In this chapter, we covered three types of storage services in OpenStack: BLOB storage Swift, block storage Cinder, and image storage Glance. We discussed the two components of Glance, API and registry, and installation of the service. Followed by this, we discussed the three components of Cinder, API, scheduler, and volumes and installation of the service. Finally, we discussed the two components of Swift, Swift Proxy and rings. We also discussed the three types of rings: account, container, and object rings. In addition, we verified our installation and covered some basic troubleshooting just in case you face any issues during installation.

Now that we have seen how to build a storage base to store images and other stuff, in the next chapter, we shall look at building a cloud fabric controller using Nova, which is considered the pivot around which most of the OpenStack components function.
