The full-featured virtualization platforms VMWare or Proxmox allow you to create your own virtual servers (VPS) online via a web interface and change their parameters ( CPU, RAM, HDD/SSD, NIC ). In addition, the virtual datacenter offers the possibility to access control via API for convenient process automation. Reserved capacity for rapid performance increases on a fully redundant hardware base. The possibility of deploying Kubernetes/Docker technology is a matter of course.
A simpler path to virtualization is a basic Virtual Server (VPS).
