is a service that helps you manage multiple AWS accounts from one central place. Instead of juggling lots of accounts separately, you can organize them, apply rules, and control access all in one go.

Why it exists

• To simplify billing: Consolidate bills from all accounts into one invoice. 💸
• To control access and permissions: Set rules for what accounts or users can do.
• To improve security: Separate accounts by team, project, or environment (like dev, test, and prod).
• To scale efficiently: Manage many accounts without chaos.

Key Components

• Dev Account : where you freely build and break things while writing code 🧪
• Staging and Testing Account : where you safely check if everything works as expected before release 🔍
• Production Account: where real users use the app, so changes are rare, careful, and controlled 🚀

One-line memory hook: Build in Dev, verify in Test, serve users in Prod.

Dev team works mainly in Account A

QA team works mainly in Account B

Ops / Senior engineers work in Account C
