Both consumers and operators can optimize infrastructure and applications anywhere through a recommendation engine that exposes the most economical consumption opportunities.

CloudCenter Suite’s flexible consumption models enable customers to choose the buying option that best suits their organizations’ use case requirements and price points, with three subscription-based license tiers available as self-hosted or SaaS. Small and mid-size enterprises can now take advantage of the same premier multicloud management capabilities enjoyed by large enterprises.

How does CloudCenter Suite deliver “quick wins” for cloud consumers and IT operators? It helps teams:

◈ Focus on accelerating innovation and reducing time to market by delivering applications wherever the cloud strategy dictates.
◈ Capitalize on the unique benefits of each provider by easing the management of multiple clouds.
◈ Reduce total cloud costs without compromising application performance by monitoring private and public cloud usage.
◈ Automate complex business processes to reduce digital waste and precious time and resources.

Championship teams operate best when the unique skills of each team member seamlessly come together to accomplish a common goal. CloudCenter Suite unifies your multicloud experience in the same way—enabling you to secure the best value from the ‘skills’ each cloud provider has to offer.

DevOps with CloudCenter Suite and Kubernetes in a Multicloud Environment – Part 2

This post is the 2nd part our series on DevOps and will focus on a CI/CD demo based on Cisco Multicloud Portfolio. You can find part one here. For our demo environment, we are using resources from 3 Kubernetes clusters, on-premises and in AWS.

Our lab

We have built a simple microservice-based application as shown by the picture below.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification

 The source code of the 5 components is stored in a github repository, where new versions of the application are committed (uploaded) by developers. At each commit, the Jenkins orchestrator gets the source code and compiles it, building the container images ready to deploy the application.

The images are saved in a shared container registry (Harbor, see next picture) where Cisco CloudCenter (or Cisco CloudCenter Suite, as per the official new title) will be able to retrieve them when asked by Jenkins to deploy the application. Based on input parameters provided by Jenkins, Cisco CloudCenter will target the deployment to the most appropriate environment for the current phase of the project.

In our demo lab, the environments are “integration test”, “performance test” and “production”.

They correspond to three different Kubernetes clusters that have been created on-premises (integration and performance test) and in AWS (production).

Each environment has different set of policies, that will be inherited by every application that is deployed there: policies for security, networking, autoscaling, etc.

The 3 Kubernetes clusters mentioned above have been quickly deployed by the Cisco Container Platform (CCP) without having to manually create them on each side.

The value in using CCP here is simple: in few minutes we created and deployed 3 production-ready clusters, fully integrated with networking, storage, security, monitoring and logging without even touching the K8s installer or the underlying infrastructure.

The 2 clusters named “integration test” and “performance test” were created automatically inside VM in a local VMware environment, while the cluster named “production” was created in AWS (CCP uses the API exposed by AWS’s Managed Kubernetes Service (EKS) to do everything automatically, including the integration with AWS’s Identify and Access Management (IAM) for authentication, authorization and access control)

The automated deployments will repeat, in the three environments, in a sequence that tests each version before moving it to the next deployment environment, ensuring the quality of the release. In the real world you might want to run more complex testing activities (such as code quality inspection, security, resiliency etc) than the 2 tests in this example (functional and performance).

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification

Demo flow

◈ The next picture is a sequence diagram showing all the actions that we have automated; we used a color code to represent the phases that are commonly referred to as Continuous Integration (the green part) and Continuous Deployment (the orange part).
CCC stands for Cisco CloudCenter, where K8s dev, test and production represent the 3 Kubernetes clusters mentioned above.

◈ The entire process is completely automated and brings a new version of the application to the production deployment without any human intervention. This complete automation is often referred to as Continuous Deployment and – although very useful and adopted by big players like Facebook (their pipeline is more complex than our simplified demo) – is not very common among the customers I generally meet.

Those that adopted DevOps still prefer to have some human checks in between the activities, so that they feel they have a better control on the process and its quality.

When they have more experience, they will probably be confident enough to delegate every check to the automation tools.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification


The automation is based on Jenkins, an open source orchestrator that benefits from the availability of hundreds of plugins; it can automate almost every component in your IT ecosystem, including Cisco CloudCenter of course.

In the Jenkins dashboard you can build different projects, like in the picture below. A project is a sequence of steps, using plugins to drive activities in the systems you want to automate (e.g. pull the source code from the repository, compile it, build container images, trigger a cloud deployment through Cisco CloudCenter, etc.).

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification

Projects can call other projects, to make your orchestration modular and reusable. In the picture above, the project ‘TheWall’ (that is the name of our demo application) calls the other 5 projects in a sequence, checking that the outcome is positive before calling the next one.

◈ With this we are able to automate the deployments on those 3 Kubernetes clusters and run the functional test and the performance test of the application using an external tool (here we are using another open source product called Apache Jmeter).

◈ The functional test (which happens on the integration test cluster) is a sequence of user transactions, executed by the test tool using a pool of user identities and a pool of input data such as simulated clicks and text inputs, where assertions about the expected result are validated automatically. If the page generated by the application differs from the expected result, an error is logged, and the test can be considered failed. So, the functional test ensures that the application behaves as expected from a functional standpoint (and you can avoid a manual test for user acceptance).
The performance test (which happens on the performance test cluster), executed by the same tool, stresses the application and the infrastructure from a performance standpoint. A large number of concurrent users are simulated by the tool, invoking a sequence of user transactions with random wait time, reproducing a situation similar to the workload in a production environment. Response times are tracked and so are eventual errors, allowing the tool to declare whether the test is successful or not.

