Chipping Away at S/4 HANA Migration challenges

Gaining competitive advantage with digital transformation is a balancing act of value and cost.  Delivering incremental value at a high cost is not advantageous, and S/4 HANA business process migration can be expensive.

Cisco, Intel and SAP have partnered to deliver a solution that increases the value of the S/4 HANA migration while decreasing the cost, and potentially reducing the migration challenges.  We achieved by incorporating the Intel Optane Datacenter Persistent Memory into Cisco UCS solutions for SAP HANA.

Intel Optane Datacenter Persistent Memory and the SAP Value

The Intel Optane DC PMEM is a persistent memory device that sits directly on the memory bus of the server system board sharing the memory space with the existing dynamic memory.  This new device retains the data stored when the server power is turned off and is immediately available for usage when the server power is restored, and the SAP HANA database restarted.  The new persistent memory is available in three memory sizes; 128G DIMMs, 256G DIMMs and 512G DIMMs.

This new combination of dynamic memory and persistent memory provides three interrelated benefits which result in reduced total cost of ownership without impacting the in-memory performance.

Value #1: Realizing Real Cost Savings

First, the Intel Optane DC PMEM has a lower price per TB than industry standard dynamic memory.  A direct comparison of the 128G DRAM DIMM and the 128G PMEM DIMM results in an estimated 50% cost reduction when replacing DRAM with PMEM.  The value- a direct 25% reduction in the SAP HANA server acquisition cost.  This is a very real savings when you consider almost all S/4 HANA migrations have at least 3 SAP HANA servers.  This price comparison will vary as the volatile price of memory changes.

Value #2: Increased memory capacity without excessive costs

The Optane DC PMEM are available in larger capacity sizes ranging from 128G to 512G resulting in larger capacity without significantly increasing cost.  It is now possible to build a 4-socket UCS B480 server with 6T of Optane PMEM SAP HANA data tables space.  Before Optane PMEM this size of data table space required an expensive 8-socket server fully loaded with 96 128G DRAM DIMMs.  And the interesting fact is this increased capacity 4-socket server is almost the same price as a traditional 4-socket DRAM-only server with only 3T of SAP HANA data table capacity.  12T of SAP HANA data tables can also be supported on a 4S system for customers with deep pockets.

Value #3: Reduce planned downtime

A traditional 6T SAP HANA database can take over 65 minutes or more to reload into memory significantly increasing the time needed for planned downtimes.  The Optane PMEM saves the data in the memory devices and presents the data immediately when SAP HANA is restarted.  This decreases the restart time to well below the 65 minutes, many times decreasing the restart time by a factor of 12 or more.  System recovery for planned downtime can be significantly reduced resulting in less time needed for productive system maintenance.

Special S/4 HANA and BW/4 HANA Server Opportunity

Deciding when to migrate your workload to SAP HANA or to refresh your existing landscape is a difficult decision.  Cisco and Intel are announcing a short-term program to make that decision a little easier.  Cisco has created four unique SAP HANA server products that provide even more price value than just the Optane pricing.  These 4 servers enjoy not only the 25% cost savings associated with Optane PMEM pricing, but a nearly additional 20% special saving to help reduce the cost of SAP HANA migration and refresh programs.  Combine this SAP HANA server with the newly enabled S/4 HANA and BW/HANA Landscape bundles to create an end to end landscape solution for your S/4 HANA or BW/4 HANA migration program.

Migrating to SAP S/4 HANA presents challenges and risks.  Confidently accelerate SAP modernization and migration efforts with these new Cisco® SAP solution packages. Fast-track your SAP HANA andS/4 HANA projects by applying your realized CapEx infrastructure savings toward SAP migration services.

Now you can easily test drive Intel Optane DC persistent memory and discover Optane’s SAP HANA value.

Where’s my Endpoint?

Is there a way to know what endpoints are alive within your data center at this moment? Is it possible to continuously monitor the life of every endpoint – be it a Virtual Machine (VM), a physical host or even a container ? Enter Endpoint Locator or EPL!

