SaaS-based Kubernetes lifecycle management: an introduction to Intersight Kubernetes Service

The transition to cloud native application architectures is rapidly growing and becoming mainstream, increasing the need for container operationalization and management. According to a Gartner report, “growing adoption of cloud-native applications and infrastructure will increase use of container management to over 75% of large enterprises in mature economies by 2024, up from less than 35% in 2020.”

Three years ago we launched Cisco Container Platform (CCP), a self-hosted software container management platform, based on upstream Kubernetes, offering integrations with all the popular public clouds as well as any hardware on-premises. As we have been enabling customers in their containerization and DevOps journeys, we always come across the three key personas that we are trying to help: IT Admins, DevOps and development teams.

◉ IT Admins, responsible for not just for the Kubernetes layer but also the end-to-end cloud infrastructure. They are looking for common tools to easily deploy, manage, visualize, and monitor across the entire infrastructure stack, from server firmware management, to the hyperconverged layer, to the automation and container lifecycle management.

◉ DevOps teams are responsible for the stack’s Day 2 operations. They are looking to protect the precious application data and automate deployment to be able to scale across both infrastructure and application stack.

◉ Development teams want a simple API to hide infrastructure complexity and tools to automate continuous delivery of their Kubernetes-based applications.

The feedback was consistent: how can we expand the functionality of our container management offering to enable integrated management of the complete infrastructure stack under the Kubernetes layer?

That’s exactly why we built Intersight Kubernetes Service.

Expanding Intersight with Kubernetes management

Back in October this year, at Cisco’s Partner Summit, we made a series of announcements under a common umbrella message of “simplifying IT operations across multicloud”. One of them was regarding Cisco Intersight and its evolution. Cisco’s Intersight, from a Cisco data center infrastructure management solution, is becoming a comprehensive cloud operations platform, helping users simplify the management and optimization of infrastructure, workload and applications – on-premises and on public clouds.

One of the first brand new modules to come out of the exciting new Intersight roadmap is Intersight Kubernetes Service (IKS). IKS effectively expands the Cisco Container Platform’s functionality to benefit from Intersight’s native infrastructure management capabilities, further simplifying building and managing Kubernetes environments. IKS is a SaaS offering, taking away the hassle of installing, hosting, and managing a container management solution. For organizations with specific requirements, it also offers two additional deployment options: (with a Virtual Appliance). So let’s take a look at how IKS can make the lives of our personas easier.

Building an end-to-end data center and edge Kubernetes environment with a few clicks

A good example comes from the retail sector: an IT admin needs to quickly create and configure hundreds of edge locations for the company’s retail branches to do AI/ML processing and a few core ones in privately-owned or co-located data centers. The reason it makes sense for processing or storing large chunks of data at the edge is the cost of shipping the data back to the core DC or to a public cloud (and latency to a certain extent).

Creating those Kubernetes clusters would require firmware upgrades, OS and hypervisor installations before we even get to the container layer. With Cisco Intersight providing a comprehensive, common orchestration and management layer, from server and fabric management, to hyperconverged infrastructure management to Kubernetes, creating from scratch a container environment can be literally done with a few clicks.

IT admins can use either the IKS GUI, its APIs or integrate with an Infrastructure as Code plan (such as HashiCorp’s Terraform) to quickly deploy a Kubernetes environment, on a variety of platforms – VMware ESXi hypervisors, Cisco HyperFlex™ Application Platform (HXAP) hypervisors and/or directly on Cisco HyperFlex™ Application Platform bare metal servers (coming soon) – enabling significant savings and efficiency without the need of virtualization.

Similar to the Cisco Container Platform, IKS will also soon support public cloud integrations with all the popular providers. After deploying the environment customers can easily lifecycle manage the entire stack as shown in this video (shown between 1.49-3.22).

Adding full-stack application visibility with Intersight Workload Optimizer

DevOps teams want to bridge the application and infrastructure gap as much as possible. They would be looking to right-size their application replicas (vertically and horizontally scaling of pods and nodes) based on traffic load. A benefit of IKS is that users can connect their Kubernetes workloads to another Intersight SaaS module used for application resource management, Intersight Workload Optimizer, and benefit from right-sizing their containers (by monitoring the traffic between the pods) as explained here (4.23 – 6.11). This way customers can get maximum ROI from the different locations where capacity can be an issue such as edge locations.

At the same time, IT Admins are always aiming for complete visibility across the application and infrastructure stack, beyond just the Kubernetes layer. As both IKS and IWO are part of the same platform, users can get a comprehensive view on the health of the entire stack, which is crucially important when remediating.

Stay tuned for our big IKS general availability launch in February 2021

As we work on the roadmap for IKS and the new features it will bring, we couldn’t be more excited to work with customers exploring new grounds on how to offer more value and accelerate IT operations.

