2018 was a great year for NSX with Cloud seeing increased customer traction, strong partnerships established across the board, and a whole host of new features being released throughout the year! While most of our competitors are just starting on their public cloud solution, NSX Cloud is entering its second year of adoption, enabling consistent networking and security across on-premises Datacenter, AWS, and Azure. With NSX-T 2.4, we’re extending our industry-leading capabilities, which will further enable our customers to seamlessly, & consistently manage their public cloud and private cloud workloads.
If you would like to have a refresher on NSX Cloud before we get into the details of what’s new in NSX-T 2.4, here are some pointers to our previous blogs:
At a high level these are some of the key NSX Cloud features that were released in NSX-T 2.4:
Now, let’s Continue reading

Uncomfortable AI: Inc.com has a story asking 16 “uncomfortable” questions that companies should ask about Artificial Intelligence. Among them: Are your reasons for deploying AI in the best long-term interests of humanity? And, how can we ensure that our behavior is inclusive?
Russia attacks fake news: Russian lawmakers have passed two bills, one that outlaws the spreading of fake news, at least as determined by the government there. Another bill makes it illegal to “disrespect” authorities in Russia, the BBC reports. Both bills come with heavy fines, and critics said the laws will limit the ability of journalists to report critical information.
The way forward: Facebook believes encrypted communications and privacy are its future, Recode reports. CEO Mark Zuckerberg outlined the website’s commitments to private messaging in a lengthy blog post.
The way backward: A teen who decided to get himself vaccinated said his mother got misinformation about the dangers of vaccines on Facebook, USA Today says. Ethan Lindenberger, an 18-year-old from Ohio, asked Reddit users if he should get vaccinated as an adult. There’s never misinformation on Reddit, of course.

The Spring 2019 Building Network Automation Solutions course continued with an awesome presentation by David Gee. He started with what you should do before writing a single line of code (identify processes and document them in workflows and sequence diagrams) and covered tons of boring stuff nobody ever wants to talk about.
On Thursday Rachel Traylor continued exploring graphs and their relevance in networking, this time focusing on trees and spanning trees.
The Network Connectivity, Graph Theory, and Reliable Network Design webinar is part of standard ipSpace.net subscription You can access David’s presentation and all other materials of the Building Network Automation Solutions online course with Expert Subscription (assuming you choose this course as part of your subscription).
Efficient synchronisation of state-based CRDTs Enes et al., arXiv’18
CRDTs are a great example of consistency as logical monotonicity. They come in two main variations:
State-based CRDTs look attractive therefore, but over time as the state grows sending the full state every time quickly becomes expensive. That’s where Delta-based CRDTs come in. These send only the delta to the state needed to reconstruct the full state.
Delta-based CRDTs… define delta-mutators that return a delta (
), typically much smaller than the full state of the replica, to be merged with the local state. The same
buffer, to be periodically propagated to remote replicas. Delta-based CRDTs have been adopted in industry as part of the Akka Distributed Data framework and IPFS.
So far so good, but Continue reading
If you follow the IPv6 Maintenance (6man) Working Group of the Internet Engineering Task Force (IETF), you may have noticed the 300+ message email thread on an Internet Draft that was recently published on the “Reaction of Stateless Address Autoconfiguration (SLAAC) to Renumbering Events”. This was prompted by the experiences of developing Best Current Operational Practice on IPv6 prefix assignment for end-users, an activity led by ISOC’s Jan Žorž and published as ripe-690.
SLAAC is used to automatically assign an IPv6 address to a host, but there are a number of scenario where hosts may end up using stale configuration information and thereby leading to interoperability problems.
For example, a typical IPv6 deployment scenario is when a CPE (Customer Premises Equipment) router requests an IPv6 prefix to an ISP via DHCPv6-PD, and advertises a sub-prefix of the leased prefix on the LAN-side via SLAAC.
In such scenarios, if the CPE router crashes and reboots, it may lose all information about the previously leased prefix. Upon reboot, the CPE router may be leased a new prefix that will result in a new sub-prefix being advertised on the LAN-side of the CPE router. As a result, hosts will normally configure addresses for the newly-advertised prefix, Continue reading
Instana is modern, automated application performance management. How do they do this? An agent sits on a host or in a container, and performs continuous real-time discovery and monitoring of all components.

Node.js allows developers to build web services with JavaScript. However, you're on your own when it comes to registering a domain, setting up DNS, managing the server processes, and setting up builds.
There's no reason to manage all these layers on separate platforms. For a site on Cloudflare, these layers can be on a single platform. Serverless technology simplifies developers' lives and reframes our current definition of backend.
In this article I will breeze through a simple example of how converting a former Node server into a Worker untangled a part of my teams’ code base. The conversion to Workers for this example can be found at this PR on Github.
Cloudflare Marketplace hosts a variety of apps, most of which are produced by third party developers, but some are produced by Cloudflare employees.
The Spotify app is one of those apps that was written by the Cloudflare apps team. This app requires an OAuth flow with Spotify to retrieve the user’s token and gather the playlist, artists, other Spotify profile specific information. While Cloudflare manages the OAuth authentication portion, the app owner - in this case Cloudflare Apps - manages the small integration service that uses the Continue reading
