Terraform Cloud and Terraform Enterprise are powerful tools that extend the capabilities of Terraform by providing collaboration, governance, and automation features. These tools are designed to help teams manage infrastructure as code (IaC) more effectively and securely.

• Terraform Cloud: A SaaS offering by HashiCorp that provides a collaborative environment for teams to manage Terraform configurations.
• Terraform Enterprise: A self-hosted version of Terraform Cloud with additional features for large organizations, including advanced security and compliance controls.

• Workspaces: Isolate different environments (e.g., development, staging, production) within the same project.
• Version Control Integration: Automatically trigger Terraform runs based on changes in your version control system (e.g., GitHub, GitLab).
• Policy as Code: Use Sentinel to enforce policies and ensure compliance with organizational standards.

• Remote Operations: Execute Terraform runs in a remote environment, reducing the need for local execution and improving security.
• Run Triggers: Automatically trigger Terraform runs based on changes in other workspaces or external events.
• Notifications: Integrate with Slack, email, and other tools to receive notifications about Terraform runs.

• State Management: Securely store and manage Terraform state files in a remote backend.
• Role-Based Access Control (RBAC): Define fine-grained access controls to manage who can perform specific actions.
• Audit Logging: Track changes and access to Terraform configurations and state files for compliance and troubleshooting.

3. Monitor the run progress and review the plan and apply steps.

1. In your Terraform Cloud workspace, go to the "Version Control" settings.
2. Select "GitHub" and authorize Terraform Cloud to access your GitHub account.
3. Choose the repository that contains your Terraform configuration.

1. Create a .github/workflows/terraform.yml file in your repository with the following content:

   name: 'Terraform'
   on:
     push:
       branches:
         - main
   jobs:
     terraform:
       runs-on: ubuntu-latest
       steps:
         - name: Checkout code
           uses: actions/checkout@v2
         - name: Setup Terraform
           uses: hashicorp/setup-terraform@v1
           with:
             terraform_version: 1.0.0
         - name: Terraform Init
           run: terraform init
         - name: Terraform Plan
           run: terraform plan
         - name: Terraform Apply
           if: github.ref == 'refs/heads/main'
           run: terraform apply -auto-approve
   

2. Commit and push the changes to your repository.

1. Navigate to the "Actions" tab in your GitHub repository to monitor the progress of your Terraform runs.
2. Review the output of each step to ensure successful execution.
