So far, we have learned about the various components of OpenStack such as Keystone, Nova, Swift, Cinder, Glance, and Neutron. In this chapter, we have looked at Horizon, which is fundamentally the web interface to all these components.

In the next chapter, we will see how all the components we have installed and configured so far will work together to provide a cloud-based Infrastructure as a Service. This is where we will see Horizon put to use, to configure services, request virtual machines, storage, and so on.