With DCNM available as a manager for data center fabrics, we decided to incorporate EPL directly into DCNM. EPL has been shipping as a preview feature in DCNM since November 2016. General availability of this feature is now available with the DCNM 10.2(1) May 2017 release.

For a VXLAN BGP EVPN based data center fabric, Endpoint Locator provides near real-time tracking of every endpoint. Events such as endpoint coming up, endpoint going down, or endpoint move are now visible with a few simple clicks. EPL supports all kinds of endpoints, be it IPv4, IPv6 or Dual-Stack. In fact, EPL can literally locate anything with a MAC or IP address.

To provide context to the detected endpoint itself, additional information is gathered and correlated, resulting in a multitude of data points at your fingertips. Find your endpoints physical location with the reference to the associated switch and connected physical interface. Add in logical information such as VLAN, VRF or VNIs. The ease of access and visibility of such information within the data center is unprecedented for data center fabrics.

Once EPL is enabled via a simple wizard, it starts gathering information about existing endpoints and from then onward, all network events associated with the endpoint will be tracked.

Apart from a live endpoint dashboard, EPL also displays endpoint historical information for a time period specified in absolute or relative data ranges. The endpoints can be filtered by a variety of parameters including the VRF, network identifier, switch name, etc. Any search results are available for instant download.

In addition to the dashboard, EPL offers a set of Operational and Exploratory analytics views that are based on the collected endpoint data.

◉ Network Historical View – Displays daily historical information about endpoints, networks, and VRFs in terms of currently active endpoints, endpoint additions & deletions.

◉ Operational Heatmap – Displays holistic information on all the operations that have been occurring in the fabric on an hourly basis.

◉ Endpoint Life – Displays a timeline of a particular endpoint throughout its entire existence within the fabric showing where the endpoint was located and where it has moved.

Stay tuned for more innovations like these which drive operational simplicity and visibility into data center fabrics using DCNM.

A Special acknowledgement to Shyam Kapadia for being the primary development lead for EPL; our journey started with an innocent break room conversation about a customer problem with respect to workload visibility.

Do the Impossible: Deliver the Best Collaboration Experience and Secure Sensitive Data with Cisco’s Extended Secur …

Security is Paramount, and Cisco Webex is the Market Leader

Security is critical for any collaboration deployment because employees inevitably share sensitive data and intellectual property. Building out security is hard as it’s not a standalone feature that can be built in isolation. It is a platform-level capability that needs to be designed for every component and every feature support must comply with it to be effective.

Cisco has security in its DNA from the network to devices to the cloud. Cisco Webex was architected with a 360 approach to security. We looked at the full attack surface and possible threat vectors to build controls and mitigations while providing the best user experience, and enabling users to securely collaborate with users outside of their companies and support their personal devices.

Customer Challenges

Users are increasingly using collaboration tools to do their job – and it often involves sensitive data – whether it’s intellectual property, personally identifying information or financial information. Line of business executives and IT administrators are concerned about data loss especially when their users are collaborating externally. As an open platform, Webex has an events API and one of the largest compliance and Data Loss Prevention (DLP) partner ecosystems in the industry to address these concerns.

However, many of our customers do not have a central DLP solution deployed and this stalls rollout of modern collaboration tools. Even if some customers deploy these tools, IT admins end up blocking collaboration with external users and use of personal devices in order to mitigate these data loss risks.

Not only does this impact employee adoption of these tools, it increases data loss and malware exposure as users start using non-sanctioned consumer collaboration apps to get the job done.

Extended Security Pack Solution

I am thrilled to announce a new Collaboration Flex add-on offer – the Cisco Webex Control Hub Extended Security Pack – a Cisco-on-Cisco best of breed solution to this customer problem that packages full functionality Cisco Cloudlock for Webex Teams with native Webex anti-malware capabilities powered by Cisco Talos ClamAV in Webex Cloud.

The new Extended Security Pack is available now and enables our customers to safely and securely rollout modern collaboration with best user experience.

