Amazon Resource Access Manager

Simple, secure service to share Amazon Web Services resources

Amazon Resource Access Manager (RAM) helps you securely share your resources across Amazon Web Services accounts, within your organization or organizational units (OUs) in Amazon Web Services Organizations, and with IAM roles and IAM users for supported resource types. You can use Amazon RAM to share transit gateways, subnets, Amazon License Manager license configurations, Amazon Route 53 Resolver rules, and more resource types.

Many organizations use multiple accounts to create administrative or billing isolation, and to limit the impact of errors. With Amazon RAM, you don’t need to create duplicate resources in multiple Amazon Web Services accounts. This reduces the operational overhead of managing resources in every account that you own. Instead, in your multi-account environment, you can create a resource once, and use Amazon RAM to share that resource across accounts by creating a resource share. When you create a resource share, you select the resources to share, choose an Amazon RAM managed permission per resource type, and specify whom you want to have access to the resources. Amazon RAM is available to you at no additional charge.

Benefits

Reduce Operational Overhead

Procure Amazon Web Services resources centrally, and use RAM to share resources such as subnets or License Manager configurations with other accounts. This eliminates the need to provision duplicate resources in every account in a multi-account environment, reducing the operational overhead of managing those resources in every account.

Improve Security and Visibility

RAM leverages existing policies and permissions set in Amazon Identity and Access Management (IAM) to govern the consumption of shared resources. RAM also provides comprehensive visibility into shared resources to set alarms and visualize logs through integration with Amazon CloudWatch and Amazon CloudTrail.

Optimize Costs

Sharing resources such as Amazon License Manager configurations across accounts allows you to leverage licenses in multiple parts of your company to increase utilization and optimize costs.
