really ? Wow.. I've never had 120 VMs to manage in any org I was part of, and have worked on fortune 500 companies !
I have provided infrastructure-as-a-service for many many baremetal/VMS/containers, but then I wasn't managing them (e.g: it was many small team's infra, not a small team of 10 people using 20-120 VMs as per OP)
That didn’t come out well - by VMs I mean EKS or Swarm nodes not VMs in term of “pet” not “cattle” :-)
The number of nodes was used to run a monolith. Same deployments and all, wasn’t as complicated as it might sound (terraform to manage infra, few custom apps to talk to external APIs, etc)
These were definitely not 500 fortune companies but AFAIK all of them had some cash flow or were acquired by behemoths.
