3-year cost calculator
Pre-filled for Rocky Linux → Ubuntu Server. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
How this is licensed: On virtual machines, RHEL/SUSE/Windows are effectively counted by vCPU (or per-VM subscription) rather than physical sockets; bare-metal socket/core rules differ. Windows Server Datacenter licenses physical cores of the host but allows unlimited VMs. Set $/vCPU to your subscription model.
All figures are illustrative and fully editable — adjust the cost-per-vCPU and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