Based on the outcome produced by Jmeter, Jenkins will continue with the Continuous Deployment pipeline or abort it, notifying the developers that something went wrong, requiring a correction. In the latter scenario, the CI/CD cycle will start from the beginning: new modified source code modified committed, application built and deployed to the first environment, test executed, application promoted to next environment and tested… until the pipeline is completely executed without any warning or error and the application is released automatically in production.

The next picture shows the execution of the Jenkins pipeline for three different builds of the application. The most recent execution failed because the modification of the source code introduced an error that blocked the build. The other two executions succeeded, as demonstrated by the green color of every step in the pipeline.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification

Jenkins logs all the activities, so that you can check what happened during the automated process.

The next picture shows the output of the sub-project named ‘TheWall_Deploy_Test’, that is the 7th stage in the pipeline in previous picture.

In order for us to ensure that governance policies are applied during deployment (such as access control, reporting, cost control etc), we have inserted CloudCente in the process. Jenkins will use the API exposed by Cisco CloudCenter to deploy the application ‘TheWall’ to the test environment.

Note that the performance test environment needs to be robust enough to sustain the workload of the performance test, whileon the contrary, the functional test can be executed in a smaller cluster with less computing power.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials, Cisco Certification

You don’t have to code the API calls, because Cisco CloudCenter ships a plugin for Jenkins that integrates into its user interface graphically. But if you prefer, Jenkins can run scripts and commands from the CLI for you.

Enter The Cloud Maturity Era (Until The Next One)

Just before the end of the year we announced and made available our latest hybrid solution, a product of collaborating with AWS, the Cisco Hybrid Solution for Kubernetes on AWS (yes there are definitely more words in that title that I can count in one hand).

And at the same AWS re:Invent that we first showcased our solution, AWS announced more than 60 new features and services for their platform; new compute instances, storage and archiving, databases, data lakes, blockchain, ML/AI, serverless, networking and control services.

Amongst many topics at that conference, cost management was especially hot, and validates what we have been hearing from customers a lot lately. So at our equivalent annual European conference, Cisco Live, in Barcelona, we announced our Cisco CloudCenter Suite (including enhanced cost management features) as well as ACI Anywhere, enabling customers to extend their on-premises data center networks directly to pubic clouds.

And what happened in those few short months is just the tip of the iceberg. This amount of innovation coming from the industry is evidence of the industry maturing.

Customers are now evaluating and planning to adopt more advanced solutions between on-premises and public clouds than just IaaS and SaaS, and the industry is responding to this demand with a new generation of offerings.

Scaling up innovation

Is this really new news? What has been the evolution of cloud computing and what does that tell us about the paradigm, the market and its future overall?

Let’s take a step back. In 2012’s Gartner’s Hype Cycle, more mature cloud offerings and concepts PaaS or “cloud-optimized application design” were given 2-5 years for mainstream adoption, as opposed to IaaS or SaaS.

And looking at the date today makes you think they were about right, weren’t they? Score one for Gartner.

Cisco Tutorial and Material, Cisco Study Materials, Cisco Learning, Cisco Cloud

Indeed, we are slowly moving towards the maturity of the “platform” era, where cloud computing is about to become more interesting, honouring its roots to service-oriented architecture moving further away from being just a technical answer to an infrastructure use cases to being more closely aligned to business initiatives.

The result? To better align with business use cases, cloud computing will necessarily become more industry-specific and modular, being consumable directly by line of business users or developers in the form of reuseable building blocks.

And we’re talking not just about services from the leading public cloud providers but also from the myriads of different SaaS vendors that will come up with new offerings to support better or new use cases.

Unlocking innovation comes after internal change

But new technologies and solutions don’t mean anything without an interal readiness to adopt them. Cloud computing is driving more and deeper organizational change by decomposing technology silos, processes and teams.

It is therefore no surprise that in that same 2012 Hype Cycle, the term “DevOps” was just making its premiere appearance in the magic quadrant with a 5-10 years projection to maturity (notice that hybrid cloud and hybrid IT fall in the same bucket).

This amazing universe of innovation on top of a new landscape of technology is forcing change and requires organizations to adapt to adopt.

Change is not always easy to implement. It involves people, technology, process…in other words, the “big picture.” It involves being able to navigate between managing the on-premises existing investments in infrastructure and applications and deciding what portion to modernize and what to replace with new, all while increasing the adoption of public cloud services.

It also involves defining new governance models that drive a new culture in the way development and infrastructure teams collaborate together, especially when new offerings are further decoupling the infrastructure layer from the application.

And of course, we can’t forget the critical requirement of managing risk during the process.

The cloud era is producing a huge amount of opportunity and innovation. And how do organizations respond? By building strategies based on where they are in their own technology journey. And that can take time.

 A new kind of hybrid solution

And that brings up back to the present. Our collaboration with AWS was exactly based on making that connection between our customers’ existing environments and the innovation of the AWS platform. Im other words, it takes into account the need to combine “the existing and the new” as part of their multicloud strategy and is aimed at customers that want to maintain control while extending their investments with interoperable components.

The Cisco Hybrid Solution for Kubernetes on AWS is the first hybrid solution in the industry to integrate directly with AWS’s managed Kubernetes offering (EKS) – essentially a hybrid Container-as-a-Service offering.

Cisco Tutorial and Material, Cisco Study Materials, Cisco Learning, Cisco Cloud

This means users responsible for deploying Kubernetes clusters and handing them off to developer teams don’t have to manually deploy and configure Kubernetes on top of AWS’s IaaS layer. They can use the solution to both deploy on-premises and trigger deployment on AWS EKS, creating a consistent environment for developers to run applications.

