Time for another fill-in-the-blanks survey: how many vendors support NETCONF and/or REST API in their data center switches, routers, firewalls and load balancers?
Please help me complete the tables by writing a comment – and do keep in mind that it only counts if it’s documented in a public configuration guide on vendor’s web site.
Also, I’m not aware of any vendor using standard NETMOD YANG models. If someone does, please let me know.
Read more ...Great news everyone. Some of you might have seen that I created a petition to increase the node limit in VIRL. I know there have been discussions within Cisco about the node limit and surely our petition wasn’t the single thing that convinced the VIRL team but I know that they have seen it and I’m proud that we were able to make a difference!
On November 1st the node limit will be increased to 20 nodes for free! That’s right, you get 5 extra nodes for free. There will also be a license upgrade available that gets you to 30 nodes. I’m not sure of the pricing yet for the 30 node limit so I will get back when I get more information on that.
When the community comes together, great things happen! This post on Cisco VIRL will get updated as I get more information. Cisco VIRL will be a much more useful tool now to simulate the CCIE lab and large customer topologies. I tip my hat to the Cisco VIRL team for listening to the community.

Larry Ellison & Co. are serious about IaaS
Kolla provides production-ready containers and deployment tools for operating OpenStack clouds that are scalable, fast, reliable, and upgradable, using community best practices. Kolla entered the OpenStack Big Tent during the Liberty cycle by submitting Kolla to OpenStack technical committee oversight -- enabling the Kolla project and its contributors to have access to community resources such as marketing, technical resources, bi-yearly conference space and voting rights in the OpenStack Technical Committee election.
During the creation of the Kolla mission statement, we agreed as a community not to permit the selection of technology choices in our mission statement. Still: we knew we would choose Docker as our container runtime technology, and Ansible as our orchestration system. We made these choices not only because “that’s what all the cool kids are doing’ -- but also because they solve real technical problems for our problem domain. Docker solves our image management process and Ansible solves our multi-node deployment process. We could have chosen other technologies to solve these problems, but both Docker and Ansible do something orders of magnitude better than competitors: a complete and absolute focus on simplicity coupled with a high degree of capability.
Since a fundamental factor in outcome of Continue reading
Mark Collier, COO of the OpenStack Foundation, takes the stage to kick things off. He starts with a story about meeting new people, learning new things, and sharing OpenStack stories, and encourages attendees to participate in all of these things while they are here at the Summit.
Mark then transitions into a discussion of Liberty (the latest release), and revisits Jonathan Bryce’s discussion of the new organizational model (“the Big Tent”). He specifically calls out Astara and Kuryr as new projects in the Big Tent model. Out of curiosity, he looked at development activity for all the various projects to see which project was the “most active”. It turns out that Neutron was the most active project across all of the various OpenStack projects. According to the user survey last year, 68% were running Neutron. In the most recent user survey, that number climbed to 89%—meaning the vast majority of OpenStack clouds in production are now running Neutron.
So why is networking (and Neutron) so hot right now? Mark believes that this is due to the increasing maturity of software-defined networking and network virtualization. Mark shows data from Crehan Research that states SDN is growing twice as fast as server Continue reading
Today at the OpenStack Summit in Tokyo, Rackspace announced Carina, a new containers-as-a-service offering that is currently in beta. I took a few minutes to sign up for Carina today and work with it for a little while, and here is a quick introduction.
First, if you’re at all unfamiliar with Docker and/or Docker Swarm, have a look at some of these articles off my site. They’ll help provide some baseline knowledge:
A Quick Introduction to Docker
Running a Small Docker Swarm Cluster
I point out these articles because Carina essentially implements hosted Docker Swarm clusters. You can use the Carina CLI tool (as I will in this article) to create one or more clusters, each of which will expose a Docker API endpoint (just like your own homegrown Docker Swarm cluster) against which you can run the Docker client.
Let’s take a quick look. These instructions assume that you’ve already created an account and downloaded the CLI tool from GitHub. I’m assuming you’re running Linux or OS X; the commands for Windows would be quite different than what I’ll show below.
First, you’ll need to set some environmental variables. I prefer to do this in a file that Continue reading
I’ve recently been working on an implementation of VRRP on Linux using Keepalived to provide IP redundancy for some HA Proxy load balancers. I’ve been pleasantly surprised by how simple and fast it is and thought I’d share the details now I understand why it’s the default choice for many. Keepalived has been around for 15 […]
