OpenStack Nova

OpenStackComputeFree tier available

Compute service that schedules and manages virtual machine instances across hypervisors (KVM, libvirt, Hyper-V, VMware, Ironic for bare metal). The reference implementation behind every OpenStack-based private cloud — equivalent to EC2 / Azure VMs / Compute Engine in the cross-provider mapping
