What does AWS Resource Access Manager (AWS RAM) enable?

AWS Resource Access Manager (AWS RAM) is designed specifically to enable the secure sharing of resources across different AWS accounts. This service allows organizations to efficiently share resources like Amazon VPC subnets, transit gateways, and other services with other accounts within the same organization or even with accounts outside the organization. By using AWS RAM, administrators can manage access to these shared resources without duplicating the resources themselves, leading to more streamlined operations and cost savings.

This capability is particularly beneficial for organizations that have multiple AWS accounts and need to collaborate or use shared services while maintaining fine-grained access controls. The security and access control mechanisms provided by AWS RAM help ensure that resource sharing is done in a controlled and secure manner, minimizing the risk of unauthorized access.

The other options focus on aspects like user monitoring, automation, and third-party integration, which are not the primary purpose of AWS RAM. Monitoring user access is typically managed through services like AWS CloudTrail. Similarly, resource automation can be accomplished with tools like AWS Systems Manager or AWS Lambda, while integration with third-party identity providers usually relates to identity management solutions rather than resource sharing specifically.