Practically speaking, it means less time spent on operations and a common authentication method across the two locations.

Futhermore, the part that makes the solution truly extensible and goes beyond containers, is the optional software that supports the full lifecycle of existing, non-containerized applications and hardware on-premises or in other clouds. CSR1000v for connecting, CloudCenter Suite for deploying, Stealthwatch Cloud for securing, and AppDynamics for monitoring.

The result? Customers can now make containers and Kubernetes a core engine of their strategy and innovation and increase adoption of public cloud services, without creating more silos that don’t integrate with their existing investments and assets.

Just like many areas of cloud offerings, Kubernetes-based solutions are maturing and driving change for organizations. Successful organizations in multicloud will not be the early adopters necessarily, but the ones that adopt the latest and greatest in the best way to fit their strategy.

Balancing the risks and rewards of connected manufacturing

The most expensive cyber security event ever, started with a software accounting package from the Ukraine. In its wake 25% of the world’s shipping was shut down, major automobile and pharmaceutical companies came to a stop. And now a major lawsuit between an insurance provider and its customer has come forward with the phrase “act of war” as a major point of contention.

Cisco Study Materials, Cisco Guides, Cisco Learning, Cisco Tutorial and Material

What factory manager saw that coming?

Chances are nobody did, and that’s why Cisco, Schneider Electric, and Aveva are working together to mitigate the risks of digital manufacturing so their connected industrial customers can seize IIoT’s many rewards.

Designing IT/OT networks with cybersecurity in mind

“What previously was protected by proprietary OT protocols and hard-wired connectivity across the factory floor is now open game to hackers trying to do their dirty work through targeted IoT endpoints — whether a smartphone, field engineer’s tablet, connected variable speed drive, or any IoT-enabled asset.”

So what to do? Where to start.

Let’s start with an attitude adjustment. While most ICS environments have an implicit trust model, we need to surround them with a resilient architecture built on a zero-trust approach. In short: allow only the absolutely necessary access to equipment and applications. It is a significant change and will require significant buy-in from all involved.

How to get there.

Segmentation – contain outbreaks and control access

Segmentation gives you the opportunity to stop those outbreaks while controlling access, whether it be a whole department or an individual switch port connected to a robot.

Start high – where the attacks first enter the factory – through the industrial DMZ. It is shocking how many modern Fortune 500 factories lack a properly managed firewall separating it from the enterprise network. Much of the impact of WannaCry /NotPetya could have been addressed with a properly configured firewall. The world’s most widely deployed next-generation firewall, FirePower, can help.

Next, work your way down through the Purdue model: Levels 3 down to individual machines, increasing granular control (micro-segmentation) along the way.  You will need to understand the production lines, their relationships, and componentry. To do that you have to have visibility.

Visibility builds better segmentation

Cisco Study Materials, Cisco Guides, Cisco Learning, Cisco Tutorial and Material
Visibility into your factory and processes is requisite for your segmentation decisions. You MUST find the process communication trails and work with the automation engineers to determine what is critical to ongoing operations. Cisco Stealthwatch can trace the full range of manufacturing communication patterns, from the factory floor, across the IDMZ to corporate ERP systems, to your favorite robot vendor’s cloud based analytics platform.

With an understanding of system communications, now build out a network architecture with modern network equipment. Look to resilient design concepts with multiple possible paths. Build for the future with Software Defined Networking for Software Defined Access (SDA). Cisco drives these policies through ISE (Identity Services Engine) which takes device or user identities directly or through pxGrid integrations with other Cisco products like IND (Industrial Network Director) or third party tools like Nozomi and others.

Visibility for the big picture

Visibility also drives understanding of process challenges including security threats.

Your DMZ NGFW should be able to determine if telemetry feeds are to be queried or simply pushed to analysis tools in the cloud or back at the research lab. Coupling your historians connection history at the plant with what is seen at the enterprise and beyond to the cloud based analysis site can cross numerous organizational and network boundaries through the stitching capabilities of Stealthwatch and Stealthwatch Cloud.

Visibility includes understanding the end-points in the factory. Are your engineering workstations or historians running without endpoint protections, making them potentially vulnerable to malware? ISE can tell you if end point protections are there, and of course you can remediate that threat with the deployment of AMP (Advanced Malware Protection).  And the plant floor itself? With the knowledge that your metal press has a vulnerable HMI (as determined by IND and ISE) and that the next maintenance outage is seven months away (as determined by the production calendar), you can quickly apply a Talos-produced SNORT rule to protect that machine via an ISA 3000 industrial NGFW at its gateway edge.

Close the loop with a security control loop

Just as a control loop takes inputs and adjusts the process, so, too, should your security see the state of your process system’s security and actuate the proper controls. Proper security controls are dynamic and adaptable. A microsegmentation capable architecture and network is the base from which you enable visibility into new equipment and behaviors. Visibility provides the knowledge (with help from the operations team) to drive the policies which the network and security controls will enforce. And this process is as connected as your modern factory because we can stitch together the factory activity with the enterprise – crossing former boundaries to create stronger and more secure bonds.

Now’s the time to secure your factory floor

All this represents a dramatic shift for manufacturers, OT professionals, and even IT departments.

At Cisco, we’re proud to stand at the forefront of the effort, alongside our partners at Schneider Electric and Aveva, to secure digital manufacturing and prevent negative outcomes.

Rakuten Cloud Platform is a Blueprint for the Future

Things that seem obvious today were not always that way. At some point, someone with a bit of courage and a flash of insight makes a bold move—like sticking a digital camera on the back of a phone. The rest of the world responds with a collective “of course!” and the world is changed, never to look back.

