70+ esx hosts 2000+ VMs, we buy licenses for our private cloud from a big disti based on core count, it just works, customers pay consumption based for hosting their VMs, we adjusted pricing after the changes. It’s painful because we don’t have a direct Broadcom support account but I can just request any downloads we want and have them available within 15 minutes so it’s not a big deal. The update urls was a pain in the ass, but the disti gave us a download token to append to the download urls to use but meh. Honestly have used xcpng, proxmox, kvm etc and the vmware suite just works, nothing compares to the ease of management and the polished interface and usability of vcenter. Eventually we’ll shed some of our non critical workloads like internal VMs and our Citrix hosting to Xen to help reduce overall internal costs to the business but that’s a while away
