What is AWS Organizations?

AWS Organizations is an account management service that enables you to consolidate multiple AWS accounts into an organization that you create and centrally manage. It helps you centrally manage billing, control access, compliance, and security, and share resources across AWS accounts. Organizations provides Service Control Policies (SCPs) to set permissions guardrails on accounts. It enables automated account creation, hierarchical grouping of accounts using Organizational Units (OUs), and consolidated billing. Organizations helps enforce security best practices and implement governance across your entire AWS environment at scale.
