Implementing GCP VPC Service controls using Terraform (Terragrunt)

VPC Service Controls is a powerful security feature offered by Google Cloud Platform that allows you to create a service perimeter to control communication within and across Google-managed resources. By defining ingress and egress rules, you can regulate access to resources and protect against unauthorized actions. Implementing VPC Service Controls involves configuring YAML files, setting up infrastructure using Terraform and Terragrunt, and adjusting access levels and permissions.