We had one of those moments a couple of weeks ago at Mobile World Congress in Barcelona when Rakuten announced their Rakuten Cloud Platform or RCP. Mickey Mikitani, Chairman, President and CEO of Rakuten introduced RCP the following way:

Rakuten has a founding vision of empowering people to realize their dreams and a history of disrupting the status quo to take the lead, in industries from e-commerce to fintech and digital content. We are very excited to launch a mobile network in Japan that is set to become the first choice of consumers and change global standards in telecommunications.

If you want to better understand how Rakuten is building RCP, I have some deep dive technical links at the end of this blog. For now, I wanted to explore why Rakuten decided to invest the time, effort and resources in building RCP.

For a while now, there has been growing tension between apps and services and the infrastructure they depend upon. This tension has increased as the center of gravity for app and service deployment has moved into the cloud. This, in turn, has given rise to cloud native architectures which further exacerbate stresses on infrastructure that was not originally designed for this brave new world.  At the customer end of things, we are now engaging with them in more ways and in more places. Not only do we have an explosion of phones and tablets, we are about to see an even larger explosion of connected cars, drones, cameras, refrigerators, and—my favorite—cows. Customers expect consistent and predictable services regardless of if they are at home, at play or on the move. Almost every network operator is making the investments to keep up with this sea change. But interestingly enough, app and service owners are also looking to take greater control of their own destiny. We saw the first movement in this direction with the large web players getting involved with projects like the Telecom Infra Project (TIP) and CORD. Their objective was to help service providers upgrade the infrastructure on which those web players were dependent to meet their growth goals. Netflix has, for years worked with ISPs to help improve the streaming experience of their subscribers. Rakuten has simply taken the logical next step. They are a cloud-first, mobile-first business and now they are building out bespoke infrastructure that is precisely calibrated to their needs. Moreover, as their business grows and evolves, Rakuten can be assured that their infrastructure will keep up with minimal lag.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials

While not everyone wants to be or can be Rakuten, it is worthwhile understanding what they did and why they did it, as that insight will be valuable to anyone contemplating an architecture refresh. Tareq Amin, CTO of Rakuten, built RCP around three guiding principles:

◈ Zero Touch, End-to-End Automation and Assurance
◈ Software Defined Programmable Infrastructure
◈ Distributed and Common Carrier Grade Telco Cloud

Looking at the first two principles, we can tell this is an architecture meant to be run by machines (hello SkyNet!). When we look at the scale of Rakuten’s vision and their goals for service agility and customer experience, it’s really the only feasible approach. For velocity, agility and cost reasons, humans simply cannot be inline to the day-to-day operations of RCP. To make this a reality, two things need to happen. First, every element of RCP needs to be programmable. For most of you reading this, deployment of programmable infrastructure (and the ability to take advantage of it) is opportunistic and incremental. Any progress is good news, however, there is significant difference between 99% programmable and 100% programmable. Anything less than 100% means at some point, someone is still sitting at a keyboard and introducing friction into your workflows and acting as a constraint on your business. Cisco’s contribution to Rakuten’s programmable infrastructure goal was our NFVI solution and our IOS-XE, IOS-XR and ACI-based transport platforms. They all provide rich, capable, programmatic interfaces that met all of Rakuten’s design requirements–no keyboards required.

In concert with programmability is automation. Much like programmability, partially automating a service chain is helpful, but having 100% coverage of your end-to-end service chain really unlocks new possibilities around how you build and deliver services. Are example, operationally, you lower costs of operation and reduce the time to stand-up and tear-down service chains. That opens up the door to more dynamic capacity management, auto-scaling and assurance management.  That increases your efficiency and utilization which further lowers opex and frees budget dollars for further investment and a virtuous cycle is spawned. From a customer experience perspective, real benefit comes from minimizing the lag between creation of services and ability of the infrastructure to support them. This frees service owners to iterate offers more quickly, experiment more easily and makes customization and personalization more feasible.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials

Rakuten’s RCP automation framework is two-tiered to provide flexibility and horizontal scalability. The bottom tier is comprised of four domains: central data center, WAN, edge data center and far edge data center. The domain level automation is built from a combination of Cisco Network Services Orchestrator (NSO), the NFVO Function Pack for NSO, Cisco Elastic Services Controller (ESC) as a virtual network function (VNF) manager, and, on an interim basis, other partner VNF managers—Rakuten’s mid-term goal is to consolidate on ESC.  NSO then uses a feature called Layered Services Architecture (LSA) to tie those four domains together with a cross-domain instance of NSO. Together, this framework provides RCP with fast, dependable, scalable, sophisticated end-to-end service orchestration. Rakuten then takes advantage of the rich northbound software interfaces NSO offers to tie the automation framework to their OSS and BSS systems.

The final principle, distributed and common carrier grade telco cloud, is a reflection of the changing nature of traffic. It no longer makes sense to try and serve subscribers from some far-away central data center. Providers can also no longer make assumptions as to where their customers are located. Instead, RCP needs to be able to serve customers wherever they are, whichever device they are on, whatever service they are consuming. For both customers and service owners, Rakuten needs to be able to pervasively deliver consistent capabilities and predictable customer experience. Let’s take a closer look at how they do that and where we contribute to the effort.

A “telco cloud” is essentially a private cloud optimized for hosting virtualized network functions (VNFs). It is built from NFV Infrastructure (NFVI) that hosts the VNFs and a management and orchestration layer (MANO—discussed earlier). Cisco Virtualized Infrastructure Manager (CVIM) is an open, modular containerized NFVI software solution that forms the building blocks of RCP. The RCP deployment embeds Red Hat Enterprise Linux and Red Hat OpenStack Platform. Beyond support for Cisco and 3rd-party VNFs, CVIM provides key features like security hardening, automated zero-touch provisioning and full lifecycle management of VNFs. Underpinning it all, Cisco ACI and Cisco Nexus 9000 series switches link network, compute and storage resources.

