AWS Resource Access Manager

AWS Resource Access Manager shares supported resources that one account owns with other AWS accounts, an organization, organizational units, and—in supported cases—specific IAM roles or users without cloning or moving the resources.

Why implement AWS Resource Access Manager?

  • Reduces duplicate infrastructure by letting multiple accounts use centrally owned supported resources such as subnets, transit gateways, resolver rules, and other listed types.
  • Can target an entire organization or OU so new member accounts receive intended access without enumerating every account.
  • Supports AWS-managed or customer-managed resource permissions and provides a central inventory of resources shared by and with an account.

How to implement AWS Resource Access Manager

  1. Confirm the resource type is shareable, its Region and service-specific constraints, owner and payer, quotas, blast radius, consumer responsibilities, and offboarding behavior.
  2. Enable organization sharing when appropriate, create a resource share with the smallest principal scope and managed permission, keep external principals disabled unless explicitly required, and handle invitations before expiry.
  3. In each consumer account grant identity-based access no broader than the share permission, test actual service operations, monitor CloudTrail and share state, and remove consumers before deleting or repurposing resources.

AWS Resource Access Manager best practices

  • Prefer organization or OU sharing for governed internal access, explicitly review the effect of OU changes and accounts leaving the organization, and avoid broad external-principal shares.
  • Remember that RAM is Regional and does not move or copy a resource; ownership, quotas, billing, and many controls stay with the producing account and vary by resource type.
  • Use least-privilege managed permissions plus consumer IAM policies, tag and inventory shares, monitor invitations and associations, and rehearse revocation without stranding workloads.

AWS Resource Access Manager use cases and server impact

  • Shared VPC subnets and transit infrastructure
  • Central DNS and network resources
  • Cross-account access to supported data, backup, or platform resources

Replaces duplicate per-account resources and custom resource-policy orchestration for supported types, while owner operations, consumer IAM, quotas, chargeback, lifecycle, and dependency management remain customer work.
