Virtualization Cluster Network in a Nutshell

To be honest, I’m not keen on drawing diagrams, but today I had to spend a couple of hours to sketch this one. It was needed to illustrate Ethernet-links between elements of customer’s physical infrastructure (we’re building a virtualization cluster for them).

As you might know, Apache CloudStack can help you to build a redundant cluster, it means that you can run your virtual instances on 2 virtualization hosts, and when one host needs to be shutdown all virtual instances migrates to another host.

A networking diagram

I hope, this chart could be helpful to people who’re going to set up a networking environment for Apache CloudStack-driven cloud. This drawing seems to be pretty self-descriptive, but feel free to ask any questions if you have some. 🙂