RCP’s CVIM building blocks are flexible and fungible so a collection of CVIMs can be adapted to support any service or application today or in the future. This gives Rakuten great cost efficiencies with RCP, but it also gives service owners great freedom to build new services and get them deployed quickly without worry about what the infrastructure can or cannot do. At the same time, these basic NFVI building blocks can be deployed anywhere along the service chain that makes sense, since managing a CVIM instance in the central data center is no different than managing one in a far edge data center. Along those same lines, VNFs, content and resources can be placed and even moved around on the fly to optimize operations and customer experience—distributing them to wherever makes the most sense.

Mickey Mikitani stated “[w]ith automation and virtualization, Rakuten is redefining how mobile networks are designed and how services can be consumed.” RCP seems ready to do exactly that. Not only will their investment in RCP help Rakuten and its customers, it will serve as lab for their peers to learn and the industry to evolve.

Calling in Webex Teams Now Powered by Cisco BroadCloud

A proven calling platform that brings cloud innovation to the mid-market and large enterprise.

Today Cisco announced a new enterprise-class, native cloud solution – Webex Calling. It’s powered by bringing together the best of the proven Cisco BroadCloud platform as well as Cisco Webex. This brings Cisco’s total business cloud calling users to over 29 million worldwide. By combining a full enterprise PBX feature set with the rich team collaboration capabilities of Webex Teams, Webex Calling delivers the complete, integrated collaboration experience business users need. It will be sold under the Cisco Collaboration Flex Plan by Cisco VAR channel partners. Availability begins in the U.S. on March 31, 2019 and will expand to more than 35 countries across North America, Europe, Australia/New Zealand, and Japan by the end of the year.

Cisco BroadCloud, Cisco Tutorial and Materials, Cisco Learning, Cisco Guides

We are already seeing a great fit in the market from our early partner engagements.

“The release of Webex Calling is timed perfectly with a phone refresh Presidio is doing for an important retail customer. The customer recognized immediately that they could configure, deploy, and manage over 2,500 handsets across 500 locations in nearly a plug-and-play fashion utilizing a lean IT team while saving hundreds of thousands of dollars in telecom costs,” said Vinu Thomas, CTO of Presidio. “The flexibility of adding and removing phones, the access to the full suite of Webex’s collaboration offerings, and the ease of automatic updates and patching are just a few of the reasons Webex Calling is a tremendous opportunity for Cisco partners and their customers.”

Superior alternative

Mid-market and enterprise business leaders have been reluctant to move to the cloud, due to concerns about scalability, feature functionality, reliability, and security. That’s why we only see a current cloud calling market penetration estimate of 8% for businesses with 100+ users, while the cloud penetration for the under 100 user segment is more than 25%, based on market analyst estimates.

Webex Calling eliminates these former barriers and gives business leaders the freedom to replace their aging PBX infrastructure with a superior cloud PBX alternative. With cloud delivery from a series of geo-redundant data centers in seven countries, operated by experienced Tier 4 operators, Cisco is able to deliver a multi-tenant cloud service that is more reliable, scalable, and secure than any on-premises option. And with a cloud service that counts release cycles in weeks, rather than years, Webex Calling is always up to date, delivering a more intelligent user experience.

Complete solution

Now Cisco can take users from their smartphone in their car, to the devices they use in their office, home, or meeting room with easy device handovers and rich business calling features at every step. With Webex Teams included, we’re making it simple to keep organizations connected and productive from wherever work gets done.

Here’s what you get with Webex Calling:

◈ A proven, enterprise-class cloud PBX
◈ Bundled with Webex Teams, for advanced collaboration
◈ Optional Cisco multiplatform (MPP) IP phones, headsets, and video devices
◈ Option to add Webex Meetings
◈ Simplified packaged pricing
◈ Investment protection through Cisco Collaboration Flex Plan purchasing
◈ Sales and service support from a qualified Cisco VAR channel partner

Smooth transition

In most cases, larger businesses need more time to transition over to the cloud. In some industries, like financial services, they may not ever move completely to the cloud. That makes the time and process in this transition zone a key gating factor for these business leaders.

One of the most important advantages we see with Webex Calling is the flexibility it offers for customers looking to transition to the cloud in phases, rather than all at once. Cisco customers now have the freedom to move any site, or group of users to the cloud, while maintaining a common network dial plan and directory access for users across all cloud and on-premises PBX sites.

Powerful channels

Webex Calling will be sold primarily by Cisco value-added reseller partners (VARs) that are trusted by enterprises worldwide. So now mid-market and enterprise customers can get the performance, reliability, and security of a Cisco cloud calling solution from the Cisco channel partner they prefer, or are currently doing business with.

Early excitement and momentum with our VAR partners is building. Here’s what Joe Berger, Practice Director, Collaboration and End User Computing for World Wide Technology had to say. “As the UCaaS market continues to mature, we’re excited to have Webex Calling in our portfolio. The Cisco BroadCloud powered solution now gives us more options for those customers who are looking to move their collaboration workloads to the cloud . . . backed by the enterprise requirements that many businesses already expect from Cisco. When combined with Webex Meetings and Webex Teams, this truly becomes a next generation collaboration platform.”

