[CentOS] Are linux distros redundant?

I just realised that I haven't touched a centos/redhat machine in more than
a couple of years. Everything I do now is Kubernetes based or using cloud
services (or k8s cloud services).

What about it listeroons? Is your fleet of centos boxes ever expanding or
are you just taking care of a single java 6 jboss application that takes
care of the companies widget stocks?

How are your jobs changing?

Cheers,

Andrew
