In the previous chapter, we started with OpenStack with Ubuntu and we saw the architecture, environment, and various components of the OpenStack setup. We talked about services such as Identity service, Image service, Compute service, Dashboard, Networking, Block Storage, and Object Storage. In this chapter, we will cover the remaining components, namely, Orchestration, Telemetry, Database, and Data Processing services. Also, we will look at some of the best practices for the Ubuntu OS.
