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 code and to apply some of its key features and functionalities to create and manage Google Cloud infrastructure. This course demonstrates how to create and manage projects and resources on Google Cloud Platform with Terraform. With Terraform, many of your resources — such as projects, IAM policies, networks, and Compute Engine instances — can be managed, versioned, and easily recreated for your organization or teams. The state that Terraform generates is saved to Google Cloud Storage for persistence.

Learners will get hands-on practice building and managing Google Cloud resources using Terraform.

Course Objectives:

• 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.
• Provision Google cloud resources with Terraform script
• Get hands-on about HashiCorp configuration language
• Create infrastructure for compute, storage network and Database product in GCP
• Create infrastructure by writing code in HCL
• Deploy Storage & database infrastructure using Terraform
• Create VM, HostApp with RUN, & Deploy services as function
• Provision networking resources VPC, Subnet & Firewall with HCL
