To effectively administer compute, you must understand how the different installed nodes interact with each other. Compute can be installed in many different ways using multiple servers, but generally multiple compute nodes control the virtual servers and a cloud controller node contains the remaining Compute services.
The Compute cloud works using a series of daemon processes named
that exist persistently on the host machine. These binaries can all run
on the same machine or be spread out on multiple boxes in a large
deployment. The responsibilities of services and drivers are:

Some services have drivers that change how the service implements
its core functionality. For example, the

nova-scheduler also have drivers.
