As enterprises grow, they need to provision and maintain an increasingly complex network of resources. Inevitably, more staff are needed to help manage these resources along with an ever-increasing number of accounts. To ensure operational efficiency while maintaining strict access control, it is essential to establish an organizational chart containing multiple hierarchies for resource management. Alibaba Cloud Resource Directory enables you to create folders for organizing accounts into hierarchies. You can create Resource Access Management (RAM) users and roles under different accounts to control access to resources. You can also create resource groups to organize resources into different groups based on their purpose.
