Summary

This chapter has explored the most trending OpenStack storage services. The expansion of each storage service feature and capability, including Swift, Cinder, and Manila, is almost unstoppable. This is confirmed by the vast array of supported backend drivers, either with the open source world ones, such as Ceph, or with a specific storage vendor. The latest OpenStack releases, including Antelope and Bobcat, have also introduced more stable advanced features, mainly for Cinder and Manila, through the scheduling and filtering mechanisms. Bear in mind that understanding each storage use case and its respective architecture are the keys to comfortably running a storage solution in an OpenStack environment, based on your requirements. The challenge of picking the right option to satisfy specific requirements is not limited to storage topics. It also applies to the networking paradigm in OpenStack. Connecting the different elements of the compute and storage services will be discussed...