Cloudlock DLP policies follow your employees even when they collaborate with external users. And our anti-malware solution will block infected files from being downloaded and malicious URLs will not be expanded and clearly marked for end-users.

Peace of Mind Through Industry Leading Webex Teams Security

We firmly believe that every customer is different and there is “no one size fits all” security model, and therefore IT Admins can choose Webex Control Hub policies to match Webex security to their risk profile. We are announcing new controls to manage 3rd party integrations like JIRA, Box, and Smartsheet into Webex. The ability to manage bots and whitelist external domains for collaboration will be available in October. In addition, Control Hub now supports active directory groups for automatic license assignment based on your geography, role or other criteria.

We are very excited to partner with ThetaLake to support AI-based archiving, eDiscovery, and supervision for Webex Meetings recordings with automated detection of compliance risks in audio and visual content, including screenshares.

The new Control Hub search and extraction tool is available now and will support large lawsuits and investigations by allowing hundreds of users in one query. In addition, a simple EML export mechanism will allow faster integration into eDiscovery tools and quick viewing of extracted content for internal investigations.

Trust and Protection You Can Count on 

Webex has tight controls on privacy and personal identifiable information and supports various cross-border frameworks and is GDPR compliant. ISO 27018 is the first certification to focus on privacy and PII controls and Webex Meetings and Teams have passed the ISO27018 audit.

Webex is adding new built-in mobile application management (MAM) capabilities to set up a timeout for Teams mobile client with application PIN lock and an ability to block notifications with message content on lock screen. In addition, we are proud to announce a common mechanism for customers to wrap all Webex mobiles apps (Meetings, Teams and Jabber) using their favorite MAM SDK starting October 2019.

The 3 W’s in Zero Trust Security

Picture this scenario: you are a security guard at an office building. Today you are looking after a restricted area. A person you’ve never seen before walks straight past you into one of the rooms. Would you stop them or would you just assume they are allowed to be there?

In a physical world, trust is most commonly based on who you are, not where you are. A savvy security guard would ask you for your ID before allowing you in. Virtually, though, the situation is different: being in the right place is often enough. If you are inside of a company’s network perimeter, it is often assumed you have the right to be there. You gain access to the same data and tools that any other trusted user would. It’s clear that such an approach is no longer enough.

Zero trust security comes in as an alternative model, more in line with the current threat landscape.  It is based on the principle of “always check, never trust“, originally introduced by Forrester. It takes into account 3 main factors:

◉ Workforce: Employees are at risk of identity theft, which is one of the most widespread types of fraud today.

◉ Workload: New vulnerabilities in applications and their improper management open highways for cybercriminals.

◉ Workplace: With more and more connected devices, the workspace has extended far beyond the four walls of you company building.

Moving from a perimeter model to Zero Trust means assessing, adapting and implementing new security policies that address threats in a constantly changing environment. In this trust-centric approach access is granted to users and devices, not a network.

This means that policies now need to be calculated based on a vast number of data sources. All network activities must be continuously taken into account. Any indications of compromise or changes in the behaviour of apps, users and devices must be examined, validated and receive immediate responses.

How to apply a Zero Trust model

Cisco’s practical approach to Zero Trust includes six important steps.

1. Establish levels of trust for users and user devices (identity verification with multi-factor authentication and device status, which must be compliant and properly updated)

2. Establish levels of reliability for IoT and/or workloads (profile and baseline)

3. Establish SD perimeters to control access to the application (authorised access)

4. Establish SD perimeters to control access to the network (segmentation and micro-segmentation)

5. Automate the adaptive policy using normalisation (network, data centre and cloud)

6. Automate the adaptive policy using the response to threats (adapt the level of trust)

Zero Trust Security involves people, processes and technology in its adoption. It can provide a roadmap for a truly efficient and automated security infrastructure.

Ransomware in Education: How to use your Network to Stay Ahead of Attacks

Educational institution systems store a large amount of sensitive data, including student and employee records. They rely heavily on these systems for day-to-day operations. So any disruption or loss of access can be a game changer. But these same institutions also often have tight budgets and can’t afford to employ large security teams. That’s one reason they’re perceived as easy and lucrative targets by online adversaries.

