AWS Resource Access Manager (AWS RAM)

AWS service for securely sharing resources such as subnets, Transit Gateways and Route 53 Resolver rules across accounts.

Definition

RAM lets an account share supported resources with specific accounts, OUs or the whole organization without duplicating them. VPC subnet sharing lets multiple accounts launch resources into centrally managed subnets.

Example

A network account shares a Transit Gateway with all accounts in the Workloads OU through RAM.

Exam tip

RAM is the answer for sharing network resources centrally across accounts; it is not used for IAM permissions.
