For automating the deployment of a three-tier web application (Web, App, DB layers) on GCP using an IaC approach, which combination of services and tools would you recommend?

*Terraform, combined with Google Cloud Storage (GCS) for state management and GitHub for version control, is the ideal choice for automating the deployment of a three-tier web application on GCP using Infrastructure as Code (IaC. . Terraform enables the creation, modification, and versioning of infrastructure safely and efficiently. GCS serves as a backend for maintaining the state of Terraform configurations, ensuring consistency and traceability. GitHub integration offers a robust platform for version control, allowing for collaborative development and tracking of changes over time. This combination provides a comprehensive solution for deploying and managing complex multi-tier applications, ensuring efficient version control and state management. The other options lack either the comprehensive IaC capabilities of Terraform, the robust state management solution provided by GCS, or the version control and collaboration features of GitHub.*
