We are looking at the enterprise that is highly virtualized, which looking at the market means VMware or Hyper-v with or KVM and others to a much lessor extent. I believe I’m of the same ilk of the typical traditional VMware enterprise sysadmin. Most Linux admins wouldn’t have too much of a problem installing the solution.

It was good to read this post on Cumulus Linux first impressions by Jeremy Stretch. I’m a fan of Cumulus, but I’m admittedly a Linux guy (see here ) so you might say I’m a bit biased. Jeremy is a “hard-core” networking professional, and so hearing his feedback on Cumulus Linux was, in my opinion, useful.
