Multi-Environment (Dev / Staging / Prod) Setup

Summary

Show you can manage the same infrastructure pattern safely across multiple environments with different configurations — a realistic reflection of how most real companies actually organize infrastructure.

• 1Use Terraform workspaces or separate state files to manage 2-3 distinct environments.
• 2Show how configuration (e.g. instance size, replica count) differs sensibly between environments.
• 3Document your promotion process: how a change moves from dev through to prod.
