Key Components of AWS Organizations

1. Master Account (Management Account):
   • The first account created in AWS, also known as the Management Account.
   • Has full control over the organization and manages all other accounts.
   • Example: The Master Account controls permissions, billing, and overall management.
2. Organizational Units (OUs):
   • Groups of accounts organized by the company’s needs (e.g., by environment or team).
   • Example: Separate OUs for Development, Staging, and Production.
3. Accounts:
   • Individual AWS accounts within the organization.
   • Example: A Development Account and a Production Account.
4. Users:
   • People who access AWS resources, with different permissions.
   • Example: A developer has access to the Development Account but not the Production Account.
5. Policies:
   • Define what actions users or accounts can perform.
   • Example: A Security Account may only have read-only permissions.
6. Roles:
   • Temporary access to AWS resources with specific permissions.
   • Example: A role for a deployment team to access EC2 instances during a deployment.
7. Resources:
   • AWS services like EC2, S3, RDS, etc., that are created and managed within accounts.
   • Example: A Development Account may have a staging EC2 instance for testing.
8. Root User:
   • The original user created in an AWS account, with full access to everything.
   • Example: The Root User sets up the account and manages critical resources
