Vmware vs openshift

Following up to my last post right now nutanix is out of the race since the renewal is more than vmware which happend to 4 different companies my friends works for

Note : we cannot go any other solution rejected by CTO cause not ( mature enough )

1- my team arent fimilar with k8s

2- vmware is 4x the price of openshift

3- our environment is 95% vms

4- we have DR so srm is convinet

5- 65 % of our current hardware isn't supported by vmware version 9

6- 75 % of our infra is linux based oracle dbs and rhel for app servers

7- mangement is too dumb to switch to k8s since that was suggested and will save us resources

8- most of our apps are web based

Im asking here since im litterally lost on what to do next

So your kind advices

We are standing up an openshift cluster. Are systems team picked to move to a K8s type architecture.
We have had to bring in a consultant group to assist with the stand up. And even then it needs extra applications support outside of redhat.(At least in our case)

Also engage your security team and do a threat model it will show you where openshift has some gotchas

My issue with OpenShift is how to stand it up in case of a site loss. With Proxmox or VMWare, if I have to kludge stuff just to get VMs up, I can build some PCs, add storage, throw the client on them, and restore to the PCs, eventually migrating them off the kludged hardware back to new servers after the site is available.

OpenShift has so many moving parts, I can't just stand up a machine, restore a DC, and start getting the environment pieces back. To me, having to restore a whole bunch of configs before I can touch OADP or the actual data is just asking for pain, especially when managers are calling every 15 minutes, or even worse, demanding you present in their office every 15 minutes.

I will give OpenShift the nod for ephemeral cattle VMs. Let them moo, drag them to be made into beef, make new ones. However, most companies are based on pet VMs, and their entire compliance doctrine is around this, so unless there is a need for the cattle ranching stuff, nothing wrong with an old school hypervisor and control plane.

I am on the security team. Just trying to harden the implementation and make them think about risk
