Simply and securely share your AWS resources across multiple accounts
Simplify your security and access controls across shared resources.
Streamline management of AWS resources within your organization from a central account.

How it works
AWS RAM helps you securely share your resources across AWS accounts, within your organization or organizational units (OUs), and with IAM roles and users for supported resource types.

Use cases
Share resources in multi-account environments
Share foundational infrastructure like Amazon VPC subnets across accounts, allowing multiple accounts to deploy application resources to the same subnet
Centrally govern access to resources
Centrally manage resources like private certificate authorities allowing certificate issuance across multiple accounts to manage cost and reduce operational overhead
