The application group feature allows you to manage resources from different services and regions by group. You can create application groups based on your business requirements. You can add servers, databases, or other resources that are related to the same business to an application group. You can also manage alert rules by application group.
Background information
The following table describes the methods that you can use to create application groups and the Alibaba Cloud services that are supported by each method.
Creation method | Description | Supported Alibaba Cloud service |
Create an application group based on tags | If tags are attached to your instances, you can specify a tag-based matching rule to create an application group. All instances that match the rule are automatically added to the application group. If an existing instance has a tag that is specified in the matching rule, an application group is automatically created for the tag. If a new instance has a tag that is specified in the matching rule, the instance is automatically added to the application group. Up to 3,000 instances can match a rule at a time. For more information about how to create and attach tags in the Resource Management console, see Add a custom tag. |
