Resource Access Management (RAM) is an identity management and access control service that is provided by Alibaba Cloud. RAM allows you to create and manage RAM users for identities such as employees, systems, and applications. You can manage permissions of RAM users to control their access to Alibaba Cloud resources.
If multiple users in your enterprise need to access the same resources, you can create RAM users and grant them minimum permissions. This eliminates the need to share the AccessKey pair of your Alibaba Cloud account with these users and reduces security risks.
