# Resource Access Manager (RAM)

**Introduction**

* Share AWS resources (ex. VPC) that you own with other AWS accounts.
* Share with any account or within your Organization
* Avoid resource duplication.

**Feature**

* Integrate with AWS Organizations
  * Enable trusted access: From the AWS RAM CLI, use the `enable-sharing-with-aws-organizations` command.
* VPC Subnets
  * Allow to have resources launched in the same subnets.
  * Must be from the same AWS Organizations.
  * Cannot share security groups and default VPC.
  * Participants can manage their own resources in there.
  * Participants can't view, modify, delete resources that belong to other participants or the owner.
* AWS Transit Gateway (a network transit hub to interconnect your VPC and on-premises networks)
* Route53 Resolver Rules
* License Manager Configurations
