In the previous chapter, we discussed the Swift object storage service and all the Swift-related objectives in the COA exam. Now we will discuss Heat. Heat is the OpenStack orchestration service, and its goal is to help OpenStack users model, set up, and automate the creation and management of OpenStack resources. Due to to the minimal amount of Heat content in the exam, this chapter will be short and sweet. We will cover the following topics:
- About Heat
- Heat architecture
- Heat templates
- Exam objective - managing stacks
- Exam objective - updating stacks
After this chapter, you should have a solid understanding of Heat and the skills required to successfully fulfill all Heat-related objectives in the exam.
