Yesterday with the announcement of the forthcoming El Capitan supercomputer, which is set to be more powerful than the top 200 supercomputers combined, we got to thinking about a critical issue that is far less attention-capturing than big performance numbers. …

About six months ago, I wrote a post on how to use Cluster API (specifically, the Cluster API Provider for AWS) to establish highly available Kubernetes clusters on AWS. That post was written with Cluster API (CAPI) v1alpha1 in mind. Although the concepts I presented there worked with v1alpha2 (released shortly after that post was written), I thought it might be helpful to revisit the topic with CAPI v1alpha2 specifically in mind. So, with that, here’s how to establish highly available Kubernetes clusters on AWS using CAPI v1alpha2.
By the way, it’s worth pointing out that CAPI is a fast-moving project, and release candidate versions of CAPI v1alpha3 are already available for some providers. Keep that in mind if you decide to start working with CAPI. I will write an updated version of this post for v1alpha3 once it has been out for a little while.
To be sure we’re all speaking the same language, here are some terms/acronyms that I’ll use in this post:

The challenge of managing data is growing faster than the data itself is piling up, and that is bad except for the companies that can create new tools to manage it, either to use internally as the hyperscalers do or to sell to those who cannot fund such development and count on vendors to do it. …

In this week's IPv6 Buzz episode, we talk to Cody Christman about managing networks with IPv6 using the critical transition/translation technology NAT64. We cover why overlapping IPv4 addresses are a big driver for using NAT64, the technical debt of IPv4 NAT, how IPv6 re-simplifies networking, and more.
The post IPv6 Buzz 046: Managing Networks With IPv6 And NAT64 appeared first on Packet Pushers.
Last year we announced that Docker had released a preview of Docker Desktop with WSL 2 integration. We are now pleased to announce that we have completed the work to enable experimental support for Windows Home WSL 2 integration. This means that Windows Insider users on 19040 or higher can now install and use Docker Desktop!
Feedback on this first version of Docker Desktop for Windows Home is welcomed! To get started, you will need to be on Windows Insider Preview build 19040 or higher and install the Docker Desktop Edge 2.2.2.0.
Docker Desktop for WSL 2 Windows Home is a full version of Docker Desktop for Linux container development. It comes with the same feature set as our existing Docker Desktop WSL 2 backend. This gives you:
For the best experience of developing Continue reading

This issue was occuring now because the ARPANET was on the verge of switching from its original NCP protocol, to the TCP/IP protocol which powers what we now call the Internet. With that switch suddenly there would be a multitude of interconnected networks (an ‘Inter... net’) requiring a more ‘hierarchical’ domain system where ARPANET could resolve its own domains while the other networks resolved theirs.
Other networks at the time had great names like “COMSAT”, “CHAOSNET”, “UCLNET” and “INTELPOSTNET” and were maintained by groups of universities and companies all around the US who wanted to be able to communicate, and could afford to lease 56k lines from the phone company and buy the requisite PDP-11s to handle routing.
In the original ARPANET design, a central Network Information Center Continue reading
Engineering students need a computer that is portable, has good CPU speed, lots of memory, great graphics, and is affordable, which means that the laptops useful for most students simply won’t be the best computer for engineering students. Ironically, the laptops that make the best computers for students in engineering are gaming computers.
The reason why gaming laptops tend to be the best computers for engineering students is because the features that make these laptops good for gaming are also the same features that engineering students need, including:
While good gaming computers aren’t cheap, unless someone is a real hardcore gamer, gaming computers can be acquired for between $1,000 and $2,000, which is cheaper and much more portable than a workstation for engineering students. In addition, while great for completing engineering tasks, gaming computers will also allow engineering students to play games, as well as do all the things that regular laptops do.
This allows engineering students to save and share their work, as well as use the Continue reading
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.
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:
