There are lots of reasons why we have a tendency to stick to what we know best, but when new solutions present themselves, as the decision makers, we have to make sure we’re still bringing the best solution to our business and our customers. This post will highlight the virtues of building an IP based fabric of point to point routed links arranged in a Clos spine and leaf topology and why it is superior to legacy layer 2 hierarchical designs in the data center.
It’s not only possible, but far easier to build, maintain and operate a pure IP based fabric than you might think. The secret is that by pushing layer 2 broadcast domains as far out to the edges as possible, the data center network can be simpler, more reliable and easier to scale. For context, consider the existing layer 2 hierarchical model illustrated below:
This design depends heavily on MLAG. The peer link is compulsory between two switches providing an MLAG. An individual link failure on the peer link would be more consequential than any of the other links. Ideally, we try to avoid linchpin situations like this. This design does provide redundancy, but depending on Continue reading
Howdy… if you have managed to check-in and get your AWS re:Invent pass, congratulations! Looks like running between AWS sessions across hotels in Las Vegas is the new Turkey Trot – welcome to the “Cloud First” world! Amongst all the craziness, we just wanted to take a moment and send a note to you from the NSX team.
As all of you know, NSX Cloud supports Azure and AWS since our latest NSX release – NSX 2.3. NSX Cloud will be showcased at the NSX demo pod at the VMware booth (Booth#2201) at AWS re:Invent (Sands Expo, Venetian). Our product experts are looking forward to meeting customers, answering product and use-case questions, and showcasing demos.
During the event, there will be multiple theatre presentations on NSX Cloud with a lot of swags to grab. For customer/partner meetings on NSX Cloud during the event, please reach out to the PM team (Percy Wadia, Shiva Somasundaram and Amol Tipnis). If you would like to take a look at all the Past Blogs and YouTube Videos on NSX Cloud, we have got it sorted for you.
The excitement is going to continue even after re:Invent as we will Continue reading
We are excited to announce that NSX Cloud, the VMware networking and security solution for AWS-native applications and hybrid-cloud, is now available in the AWS Solution Space! AWS created the Solution Space as a place for AWS Partner Network (APN) Technology Partners to showcase customer-ready solutions that combine AWS services with partner technologies and, optionally, consulting offers from APN consulting Partners. This is an especially notable milestone for NSX Cloud because it will be one of the first offerings in the Networking category for Solution Space.
NSX Cloud will be featured at AWS re:Invent this week, so be sure to stop by our theater sessions at the VMware booth (#2201) on Tuesday at 3:30pm or Thursday at 11:30am. We look forward to seeing you there, and are giving away an exciting prize to a lucky winner at each session!
NSX Cloud is an extension of VMware’s NSX Data Center technology that brings the NSX networking and security framework to cloud-native applications in AWS. With NSX Cloud, IT administrators can apply the exact same networking and security policies they use in the data center to AWS-native applications, and they can manage those applications through the same interface Continue reading
In this briefing, Dell EMC focused on their Cyber Recovery 18.1 product. You might be thinking, “Oh, another backup product. I already have one of those.” Sort of. Cyber Recovery is more than simply backup, and it’s more than what a decent disaster recovery plan gets you. The Cyber Recovery Vault is an orchestrated Data Domain storage platform that provides an isolated copy of known good data that can be used to recover from a security breach.

Within GKE, Istio will collect telemetry about a running container and send that information to either Stackdriver or Prometheus to allow an organization to monitor the health of that container.
The research firm MTN Consulting said that Alibaba’s cloud computing business is rapidly becoming the group's “most ambitious venture,” as it boosts its overseas investments and refocuses on R&D.
A common complaint I hear among network engineers is that the lessons and techniques used by truly huge scale networks simply are not applicable to more “standard scale” networks. The key point, however, is balance—to look for the ideas and concepts that are interesting and at least somewhat novel, and then see how they might be applied to products and systems in all networks. Learning concepts can help you understand design patterns you might encounter almost anywhere. One recent paper, for instance, details Andromeda, a large scale networking system designed and operated by Google, one of the few truly huge networks in the world—
Andromeda is designed around a flexible hierarchy of flow processing paths. Flows are mapped to a programming path dynamically based on feature and performance requirements.
While the paper describes the general compute environment, and the forwarding process on individual nodes, the most interesting part from a network engineering perspective is hoverboard. While this concept behind hoverboard has been implemented in previous systems, it is usually hidden under the covers of a vertically integrated system, and therefore not normally something you see the inner workings of. To understand hoverboard, you have to begin with a little theory Continue reading

Government officials are fearful that telecom providers using Huawei gear in other countries will be vulnerable to spying.
In this interview, Srinivas opens up about how data analytics has changed the network operations function, how IoT devices will impact networks, and how analytics can help boost network performance.
I had the opportunity to sit in on a great briefing from Gremlin the other day about chaos engineering. Ken Nalbone (@KenNalbone) has a great review of their software and approach to things here. The more time I spent thinking about chaos engineering and IT, the more I realized that it has more in common with Murphy’s Law that we realize.
If there’s more than one way to do a job and one of those ways will end in disaster, then somebody will do it that way. – Edward Murphy
Anything that can go wrong will go wrong. – Major John Paul Stapp
We live by the adage of Murphy’s Law in IT. Anything that can go wrong will go wrong. And usually it goes wrong at the worst possible time. Database query functions will go wrong when you need them the most. And usually at the height of something like Amazon Prime Day. Data center outages only seem to happen at 4 am on a Sunday during a holiday.
But why do things go wrong like this? Is it because the universe just has it out for IT people? Are we Continue reading
BGP Route Reflection solves a fundamental problem in iBGP operation but introduces some tradeoffs to consider when implementing. In this Network Collective short take, Russ details these tradeoffs and some potential ways to mitigate unintended consequences.

France tackles the Internet: The French government has been making news in recent days for examining ways to regulate the Internet. Its parliament has passed a controversial new law that would allow judges to order the immediate removal of online articles they deem to be fake news, Euronews.com reports. Critics warned the law, which allows for jail sentences for fake news creators, could lead to censorship.
Regulation or autocracy? French President Emmanuel Macron pushed the fake news law, and he also called for more government regulation of the Internet at a recent Internet Governance Forum in Paris. Macron called for international cooperation on Internet issues, as a way to tame disinformation, with CFR.org suggesting governments must adapt to fight modern problems. But TechDirt suggested Macron was acting like an autocrat in his call for more regulation.
Broadband plan MIA: Canada’s government, meanwhile, has “no plan” to bring broadband to rural and remote areas, a government auditor said. Canada’s rural broadband efforts so far have led to “a series of moving targets, lofty proclamations, piecemeal programs, and ultimately big letdowns,” Motherboard says.
