1. Developer
- Role: The developer creates both the Terraform configuration files and the application code, ensuring that infrastructure and application requirements align seamlessly.

2. Source Control
- Process: After writing the code, the developer commits changes to a local Git repository. This is followed by pushing these commits to a remote repository, allowing for collaborative development and version control.

3. Static Code Analysis
- Purpose: Before initiating the CI/CD pipeline, a static code analysis tool, such as SonarQube, scans the code for potential security vulnerabilities and assesses overall code quality. This step helps catch issues early in the development process.

4. CI/CD Tool Trigger
- Action: The push to the remote repository automatically triggers the CI/CD pipeline configured in Jenkins, initiating the automated workflow.

5. CI/CD Tools
- Options: Various CI/CD tools are available, including CircleCI, GitHub Actions, and ArgoCD, providing flexibility based on project needs and team preferences.

6. Terraform Initialization
- Command: Jenkins executes the `terraform init` command to set up the Terraform working directory. This step involves downloading the necessary provider plugins to ensure proper configuration.

7. Infrastructure Planning
- Execution: The `terraform plan` command is run by Jenkins, generating an execution plan that outlines the actions Terraform will take to achieve the desired state specified in the configuration files.

8. Infrastructure Application
- Implementation: Jenkins then runs `terraform apply`, applying the planned changes to the infrastructure. This step implements actual modifications to the cloud resources as defined in the Terraform configuration.

9. Infrastructure Deployment
- Outcome: The infrastructure is deployed to the designated cloud provider, such as AWS, Azure, or GCP, ensuring that resources are correctly provisioned.

10. Infrastructure Ready for Use
- Result: The deployed resources, including virtual machines, networks, and storage, are now provisioned and available for immediate use, enabling further development and deployment of applications.
