This course provides an introduction to using Terraform for Google Cloud. It enables learners to describe how Terraform can be used to implement infrastructure as a code and to apply some of its key features and functionalities to create and manage Google Cloud infrastructure. Learners will get hands-on practice building Google Cloud resources using Terraform.

What you'll learn

• Define the business need for infrastructure as code and the benefits of using it in your environment.
• Explain the features and functionalities of Terraform.
• Use Terraform resources, variables, and output values to create Google Cloud infrastructure resources.
• Use Terraform modules to build reusable configurations.
• Explain Terraform state and its importance.