Web & Mobile On-prem Solution Maximizes Customer Experience

Business overview

The increased relevance of web sites, chat, and mobile applications on smartphones is supporting a big rush to evolve customer care into a digital omnichannel architecture. Enterprises recognize how these new ways of communicating are becoming increasingly important for reaching their business objectives. The true omnichannel experience that companies are aiming to achieve is the ability to carry the context along different channels to maximize the customer experience and to deliver high quality services along the entire customer journey.

Video Advisor enables a compelling digital journey by seamlessly integrating with Cisco Customer Journey Solutions such as CCX, CCE, PCCE, HCS and empowers companies to enable real-time video agent engagement and escalation directly in their applications and website channels, making it easy for customers to interact with experts when, how and where they choose. The resulting customer experience of moving seamlessly from one channel to the other results in an improved business outcomes and customer loyalty.

Product overview

Video Advisor features at a glance:

◈ Web and iOS/Android smartphone SDK’s
◈ Audio/Video WebRTC to SIP on premise signaling server
◈ Media transcoding/ pass-through and firewall traversal
◈ WebRTC Cisco Finesse gadget
◈ Co-browsing, Link and Document Asynchronous Sharing, or double sidereal time Desktop Sharing

Integrates with Cisco’s Customer Care Architecture Portfolio:


Multiple Audio/Video options for the customer

Video Advisor is the Eudata® solution to set up Video Sessions between customers and Agents: it allows the customer to contact an expert in the Cisco Contact Center through Audio and Video calls directly from the company web site or iOS/Android smartphone applications:

◈ WEB: Add a simple “Click To Call” button on your web site to provide real-time support to customers and users
◈ SMARTPHONE: Add Video Capabilities to your mobile APPs using native SDKs to enrich your customer experience
◈ KIOSK: Create Video services available from a public Kiosk (based on PCs or on mobile devices)

Browser/device compatibility matrix:

Video Advisor takes advantage of modern browser APIs to enable application/desktop sharing and WebRTC capability. For older browsers, like Internet Explorer, a plug-in is needed for access those functionalities.

WebRTC to SIP architecture and call flow

Video Advisor is based on WebRTC technology to offer an Internet video phone to customers using web sites, mobile applications, or kiosks.

Through the Eudata® WCS on-premise WebRTC2SIP component – that acts as a middleware between digital customer touch points and the Cisco Customer Journey Solution through the Universal Queueing API (CCX, CCE, PCCE and HCS) – the incoming WebRTC session is turned into a SIP call sent to the customer care solution for treatment. Video Advisor is therefore fully integrated with Cisco CVP and Cisco CUCM for routing calls to the desired expert.

◈ An Audio/Video Web RTC call is initiated either by a web widget, a smartphone application, or a kiosk.
◈ The audio video Web RTC call originated by the customer is translated into a SIP call by the WCS WebRTC2SIP server and sent to Cisco Customer Care where it is handled as a regular incoming SIP call and so finally routed to the agent. Customer details can be sent as SIP headers in order to display on agent desktop.
◈ The call is terminated on a customer care agent SIP endpoint.

DevOps with CloudCenter and Kubernetes in a Multicloud Environment – Part 1

The need for digital innovation

Whatever your business might be, your internal and external customers expect more and more services, greater efficiency and a better experience. Providing new services (which in most cases will mean a new or revamped application) to customers and anticipating your competitors’ moves attracts new customers and retains the existing ones.

Often the line of business developers are not satisfied with the support they receive from the IT operations teams in terms of flexibility and speed to start a new project, especially if new technologies or skills are required (e.g. developing and deploying cloud native applications).

The perception of IT operations depends also on the frequency of supporting the efforts of releasing fixes for broken services and on the process of testing so that production environments are “bug-free”, after going through functionality and reliability tests.

Frequent releases and the quality of the code can benefit a lot from automation in all the phases of a software project, though end-to-end automation is not absolutely necessary; it’s just much better!

The fundamental pillars are organizing workflows and processes to ensure they cover every need (no gaps in the responsibility, no grey area in communication among different departments, shared objectives instead of finger pointing).

Figure 1 below shows the evolution of methodologies and the impact on the value perceived by the business. The stars represent the moment when business value is realized by a release of the application in production.

With traditional waterfall projects, it happens only at the end of the project (by the way, with a lot of uncertainty due to delays and unexpected trouble during the development and the test phases).

Agile methodology reduces risk by repeating shorter cycles of design, coding and testing that can address any surprises and adjust the course of the project sooner if necessary. But deployment in production still happens at the very end of the project.

The innovation allowed by Continuous Integration and Continuous Deployment (CI/CD) brings the application in production at every cycle (new releases or bug fixing) ensuring optimal quality and a deterministic outcome: the business will appreciate the benefit in terms of time-to-market for their initiatives.

Figure 1 – CI/CD offers more business value

DevOps is not a technology nor a product

DevOps means collaboration between Developers and Operations.

The work of whoever is responsible for design and implementation of the code (the dev team) does not finish when a new build of the application is released. Developers should also collaborate in testing the entire system (code, infrastructure and process), releasing it in production, operating and measuring its KPI.

The Operations team do not just execute a defined process to maintain the system but should collaborate since the design phase of the application and, most importantly, provide constructive feedback from the production environment that can help improve and extend the application in next development cycles, e.g. application errors and their reason, performances issues, support tickets opened by users, etc.

The collaboration and the feedback loop are foundational principles in DevOps, as described in next paragraph. 

Cultural change

Necessary cultural change should be promoted (breaking silos in the organization), with incentives and gradual adoption of practices that will improve with time: the entire organization and the individuals have to digest a new way of working, openly analyzing its outcome and contributing to the progress with personal feedback and suggestions. A great book describing this cultural change is the Phoenix Project.

