Nova-Compute service

As you may already know, Nova is the original core component of OpenStack. From an architectural level, it is considered one of the most complicated components of OpenStack. Nova provides the compute service in OpenStack and manages virtual machines in response to service requests made by OpenStack users.

What makes Nova complex is its interaction with a large number of other OpenStack services and internal components, which it must collaborate with to respond to user requests for running a VM.

Let's break down the Nova service itself and look at its architecture as a distributed application that needs orchestration between different components to carry out tasks.
