I've been using Redhat/CentOS as long as they have existed. I recently started converting all my VPS nodes to Alpine Linux for these reasons.

I don't imagine that happening at work any time soon. Our tooling is too heavily entrenched in CentOS. We've looked at CoreOS, but have a long way to go to containerize hundreds of chef roles. The containers are using CentOS; and in some cases, Alpine as the base.