DevOps practices suggest that the entire lifecycle of a service is managed by a single team: from the inception phase and the requirements analysis, to the implementation, testing, release and related operational processes. They can be more efficient and provide more value if they know everything about the service and they can react to any problem quickly, as well as evolving it based on new requirements.

The DevOps team should include representatives from different departments (lines of business, IT Architecture, Operations…) that bring their skill and experience, so a new organizational model may be required. The result can be a “dotted-line” reporting structure with functional responsibilities across different teams.

It is not necessary to build a team for each service. Some services can be grouped in one team, especially if they belong to the same business area or if they are responsible for the building blocks of a composite application (in a microservices architecture).

DevOps principles

Gene Kim defines the principles of all DevOps patterns (the Three Ways) in the books “DevOps Handbook” and “The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win.” He asserts that the Three Ways describe the values and philosophies that frame the processes, procedures, practices of DevOps, as well as the prescriptive steps.

The First Way – Systems Thinking

◈ Understand the entire flow of work
◈ Seek to increase the flow of work
◈ Stop problems early and often – Don’t let them flow downstream
◈ Keep everyone thinking globally
◈ Deeply understand your systems

First Way Goals

◈ One source of truth – Code, environment and configuration in one place
◈ Consistent release process – Automation is essential (one click)
◈ Decrease cycle times, Faster release cadence

The Second Way – Feedback Loops

◈ Understand and respond to the needs of all customers (internal and external)
◈ Shorten and amplify all feedback loops
◈ With feedback comes quality

Second Way Goals

◈ Defects and performance issues fixed faster
◈ Ops and InfoSec user stories appear as part of the application
◈ Everyone is communicating better
◈ More work getting done

The Third Way – Synergy

◈ Consistent process and effective feedback result in agility
◈ Now use that agility to experiment
◈ You only learn from failure – So fail often, but recover quickly

Third Way Goals

◈ Ability to anticipate, even define new business needs through visibility in the systems
◈ Ability to test and optimize new business opportunities in the system while managing risk
◈ Joy

Now that we have covered the basics of DevOps, let’s have a look at a product from Cisco that could make it easier to adopt DevOps practices. Remember that DevOps cannot be bought: it is the set of good practices that you define and refine as continuous improvement based on experience. Automation is only a part of the story.

The Cisco multicloud approach

Many organizations are using at least one private or public cloud, but more and more use a combination of different clouds: that implies a need for consistent governance, security, networking, analytics and automation that apply to every environment.  The multicloud portfolio includes products, services and reference architectures that span all technologies mentioned above to make the adoption of clouds simpler.

This post explains how we have built a demo using products in the automation bucket to support a DevOps use case (i.e. Continuous Integration and Continuous Deployment, aka CI/CD).

The two products are the Cisco CloudCenter Suite (CCS) and the Cisco Container Platform (CCP), briefly described in the following paragraphs before we go on to the demo.

Cisco CloudCenter Suite

Cisco CloudCenter Suite is a solution that helps the IT organization to enable developers and lines of business to deploy and operate a large number of applications and middleware platforms, made more complex by the availability of different possible targets (private and public clouds for running VM and containers).

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials

Figure 2 – CloudCenter Suite addresses the many-to-many complexity

CloudCenter Suite is a single tool that simplifies multicloud management by enabling organizations to design, deploy, and optimize infrastructure and applications across clouds by automating application deployment and consuming resources and services from any cloud. It helps to enforce a single governance model including cost control, approval processes, security policies and consistent architecture across different clouds.

The benefit is that you don’t have to learn and use the different tools from cloud providers, or replicate the automation blueprints using the native automation technologies in each cloud (e.g. Cloud Formation for AWS, Heat for Openstack, Powershell for Azure): you only create a single model and CloudCenter Suite translates it into a call to the specific API exposed by each cloud, including public, on-premises and Kubernetes clusters.

Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Study Materials

Figure 3 – CloudCenter Suite translates a single blueprint to API calls for all clouds

Everything you do in CloudCenter Suite can be done through its API, making it easier to orchestrate it externally (e.g. from Jenkins, through a plugin that Cisco ships so that you can insert multicloud deployments in your CI/CD pipeline).

The current version of the CloudCenter Suite also includes additional modules like the Cost Optimizer and the Action Orchestrator: a useful enhancement to create a governance model and make operations easy in a heterogeneous multicloud environment.

Cisco Container Platform

Cisco Container Platform is another software product from Cisco, that Operations teams can use to create and manage enterprise-grade Kubernetes clusters. It deploys, fully configures and manages (upgrades, scales, monitors) Kubernetes clusters on-premises and in the public cloud for you – it also supports additional native integration with AWS’s EKS. It takes care of all the complexity of integrating with networking (options offered out of the box are Calico, Contiv and Cisco ACI), storage, security (SSO and RBAC are added to Kubernetes) as well as centralized monitoring and logging (Elasticsearch, Fluentd and Kibana) while shipping 100% open source binaries from the upstream repositories. With Cisco Container Platform, DevOps teams can now extend their deployment environments to include Kubernetes-based containers, without the complexity of having to actually deploy and maintain it themselves.

Open programmable architecture delivering value beyond connectivity

We discussed how Cisco delivers consistency and simplicity, with integrated security, across Enterprise domains. Now we’ll discuss in more detail how this is done.

