Which is the most suitable architecture design for an application that must be versioned and managed as much as possible?

The most suitable architecture design for an application that must be versioned and managed extensively involves storing both application and infrastructure code in Git and utilizing a deployment tool like Terraform. This approach promotes a clear separation of concerns and allows for rigorous version control and collaboration among team members.

By keeping the application's source code and the configuration for infrastructure in a Git repository, you enable a comprehensive history of changes, which is crucial for rollback and audit purposes. Every change made can be tracked, and collaboration practices, such as pull requests and code reviews, can be implemented, enhancing code quality and stability.

Using Terraform to manage infrastructure as code (IaC) aligns perfectly with this versioning need. Terraform allows you to define your infrastructure in a declarative manner and version it alongside your application code. This means that any changes to the infrastructure can also be tracked and managed in the same version control system, simplifying deployments and reducing the risk of configuration drift.

By integrating these practices, teams can efficiently manage complex application dependencies, automate the deployment process, and ensure consistency across different environments, contributing significantly to the overall reliability and maintainability of the application.

Deploying Jenkins from Google Cloud Marketplace is more focused on continuous integration and delivery processes but does not inherently support the extensive versioning and