The Future of the Cell Site is the Router

Evolving Cell Site to Multi-Service Cell Site

With 2G, Cell Sites were primarily (designed around circuit-switched TDM Based connectivity and ) responsible for enabling Voice traffic. As the 3G/4G picked up momentum, Cell Sites were upgraded to carry (IP based traffic for) both Voice and Data traffic. This upgrade of Cell Site functionality aligned well with the profitability of Operators. The networks which were aggressive in this transition of Cell Site enabled the profitability. With the 5G around the corner, the role of the Cell Site will be even more crucial. It plays a critical role in adding a new revenue stream, enhance the current offering, and build the business case for 5G adoption. Cell Sites would need to evolve to Multi-Service Site which would offer new revenue-generating streams like B2B service for Small Enterprises and SMB customers, enhanced user experience for social media and streaming services, public safety applications, IOT/Smart City applications, and far edge use cases.

For the Multi-Service Cell Site – it’s imperative that it would demand much higher bandwidth, resiliency, and significantly lower latency. However, most of the Cell Site deploys sub-optimal architecture with layer 2 technologies. While layer 2 solutions have a lower capex, they tend to have higher opex and extremely restrictive in terms of new service creation. To realize the full potential of the Cell Site, it’s critical to bring Layer3 to Cell Site. The backhaul networks have already evolved from MPLS-TP / TDM to Layer3/IP-MPLS-SR. Extending these technologies to Cell Site will bring significant benefits to the service which can be delivered.

Cisco Converged 5G Transport

Let’s look at some of the key benefits of such evolved architecture:

Robust Infrastructure: The Infrastructure which enabled 3G/4G will not be sufficient to fully realize the potential of the Multi-Service Cell Site. It needs to secure, redundant, reliable, scalable, and SDN enabled. Any compromise on this aspect could result in sub-optimal performance of the network. Using Router/Layer3 based devices at the Cell Site would enable:

◉ Site Sharing/Densification

◉ Best in class Timing capability with Class C precision and SyncE up to the cell site

◉ Carrier-Class Reliability and Redundancy

◉ Consistent OAM end to end

◉ Trust Worthy System with complete visibility of Device Security health.

Service Agility: As we look ahead and build a business case for 5G investment, every network port in the cell site would be viewed as a service port. Uniform function availability / Flexibility and consistency of features will be of utmost importance. The gateway device at the cell Site should have the capability of Network Slicing / Service Demarcation / Quality of Service / Monitoring capability of Service and seamless integration. The Cell Site router provides all the capabilities mentioned along with:

◉ Ease of Integrating 5G Core with AMF/SMF/UPF.

◉ End to End Network Slicing

◉ Seamless Service provisioning & workflow

◉ Consistent QoS across the network

◉ Consistent Service Monitoring across the network.

Operational benefits: Apart from the Capex investment and generating the business case for new revenue-generating streams, the subject of Operational Expenditure has also been the primary part of the 5G journey. It’s unfathomable to build a network that relies on manual intervention apart from racking and stacking activities. Using Router at Cell Site will make the operation seamless and aligned to the rest of the networks. Consistent Tools cross the network allow for stronger control over the network. While the Backhaul & Edge networks have been using the Automation capabilities for a while, given the remoteness of Cell Site – it’s even more critical to have an Automation-first approach for the Cell Site. Features like ZTP, Telemetry

◉ End to End Automation and tighter integration with backhaul.

◉ End to End Layer3/IP for consistent reporting & analytics

◉ Reduced network Touch Points

How I Got Started with Network Automation

Recently I joined the Cisco DevNet team as a Content Developer Engineer. This is exciting for me, because I have an opportunity to merge the two things that I love most: learning more about network automation and helping the IT community grow within their skills.

This year marks 20 years that I have been in information technology. I’ve seen the industry change multiple times, and right now we are in the middle of another major shift. That shift is being driven by organizations needing to expand and extend their networks, resources and services rapidly and at scale. In other words, automation.

By the end of this post, I will share my journey into network automation, Cisco Systems, as well as provide you with everything you need to join the #DevNetClassOf2020. Quick note: I am also going to let you know how you can get a 25% off exam voucher too!

How I started with Network Automation

In my career, the greatest rewards have come when I have stepped outside of my comfort zone and taken some risks. From joining the Military (USAF), to starting my YouTube channel, learning Python, and now being a part of Cisco Systems. Each one of these moments has helped me get to where I am today. Now that I am here, I am committed to helping you walk, run, and fly in network automation! Are you ready to step outside of your comfort zone?

Three years ago, I was a Systems Administrator working in a comfortable government position. Back then, I thought I would never need to learn to code. To be honest, I could have stayed in that environment, but I decided to take a risk so that I could follow my passion which is network engineering.

In that position, I was tasked with some highly visible projects that drove me to learn the programming language Python. My road to this point has been awesome. I am DevOps certified, DevNet certified, and I have been in a NetDevOps role for the past year. Balancing software sprints and network engineering have prepared me for this new role within Cisco Systems.

Learning Python

People ask me often, “do you need to know Python as a network engineer?” The answer is no you do not… That is until you need a tool to perform a task that has not yet been created. Python gives you the ability to customize and create applications as you need them.