A typical response may be to deploy multiple security technologies to block threats from entering your organization at various attack vectors, and you should continue to do so. However, just relying on these techniques isn’t enough since 100% prevention is not possible in today’s complex threat landscape. That’s where continuous monitoring of your network’s behavior comes in. By using this approach, you can help detect and respond to a ransomware attack more quickly and effectively.

How to stay ahead of cyber threats

Your network is a source-of-truth of every activity – normal or malicious. Adversaries must use your network in order to carry out their malicious objectives. Because of this, collecting and analyzing your network telemetry is an effective way of detecting advanced threats, like ransomware. Here’s how it helps you.

◉ Detect threats early by pinpointing suspicious behavior. Ransomware attacks are generally initiated through methods like a phishing email or exploitation of a vulnerability. It might involve behavior such as port scanning, command-and-control (C&C) communication back to the attacker network, etc. Whatever means the attackers use, the activity touches the network. By using behavioral modeling, this kind of activity can be easily detected. You can also create custom security policy alerts to detect restricted communications such as use of SMB protocol, or access to sensitive data servers from outside the network. So even if the ransomware is an unknown strain and has infected the organization, the anomalous behavior will give the attackers away.

◉ Correlate local alerts to global campaigns. Attackers often reuse ransomware strains to infiltrate multiple organizations. An effective network security analytics solution is powered by industry-leading threat intelligence that has the knowledge of all the malicious domains, servers, campaigns, and other indicators of compromise. Using multiple analytical techniques like statistical modeling and machine learning, billions of network sessions within your organization can be processed and correlated to global campaigns, in order to pinpoint attacks and then quickly remediate.

◉ Perform forensic analysis for incident response. Your organization has been infected, and you have been immediately notified through alerts of the ransomware attack. Now what? Time is of the essence and your security teams need to answer questions like what machines have been infected, what was the source of the attack, and where are communications occurring? Because you have a record of every network communication, you can begin from the alert and investigate back in time to conduct a thorough forensic analysis to answer those questions and contain the ransomware.

Industry-leading network visibility and security analytics

The capabilities described above are offered by Cisco’s network traffic analysis solution, called Cisco Stealthwatch. It provides enterprise-wide visibility, from the private network to the public cloud, and applies advanced security analytics to detect and respond to threats in real-time.

By using a combination of behavioral modeling, machine learning, and global threat intelligence, Stealthwatch can quickly (and with high confidence) detect threats such as:

◉ C&C attacks
◉ Ransomware
◉ DDoS attacks
◉ Illicit cryptomining
◉ Unknown malware
◉ Insider threats.

With a single, agentless solution, you get comprehensive threat monitoring across your data center, branch, endpoint, and cloud. Plus, it can also analyze encrypted traffic for threats, without any decryption, using our proprietary Encrypted Traffic Analytics technology.

Stealthwatch can detect ransomware hiding in encrypted traffic, and can also correlate it to global campaigns like WannaCry.

By deploying Stealthwatch, you can turn your network into a “threat sensor” by simply collecting telemetry such as NetFlow. And there is no need to deploy multiple agents. Stealthwatch can be deployed easily. Best of all, it scales automatically with your infrastructure, growing as your needs grow.

Using Automation with your Security Products

For network engineers, automation is changing the way we interact with the network devices that are a key part of our responsibilities. This is a fundamental change in the way that we’re used to controlling these devices. And if you’re a network engineer, it’s natural that you might be hesitant to use automation because you think it might reduce the number of engineers required to maintain devices. But I challenge you to think first about the increased efficiency that it will provide.

Three reasons to embrace network automation

It’s important to remember that network automation is not just another “flavor of the month” but the future of our industry. So now is a prime opportunity for you to lead rather than follow. I suggest you embrace it and by doing so become a better engineer. And as you begin, understand that there are three key reasons you should implement network automation:

◉ To reduce configuration errors. Automating the repetitive configurations used in the network will help reduce your error rates caused by manually configuring the devices.

