Deploying OpenStack

Chapter 6. Planning Nova Deployment

As Nova supports a wide range of technologies, configurations, and designs, it will be important to make a number of architectural and design decisions before looking to deploy it. This section guides you through the most important ones before you begin.

Deployment of Nova can be painless with good planning. However, Nova does have a lot of moving parts, so it’s good to understand an overview of what is trying to be accomplished before you start installing software. Figure 6-1 illustrates the preferred workflow for installing, configuring, and launching your first instance on Nova.

This is a three-step process:

• Planning Nova Deployment to decide on deployment scenario, finalize key design choices, and ensure hardware meets requirements

• Installing Nova to get the software, prerequisites, and configurations onto the servers

• Using Nova to prep the system for your initial users

Note

This book covers the infrastructure for clouds. As such, it is out of scope of the book to describe everything that you will want to do with your cloud instance once you have it running.

At each phase of the installation, we will make sure to test the results of our actions. Without these tests, it is very easy to get to the last steps and find out you need to start over again due to error in an early phase.
