AWS Organizations is a service that allows you to manage multiple AWS accounts centrally. It helps you manage billing, control access, and automate workflows across multiple accounts, all while ensuring you maintain a secure and well-organized environment. AWS Organizations enables you to set up and manage accounts into a hierarchical structure, enforce policies, and simplify billing.
Account Management: Organize accounts into a hierarchical structure with organizational units (OUs).
Service Control Policies (SCPs): Set permission guardrails to restrict access to AWS services and resources across your organization.
Consolidated Billing: Combine multiple AWS accounts to receive a single bill, while still maintaining separate accounts for financial and operational purposes.
Resource Sharing: Share resources across multiple accounts.
Cross-account Access: Easily configure access for users or roles to multiple accounts.
Automated Account Creation: Automate the process of creating and managing AWS accounts within your organization.
Root User Access: To create or manage an AWS Organization, you must be signed in with an AWS root user or an IAM user with appropriate permissions.
AWS Organizations Service: Ensure AWS Organizations is supported and available in your region.