◉ Improve network management. Many processes you perform regularly on your devices may not get done, or experience a delay, due to the manual nature of the tasks. Automating them is a great way to ensure they get done.

◉ Free up your IT Staff for critical tasks. By using automation for less critical tasks, it allows your team to focus on performing the critical tasks that ensure the network is running at peak efficiency.

Four tools for network automation

Now, let’s look at four tools you can use for automating your network:

◉ Python is quickly becoming one of the most used languages for automation. It’s a much more human readable language.

◉ Github is a great repository for code used for automation. Plus, there are numerous Cisco supported repositories on Github. So you can download these to jump start your automation journey.

◉ Postman is a great tool to get you going with interacting with your network devices.

◉ Ansible is a great network automation platform.

Cisco DevNet and network automation

Next we need to look to Cisco DevNet. Cisco has announced new certifications around network automation, and they’ve put countless hours into developing a world class training and development environment:

Plus, they continually host special events to help you grow your skills.

A closer look at the Security Dev Center

By visiting the site, you can check out all the API’s for the Cisco Security Products. You can also leverage the page as a long-term learning resource, and take a deeper dive on topics you’re interested in as time allows. Here you can learn about a variety of trending issues, like controlling threats with Firepower, Cisco’s NGFW, or automating your security with pxGrid.

Enterprise Networking in 2020: 5 Trends to Watch in Wireless, SD-WAN, More

Networking isn’t what it used to be. A few years ago, the epicenter of networking began to move. It shifted from company-owned datacenters, out to the cloud. For users, the focus of networking moved from computers connected with wires, to mobile devices connected over the air. These fundamental shifts, in where business processes run and how they’re accessed, is changing how we connect our locations together, how we think about security, the economics of networking, and what we ask of the people who take care of them.

So it is going to be an exciting year. Here’s how:

Wireless: It’s Wi-Fi, It’s 5G. It’s Both.

In 2020, Wi-Fi 6 will enter the enterprise, through the employee door and through enterprise access point refreshes. 5G will also appear, although in 2020, it will be mostly for consumers.

The latest smartphones from Apple, Samsung, and other manufacturers are Wi-Fi 6 enabled, and Wi-Fi 6 access points are currently shipping to businesses and consumers. 5G phones are not yet in wide circulation, although that will begin to change in 2020. We project that through 2020 more people will be using Wi-Fi 6 than 5G.

2020 will also see the beginning of a big improvement in how people use Wi-Fi networks. The growth of the OpenRoaming project will make joining participating Wi-Fi networks as easy as using a cell phone in a new town: Users won’t have to think about it.

While “5G” service will roll out in 2020 (some is already switched on today), almost none of it will be the ultra-high speed connectivity that we have been promised or that we will see in future years. With 5G unable to deliver on that promise initially, we will see a lot of high-speed wireless traffic offloaded to Wi-Fi networks.

2020 will also see the adoption of new frequency bands, including the beginning of the rollout of “millimeter wave” (24Ghz to 100Ghz) spectrum for ultra-fast, but short-range 5G; and of CBRS, at about 3.5Ghz, which may lead to the creation of new private networks that use LTE and 5G technology, especially for IoT applications. We will also see continued progress in opening up the 6 GHz range for unlicensed Wi-Fi usage in the United States and the rest of world.

Eventually, having even more pervasive, high-speed, secure wireless connectivity will open up new kinds of business opportunities in all industries, from healthcare to transportation. In combination with the improved performance of both Wi-Fi 6 and (eventually) 5G, we are in for a large – and long-lived – period of innovation in access networking.

The Network as Intelligent Sensor

Businesses have started to use their networks for more than data transmission. Now they’re being used to sense their environments as well. This is going to have big impacts on business – not just for network operators, but directly to the bottom line as well.

