Amazon Web Services Resource Access Manager
Simple, secure service to share Amazon Web Services resources
Amazon Resource Access Manager (RAM) is a service that enables you to easily and securely share Amazon Web Services resources with any Amazon Web Services account or within your Amazon Web Services Organization. You can share Amazon Transit Gateways, Subnets, Amazon License Manager configurations, and Amazon Route 53 Resolver rules resources with RAM.
Many organizations use multiple accounts to create administrative or billing isolation, and to limit the impact of errors. RAM eliminates the need to create duplicate resources in multiple accounts, reducing the operational overhead of managing those resources in every single account you own. You can create resources centrally in a multi-account environment, and use RAM to share those resources across accounts in three simple steps: create a Resource Share, specify resources, and specify accounts. RAM is available to you at no additional charge.
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.
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.
