What Is AWS RAM?

AWS Resource Access Manager (AWS RAM) enables you to share your resources with any AWS account or through AWS Organizations. If you have multiple AWS accounts, you can create resources centrally and use AWS RAM to share those resources with other accounts.


AWS RAM offers the following benefits:

  • Reduces operational overhead—Create resources centrally and use AWS RAM to share those resources with other accounts. This eliminates the need to provision duplicate resources in every account, which reduces operational overhead.

  • Provides security and consistency—Govern consumption of shared resources using existing policies and permissions, to achieve security and control. AWS RAM offers a consistent experience for sharing different types of AWS resources.

  • Provides visibility and auditability—View usage details for shared resources through integration with Amazon CloudWatch and AWS CloudTrail. AWS RAM provides comprehensive visibility into shared resources and accounts.

How Resource Sharing Works

When you share a resource with another account, then that account is granted access to the resource. Any policies and permissions in that account apply to the shared resource.

Sharing Your Resources

You can share resources that you own by creating a resource share. When you create a resource share, you specify a name, the resources to share, and the principals with whom to share. Principals can be AWS accounts, organizational units, or an entire organization from AWS Organizations. Your account retains full ownership of the resources that you share.

Using Shared Resources

When the owner of a resource shares it with your account, you can access the shared resource just as you would if it was owned by your account. You can access the resource using the respective service's console, AWS CLI, and API. The actions that users are allowed to perform vary depending on the resource type. All IAM policies and service control policies configured in your account apply, which enables you to leverage your existing investments in security and governance controls.