With software that is able to profile and classify the devices, end points, and applications (even when they are sending fully encrypted data), the network will be able to place the devices into virtual networks automatically, enable the correct rule set to protect those devices, and eventually identify security issues extremely quickly. Ultimately, systems will be able to remediate issues on their own, or at least file their own help desk tickets. This becomes increasingly important as networks grow increasingly complex.

Wireless networking equipment can also collect data on how people and things move through and use physical spaces – for example, IoT devices in a business; or medical devices in a hospital. That data can directly help facility owners optimize their physical spaces, for productivity, ease of navigation, or even to improve retail sales. These are capabilities that have been rolling out in 2019, but as business execs become aware of the power of this location data, the use of this technology will begin to snowball.

SD-WAN Plans Solidify in 2020

The workplace is becoming virtual, not physical. Businesses now hire talent wherever it is, and these dispersed employees are connecting to increasing numbers of cloud services. This dispersal of connectivity – the growth of multicloud networking – will force many businesses to re-tool their networks in favor of SD-WAN technology. IDC research shows that almost 95% of the enterprises they surveyed expect to be using SD-WAN within 24 months.

Meanwhile the large cloud service providers, like Amazon, Microsoft, and Google are connecting to networking companies (like Cisco), to forge deep partnership links between networking stacks and services.

When it comes to their own WAN solutions, each enterprise is different. Some enterprises, looking for security solutions that align with compliance regulations, need on-premise security. Smaller businesses often want their security solutions in the cloud. Many businesses will need hybrid solutions that combine elements of traditional on-premise control for compliance, with cloud-based solutions for flexibility and agility. Security, and workloads, have to be installed where they meet the needs of the business.

This is going to lead to a growth in business for managed service providers (MSPs), many more of which will begin to offer SD-WAN as a service. We expect MSPs to grow at about double the rate of the SD-WAN market itself, in line with IDC’s predictions. We also expect that MSPs will begin to hyper-specialize, by industry and network size.

Multidomain Needs Spur Controller-Based Integration

The intent based networking model that enterprises began adopting in 2019 is making network management more straightforward by absorbing the complexities of the network. However, networking systems are made up of multiple networks themselves (for example, campus networks and WANs), as well as domains of technology that are traditionally managed in their own domains (for example, security). For better management, agility, and especially for security, these multiple domains need to work together. Each domain’s controller needs to work in a coordinated manner to enable automation, analytics and security across the various domains.

Increasing network complexity fuels adoption of multidomain technologies.

The next generation of controller-first architectures for network fabrics allow the unified management of loosely-coupled systems using APIs and defined data structures for inter-device and inter-domain communication. With the way networks are changing, there is no other solution to keep ahead of system growth and complexity.

From Network Engineer to Network Programmer

The standard way that network operators work – provisioning network equipment using command-line interfaces like CLI – is nearing the end of the line. Today, intent-based networking lets us tell the network what we want it to do, and leave the individual device configuration to the larger system itself. We can also now program our updates, rollouts, and changes using centralized networking controllers, again not working directly with devices or their own unique interfaces. But new networks run by APIs require programming skills to manage. Code is the resource behind the creation of new business solutions.

If maximizing the value of these controllers means getting up to speed with programming them, there’s a big opportunity for the people who get ahead of this trend. But it will not be an easy change. Retraining yourself (or your team) is expensive, and not everyone will adapt to the new order. For those that do, the benefits are big. Network operators will be closer to the businesses they work for, able to better help businesses achieve their digital transformations. The speed and agility they gain thanks to having a programmable network, plus telemetry and analytics, opens up vast new opportunities.

It remains critical for individuals to validate their proficiency with new infrastructure and network engineering concepts. With training, network operators will be able to stay closer to the businesses they work for, providing value beyond maintenance and support. Networks in 2020 will become even more central to how businesses function. As always, CEOs will direct resources into infrastructure projects that directly generate revenue.       

2020 Will be Transformative

Together, new capabilities will make networks into even more important business assets, and companies will leverage them in ways that we have not imagined.

We just finished surveying over 2,000 network executives and operators on the future of networking.
