Summary
In this chapter, you gained an understanding of Terraform's core components, including providers, resources, variables, output, and data sources. In a nutshell, a provider is an API plugin that you need if you want to deploy/update services for your infrastructure. Resources are the actual services that you are planning to update/deploy for your respective providers. Variables are input from the users that makes your configuration code reusable. The output is what you are expecting when you are creating/updating your resources. Data sources help you out with extracting existing resource configurations. All of these help you to draft your Terraform configuration file.
In the next chapter, we will get into a detailed discussion regarding backend configuration, provisioners, and inbuilt functions, how to perform debugging in Terraform, and how you can perform different kinds of iteration using for and other loops in Terraform.
