Accessing Terraform Remote State Data in GCP

You are a DevOps engineer working at an organization that is trying to move all its configuration management to Infrastructure as Code (IaC). There is some concern about this plan, since many teams work independently. You will meet with the networking team to set up an initial VPC using Terraform with a remote state backend that other teams can access. Next, you will meet with one of the application teams to configure Terraform to deploy their VMs into the VPC that the networking team has created and will manage. Once this is set up, the networking team can manage the VPC as they need to and the latest information will be available for the application teams via the Terraform remote state backend.
