Cloud Networking Transformation Ahead

Networking is undergoing a metamorphosis. Today’s operations are challenged to cope with the DevOps, NetOps, SecOps and CloudOps models that need consistent operations control. Why should enterprises care? How do you cope with decades of legacy and is change possible? Arista believes that the networking world is at the cusp of a transformation, significantly facilitated by the agile, dynamic and economic network models of the public cloud providers. They have proven the elegance of simple yet scalable designs that transform siloed networks for the data center, core, campus or branch PINs (Places in the Network) into east west PICs(Places in the Cloud). This new paradigm is a far cry from the traditional siloed network architectures that required applications to be assigned to specific servers or storage, causing fixed-function rigidity. Agility and high availability are pivotal foundations to building the new PICs.

Should I Go with VXLAN or MLAG with STP?

TL&DR: It’s 2020, and VXLAN with EVPN is all the rage. Thank you, you can stop reading.

On a more serious note, I got this questions from an Johannes Spanier after he read my do we need complex data center switches for NSX underlay blog post:

Would you agree that for smaller NSX designs (~100 hypervisors) a much simpler Layer2 based access-distribution design with MLAGs is feasible? One would have two distribution switches and redundant access switches MLAGed together.

I would still prefer VXLAN for a number of reasons:

Rust: Constants, Variables, and Mutability – Oh My!

In the last post I wrote about my journey from Python to Go as my primary language, and how I am now exploring Rust. This will be the first in a series of posts on Rust, mostly written from this perspective. I realize not everyone is going to Rust from Go, but that’s my perspective, and it will be impossible to keep this perspective from showing through and making comparisons between Rust and Go or Python.

A requirements spec for voting

In software development, we start with a "requirements specification" defining what the software is supposed to do. Voting machine security is often in the news, with suspicion the Russians are trying to subvert our elections. Would blockchain or mobile phone voting work? I don't know. These things have tradeoffs that may or may not work, depending upon what the requirements are. I haven't seen the requirements written down anywhere. So I thought I'd write some.


One requirement is that the results of an election must seem legitimate. That's why responsible candidates have a "concession speech" when they lose. When John McCain lost the election to Barack Obama, he started his speech with:

"My friends, we have come to the end of a long journey. The American people have spoken, and they have spoken clearly. A little while ago, I had the honor of calling Sen. Barack Obama — to congratulate him on being elected the next president of the country that we both love."

This was important. Many of his supporters were pointing out irregularities in various states, wanting to continue the fight. But there are always irregularities, or things that look like irregularities. In every election, if a Continue reading

Use TheGreenBow VPN Client to Connect with VyOS

The site-to-site Virtual Private Networks (VPN) connect two or more remote locations. Thanks to it, computers located inside locations can communicate securely over the public Internet as they were located on the same private network. This is accomplished by tunnels that interconnect remote locations. Tunnels add extra layer security, encrypting user traffic carried inside tunnels. […]

Are All Networks Created Equal?

It’s not illogical to argue that since we all use the same networking technologies that all networks are essentially the same. Routing protocols, layer two technologies, and overlays all behave the same whether they are run in SOHO, enterprise, or service provider environments. That being said, it feels like there can be worlds of difference between the application of these technologies in different environments. In this episode Nick Buraglio, Kevin Myers, and I discuss just how interchangeable these technologies are and why it feels like engineers who work on the same technologies can feel worlds apart when their paths intersect.

Internet Society community members,

Due to concerns associated with the COVID-19 coronavirus, including the possibility of quarantines and other travel restrictions, the Internet Society Board of Trustees has decided to hold its meeting on 13-14 March, 2020, as a virtual meeting instead of a physical meeting in Cancun, Mexico. This board meeting was originally planned to follow the ICANN 67 meeting in Cancun, which was also changed to a virtual meeting.

The agenda and remote participation information will be published to https://www.internetsociety.org/board-of-trustees/meetings/ within the next few days.
