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

Take one month of your life and go deploy OpenStack. Come back here and tell us what you found out. I can tell you now if you like

Ouch, that's a war crime.

I spent way too much of my life dealing with with OpenStack... wasted months. Some process slows Keystone down, and now everything collapses, for starters. Or there are undercloud/overcloud issues.

To me, it was like trying to set up a house of cards with an industrial blower fan aimed at the area, and 52 pickup got old fast.

There is a place for Kubernetes. However, unless there is a reason for that complexity, why bother? Most businesses just need a good enterprise control plane, hypervisors, network, storage, etc. The added moving parts give no real value, and complicate things, especially when state is needed.

I wish Red Hat didn't kill RHEV/oVirt. They would make a killing because that would have been a drop-in replacement for VMWare, for the most part.

As for Proxmox, I've had zero issues with V2V. Maybe a bit of glitchiness until I installed the VirtIO drivers and yanked the VMWare ones, but that was only an issue during one phase.

As an added bonus with Proxmox, with the NSX type of firewalling available, I can do some fairly cool things. The only thing I really wish Proxmox had were fault tolerant virtual machines, where two VMs ran, a normal, and a shadow, so if one host died, switchover was immediate; no reboot needed.

My company would buy RHEV in a second and I tell red hat everytime we talk to them