When I first began coding, I could have started with Ansible. However, I found Netmiko to be one of the best tools available for network automation. Because it allowed me to write my python scripts and then parse my return data exactly as I needed. So, I started there. My first automation script was to change the Simple Network Management Protocol (SNMP) configuration for over 300 devices in our network. My second automation script was to update the enable secret password on 700 devices. All of this was achieved in under 50 lines of code. This task normally would take days, to manually login and update each router and switch. But with the power of automation, I took about a day to write and test my code in a nonproduction environment. Then about 30 minutes to run and verify the completion of my script in production.

How you can get started

When I started automating, learning resources were scarce on these topics. Now, you have a great opportunity to leverage platforms like the DevNet sandbox. Here you can access multiple Cisco platforms and labs that will walk you through utilizing tools like Python, Postman, and Ansible to configure and manage your networks. Many of these resources are free and always available. If you are totally brand new to automation, I recommend you visit the “Start Now” page on DevNet to get started.

Get DevNet Certified

One of the top questions being asked of network engineers right now is, can you automate? Organizations want to manage their networks more effectively and efficiently. The Cisco DevNet Associates certification can set you on the path to do that. The certificates not only validates your skillset but also will add value to your resume to help you stand out. Lastly, the DevNet Associates certification will give you the ability to speak the same language as software developers and other automation stakeholders.

Here’s a link for a 25% off exam voucher. If you pass before the end of the year, you will get a cool digital badge, free DevNet merchandise, access to special DevNet sessions with the one and only Susie Wee, Senior Vice President and General Manager of Cisco DevNet & CX Ecosystem Success. 

Call to Action

If I can automate, so can you! Change is inevitable and the more you embrace it, the further ahead you will be. I wish you much success on your automation journey. I look forward to welcoming you to the #DevNetClassof2020.

Cisco MDS 9000 and IBM FICON: Just Got Married Again

We know humans like to celebrate. The wedding date represents a significant one for many couples and there is a tradition to celebrate again, even if with less fanfare, upon reaching a specific amount of years together. Apparently originated from an ancient German tradition, there is also a symbolic name to represent how long ago the wedding occurred. For example, the golden wedding indicates 50 years of marriage.

Cisco MDS 9000 series and IBM mainframe FICON have not reached that level yet. The original wedding date was in 2004, and 2020 marks 16 years, assuming my math is not wrong. There is a name for this, despite not popularly used. It is called ivy wedding….but don’t ask me why.

IBM originally announced FICON channels for the S/390 system in May of 1998. Since then, FICON has evolved from 1 Gbit to the 16 Gbit FICON Express16S channels, announced in January 2015 in conjunction with the IBM Systems z13. Each generation of FICON channels offered increased performance and capacity. Initially, the FC-SB-2 Fibre Channel upper-level protocol (ULP) was used by FICON. As the name implies, a single byte (SB) link address was used to specify the switch port on the director, out of a range of 00-255. It supported key features like native FICON storage devices, channel-to-channel connections, FICON directors (or switches), and more. But it did not allow for switched paths over multiple directors. In 2003, with the introduction of a new and enhanced ULP, this limitation was removed. In fact, FC-SB-3 employs a dual byte address.

Funny enough, rather than changing the name from SB to DB, it was decided to change the version instead, increasing its number from 2 to 3. This was the beginning of cascaded FICON. Two directors per fabric, also known as single-hop cascading, became possible since then. Recently multi-hop cascading has been qualified and has opened up new deployment options. Fibre Channel Single-Byte-4 (FC-SB-4) standard followed in 2008 and accounted for a big step forward in terms of performance, by reducing FICON channel overhead with the introduction of the high-performance FICON for System Z (zHPF).

A few years later, FC-SB-5 was standardized and in 2020 work is still in progress for the FC-SB-6 standard and new improvements are expected. Meanwhile, new routing schemas have come along, specifically FICON Dynamic Routing (FIDR), creating an exchange-based routing model (OXID-based routing). Meanwhile, the mainframe gained enhanced monitoring capabilities for switching devices with a revamped version of the CUP protocol.

Just as the protocol and the topologies have evolved over time, the same is true for requirements, expectations, and underlying hardware products. Cisco MDS 9000 series has just completed the most stringent testing and validation exercise, successfully receiving its latest FICON certification letter and can be found on the IBM resource link page (registration is needed to access this website).

With software version, NX OS 8.4(2b), Cisco MDS 9710, MDS 9706, and MDS 9250i and their IBM c-type counterpart have renewed their approval for use within mainframe environments with the full feature set. It is a great achievement, putting Cisco MDS 9000 series at the center of customers’ preferences when it comes to both FICON and Fibre Channel switching. Specifically, the new certification adds support for:

◉ IBM Fiber Channel Endpoint Security

◉ CUP Diagnostics

◉ Support for z/OS health checker

◉ 16G and 32G ELW optics for extended reach on dark fiber
