In this chapter, we were introduced to Nova, the key service of OpenStack that provisions and manages compute resources, which is also called the Cloud Fabric Controller. We then looked at the various components of Nova such as Nova scheduler, Nova compute, Nova API, Nova volume, Nova conductor, and Nova console, and their interactions among themselves using a messaging queue. Finally, we looked at the installation and configuration of these components on the compute node and the controller node.

After storage and compute services, the next step is to set up a networking service. We will set up Neutron for networking in the next chapter and take it forward.
