Summary

In this chapter, we learned about OpenStack, the open source cloud platform that offers IaaS features. OpenStack is made of several components, including Horizon (dashboard service), Nova (compute service), Neutron (networking service), Cinder (block storage service), Swift (object storage service), Glance (shared image service), Keystone (identify service), Ceilometer (telemetering service), Heat (Orchestration service), and Trove (database as a service). We also learned that Heat is the Orchestration service for OpenStack. We learned about the Heat authorization models, including password authorization, keystone trust authorization, and how these models work.
