# Amazon Resource Access Manager Documentation

Amazon Resource Access Manager (Amazon RAM) helps you securely share your resources across Amazon Web Services accounts and within your organization or organizational units (OUs) in Amazon Organizations. For supported resource types, you can also share resources with Amazon Identity and Access Management (IAM) roles and IAM users. To reduce operational overhead in a multi-account environment, you can create a resource once and use Amazon RAM to share that resource across accounts.
