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

Flavours
Hardware profile templates (vCPU, RAM, disk) — the OpenStack equivalent of EC2 instance types. The `nova-flavors` id keeps the US spelling because that's the actual OpenStack API path (/v2.1/{tenant_id}/flavors/); only the user-visible display name is anglicised.
Server Groups
Affinity / anti-affinity scheduling so workloads land on the right hypervisors for HA
Cells v2
Horizontal scaling primitive for very large deployments — partitions compute hosts into independently-scheduled cells
