Currently, I am have a VMware vCenter 7 4 node cluster. These are the Lenovo m920q machines with 64GB RAM each. I also have a Synology 4 Disk NAS too.
I deploy standard VMs and Rancher k8s clusters and use full automation (mainly Terraform) to build everything.
Why VMware? Mainly to get experience on it.
Why am I interested in OpenStack? Mainly because I have used it before and really enjoyed that experience as it feels more like a true cloud environment.
So, my question is this.... Has anyone switched one way or the other? Were you glad at switching or do you regret it?
If you did switch, what is a good way to setup multi node OpenStack? I see people recommend at least one separate controller vs the compute nodes?
Don't "need" to, no. I can put it on top, so that is what I planned to do to POC, but if I like it, I would rather not have software/resources taken up on top of resources. But I am asking if anyone has already done this either direction and their experience.
