The rise of the disaggregated network operating system (NOS) marches on: this time, it’s Big Switch Networks announcing expanded hardware support in Open Network Linux (ONL) , upon which its own NOS is based. I use OTR with Adium on OS X, and OTR with Pidgin on my Fedora Linux laptop.). Virtualization. Servers/Hardware.

Romain Decker has an “under the hood” look at the VMware NSX load balancer. This graphical summary of the AWS Application Load Balancer (ALB) is pretty handy. This version introduces vulnerability scanning (leveraging the Clair project ), and Henry Zhang has a blog post with more details.

Via Ivan Pepelnjak, I was pointed to Jon Langemak’s in-depth discussion of working with Linux VRFs. I read a couple of Cilium-related blog posts recently that may be useful. The first is a post on Cilium and F5 load balancer integration , while the second discusses implementing Kubernetes network policies with Cilium and Linkerd.

Some folks from Nicira (now part of VMware) recently published a blog post discussing the OVSDB IETF draft (see here ). Erik Smith, notably known for his outstanding posts on storage and FCoE, takes a stab at describing some of the differences between SDN and network virtualization in this post. Virtualization. Networking.

High speed low latency networks now allow us to add these nodes anywhere in a cloud infrastructure and configure them under existing load balancers. OpenStack is a proven Infrastructure as a Service solution that has the ability to scale virtual machines based on the metrics of existing nodes. Automated Kubernetes Deployments.

Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). and their product (VirTool Network Analyzer) is aimed at providing some operational visibility into OpenStack virtual networks. Dusty Mabe has a multi-part blog series on Atomic Host. Virtualization.

“My favorite parts about Linux Academy are the practical lab sessions and access to playground servers, this is just next level.” It provides a huge range of virtual machines suitable for general purpose and specialized on-demand compute tasks. First, you will create and configure an Application Load Balancer.

Open Virtual Network (OVN) is really ramping up and getting lots of attention, which I personally think is absolutely well-deserved. See the official Docker blog post for more information (and rest assured I’ll have some blog posts up on some of this stuff as well). Virtualization. Welcome to Technology Short Take #56!

Ray Budavari—who is an absolutely fantastic NSX resource—has a blog post up on the integration between VMware NSX and vRealize Automation. If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. Virtualization. This one is a bit older (refers to NSX 6.1
