Current Trends in DC Networking - Cumulus Networks

Hopefully by now you have heard about Cumulus Networks. If not here is a quick intro.



Cumulus Networks is a full feature Linux distribution for data center (DC) routers and switches. Cumulus Linux is designed to simplify the deployment and automation of DC networks. With that said its not your normal network OS. The configuration and management is more inline with a Debian server than a

Cumulus is a trend?

Yeah the series title might be a little off. Its leaning more toward whats the current buzz or what everyone is talking about.

Next up will be CoreOS and then Docker and Swarm/Kubernetes or whatever. And those have pretty much just as much traction in that space as well.

I guess if I had to justify the title Id say they are part of the whitebox switching trend.

Docker is definitely a trend, and I don't mean the brand of trousers. What concerns me most about Docker is that, one, it is very easy to set up and get going; and, two, any Docker process runs with an account that is also active in the host. You got root in Docker? That means you also got root in the host OS.

Easy setup plus instant root for guys that don't know security equals an east-west nightmare.

Gotcha. Fair.

Yuck.  Seems to be a trend - see if it works first - secure it later when you feel like it or more likely, are absolutely required to in order to sell it. ;P

also the first part of the series is on VxLAN and am demonstrating with multiple vendors since the DC is not a single option anymore. Didnt get VxLAN in this post because it got long.

nice post.

BTW Juniper has now got a container based vSRX. They want you to stitch all your container networking through it. Its probably possible to insert into a devops workflow as well, given that JunOS supports every automation hook under the sun more or less natively (puppet, chef, ansible, python, netconf etc.)

Interesting. Ill have to check that out.

Seems like the same pattern as how vSwitchs went. Instead of using whats built into the hypervisor add vendor x VM and funnel traffic through it.