“People who are serious about software should make their own hardware”

Cisco uniquely develops its own hardware and software, including silicon for Switching, Wireless, and Routing platforms. This allows Cisco to deliver unique innovations and optimizations pertaining to network-specific needs, such as:

◈ Stackpower/Stackwise,  AVB, MACSec-256, and ERSPAN for Switching
◈ CleanAir, Flexible Radio Assignment and Hyperlocation for Wireless
◈ Advanced hardware queueing and Deep Packet Inspection for Routing
◈ Flexible Netflow (FNF), Scalable Group Tags (SGT), VXLAN, and NBAR2 across all the domains

These unique innovations in hardware and software enables Cisco to deliver a lot more value beyond connectivity in the areas of security, visibility, high availability, etc and are the foundation for the evolution to an Intent-based architecture.

Built-in Security and Network Visibility for Proactive Insights

FNF and NBAR2 are foundational enablers for Security and Application Visibility embedded in the platforms. Cisco Switching, Routing and Wireless platforms incorporate special hardware and software to collect information about all the flows in the network, not just sampled, and deep packet inspection capability to identify applications. All this is done without network slowdown. This is what makes advanced Security services such as Encrypted Traffic Analytics (ETA) able to detect malware in encrypted traffic without decrypting the traffic, working in conjunction with Cisco Talos, Cognitive Threat Analytics (CTA), and Threatgrid while using Cisco Stealthwatch. It is also what enables Application Assurance, advanced Application Policy, and Network as a Sensor.

◈ Granular Visibility: Model-driven telemetry (MDT, otherwise known as Streaming Telemetry) provides a mechanism to stream data from Switches, Routers, and Wireless devices to a destination. By subscribing to a data set defined in a YANG model, the specific event data can be streamed on-change, providing near-real-time monitoring of the network, leading to quick detection and rectification of failures.
◈ Intelligent Capture: Gather contextual data ranging from live client onboarding to on-demand RF scanning to real-time Wi-Fi analytics and client location. Actionable insights are provided by analyzing packet captures across multiple network elements, with zero packet loss.

Simplified Management for an Always-on Network

Network Automation is a new paradigm for network configuration, operation and monitoring. Cisco’s solution delivers the following across wired and wireless in the Enterprise:

◈ Automated device provisioning: This is the ability to automate the process of upgrading software images and installing configuration files on Cisco Switches, Routers, and Wireless devices when they are being deployed in the network for the first time. Cisco provides turnkey solutions such as Plug and Play (PnP) that enable an effortless and automated deployment. Automatic device provisioning is also provided using Zero Touch Provisioning (ZTP) which, while not a turnkey solution like PnP, is offered for greater flexibility and compatibility with numerous device types.

◈ API-driven configuration: support a wide range of automation features and provide robust open APIs over Network Configuration Protocol (NETCONF) using YANG data models for external tools, both off-the-shelf and custom built, to automatically provision network resources. Most platforms also support Restconf and GNMI APIs.

◈ Seamless software upgrades and patching: To enhance OS resiliency, Cisco IOS XE supports patching, which provides fixes for critical bugs and security vulnerabilities between regular maintenance releases. This support allows customers to add patches without having to wait for the next maintenance release.

◈ Application Hosting: Cisco Switches and Routers support hosting of applications directly in the infrastructure. Container/VM App hosting for Analytics, Security, IOT, Validation/Troubleshooting tools (Wireshark, iPerf, etc), Cloud Connectors, CI/CD applications, and more. These platforms support local storage starting from 120GB and above to store application data.

Orchestrating and Assuring the network from an Enterprise-wide view

Custom ASICs enable Cisco to future proof customers for the ever-changing digital businesses, by delivering beyond standards. Modern and modular IOS-XE support across the portfolio supports IT simplicity and scale. More importantly, all Cisco’s next generation platforms are built from the ground-up for Intent Based Networking (IBN). Cisco SD-Access, Cisco’s IBN architecture for the Campus, provides automated end-to-end segmentation to separate user, device and application traffic.

Cisco SD-Access automates user access policy so organizations can make sure the right policies are established for any user or device with any application across the network. Instead of defining a policy for your LAN, wireless LAN and WAN, you only define it once and apply it to all three domains. SD Access provides the ability for “policy-based automated network enforcement” for access, security, application quality and monitoring, across ALL network domains. Cisco SD-Access delivers macro-segmentation using Virtual Networks (or VRFs) and micro-segmentation using Scalable Group Tags (SGTs). VXLAN is the dataplane encapsulation protocol carrying the Virtual Networks and SGTs and forwarded with the specialized silicon in the hardware platforms, while LISP is the fabric Control Plane protocol keeping track of devices and users as they connect and move in the fabric.

“It is clear that SD-Access is the future; it is the only way we can keep up with the explosion of connected devices” 

Cisco DNA Center is the single pane of glass where all of this comes together. It is the single point of Orchestration, Automation, and Assurance for the network.

◈ Automation for Provisioning: Software Image Management (SWIM) manages the images for your network devices and, when it detects a device is not conformant with images deemed as “Golden” in your environment, can automatically update the device. Cisco Plug-n-Play (PnP) enables zero-touch deployment for new devices as they are added to your network.

◈ Analytics for Assurance: Cisco DNA Center receives contextual information from the network devices, endpoints, and applications and delivers rich assurance functionality. It delivers unprecedented visibility, proactive insights, real-time troubleshooting, and predictive performance.

“The new Cisco Catalyst 9000 provide us performance we need, and the security features that are critical for our healthcare records. The new network, powered by Cisco® Digital Network Architecture (Cisco DNA), gives us granular insight into who’re the users, the devices they use, and the applications they access—all with the ability to learn and adapt to changes and needs in the network.”

Cisco DNA Center is also the place where the network can be designed, policy is created, and devices are deployed in the network, for SD-Access (fabric based) and non-fabric based environments. Next time we’ll explore DNA Center a bit closer. In the meantime, here is a teaser showing Wired and Wireless Client Health in DNA Center.
