## What it is
OpenStack Nova is the compute service of OpenStack, acting as a cloud computing fabric controller that provisions and manages virtual machines, containers, and bare metal across hypervisors like KVM, Xen, VMware, and Ironic. It exposes a REST API for instance lifecycle management and is a core component of private and public OpenStack clouds.

## Use cases
- run a private cloud with vm provisioning
- manage compute instances across multiple hypervisors
- schedule and launch vms via a rest api
- provision bare metal nodes with ironic
- build an iaas platform on open source
- automate instance lifecycle in an openstack cloud

## When to choose
- you are deploying or operating an OpenStack cloud and need compute management
- you need multi-hypervisor vm and bare-metal provisioning at scale
- you want an open-source alternative to public cloud compute with a standard REST API

## When to avoid
- you only need container orchestration rather than vm/bare-metal compute (use Kubernetes)
- you want a lightweight single-node virtualization manager
- you cannot operate the broader OpenStack ecosystem Nova depends on
