In this section, we will look at one of the most useful management tools—Google Cloud Deployment Manager. It's important to understand the concepts of Cloud Deployment Manager for exam success.

Deployment Manager allows us to automate the creation and configuration of a variety of GCP resources. We can write all the resources our application needs in a declarative format using YAML files, which ensure repeatable deployments with consistent results. YAML is a data sequencing language that humans can easily read. Overall, Deployment Manager can be referred to as Infrastructure as Code (IaC). You may have some experience with tools such as Ansible or Terraform, and will recognize that the nesting of elements occurs through indentation, rather than any braces or brackets, which are used in some other languages.
