Summary

The list of components that have been covered is not the full list. This is just a small subset to get you started with using and understanding OpenStack. Now that we have introduced the OpenStack components, we will illustrate how they work together as a running OpenStack installation. To illustrate an OpenStack installation, we first need to install one. In the next chapter, we will use the RDO OpenStack distribution with its included installer to get OpenStack installed so that we can begin to investigate these components in more detail.
