Application Management
Introduction
MAS uses applications to isolate resources of different users in the same instance. Resources (such as MySQL and Redis monitors) created in an instance must be associated with an application. By default, IAM users can only check and manage their own applications and resources. You can use your account to check and manage all applications and resources created by IAM users under your account.
Creating an Application
