Google Deployment Manager

1. Infrastructure as Code (IaC): Deployment Manager lets you define your cloud resources using declarative YAML or Python templates, making it easy to version and manage your infrastructure configurations.
2. Templates: Deployment Manager templates describe the resources you want to create, such as virtual machines, storage buckets, networks, and more.
3. Deployment: You create deployments using templates, specifying the resources you want to provision and their configurations.
4. Preview and Update: Before making changes, you can preview what the deployment will look like. You can also update existing deployments to apply changes.
5. Parameterization: Templates can be parameterized, allowing you to customize configurations based on different environments or requirements.
6. Reusable Templates: Deployment Manager supports importing and using reusable templates, promoting modular and scalable infrastructure designs.
7. Deployment History: You can view the history of deployments and their changes, enabling better tracking and management.
8. Rollback: If issues arise after an update, you can roll back to a previous deployment state.
