Creating an Application

If the resource structure is complex, for example, an application has multiple components, and each component involves resources in multiple regions, you can use the advanced creation method.

1. On the application creation page, click the Advanced Creation tab.
2. Select an application structure type based on the complexity of the application structure.
   • Lightweight: Lightweight applications feature fewer layers and a simpler structure. Application layer structure: Applications > Components > Groups > Resources
   • Large-scale: Large-scale applications have complex structures. Application layer structure: Applications > Sub-applications (multi-layer) > Components > Groups > Resources.

3. Set the application structure by referring to Table 1.
   

   After setting all mandatory fields of the current level, click OK to go to the next level. After all mandatory fields of all levels are specified, click OK to complete application creation.

   Table 1 Parameters for creating an application

   Available Cloud Service Providers	Select the cloud service provider to which the target instance belongs.	Huawei Cloud
   Resource Association Method	Select a resource association mode. Manual association: You can manually associate resources with the group you created for unified management. Automatic association: You can add all resources with the same tag in an enterprise project to a resource group.	Manual association
   Region	Select a region from the drop-down list.	-
   Enterprise Project	This parameter is required only when Resource Association Method is set to Automatic association. Select an enterprise project from the drop-down list.	-
   Tag Key	This parameter is required only when Resource Association Method is set to Automatic association. Enter the tag key of the target instance.	testKey

   Associate Resource with APM Environment	(Optional) Configure the application, component, and environment of the APM service corresponding to the group. APM service performance information can be obtained through this field during fault diagnosis.	-

4. Click Create to complete application creation.

If the resource structure is simple, for example, an application requires only Huawei Cloud resources and the resources need to be associated with only one group, you can use the quick creation function.

1. On the application creation page, click the Quick Creation tab.
2. Set basic application information.
