OpenShift 4 “under the hood”

I have been playing around with Red Hat OpenShift 4.x for the past few months now… It has been a super exciting learning journey. Built on CoreOS: According to me, this is one of the major architectural changes in OpenShift 4.x. and I think it really changed the way platform works…here is how!!!
CoreOS provides “immutability”!!!..what does that even mean…let me explain…while Red Hat CoreOS is built on RHEL components (brining in all the security and control measures)…CoreOS allows you to modify only a few system settings, and make it much easier to manage upgrades & patches. This immutability allows OpenShift do better state management and perform updates based on the latest configurations…basically u don’t update the running code, but push new instants of code, as rolling updates.
so what’s the big deal??..here are the top reasons, why I think its a big deal
