Configuring Resource Groups for a Scalable Application

In a scalable application, an application runs on several nodes to create a single, logical service. If a node that is running a scalable application fails, failover does not occur. The application continues to run on the other nodes.

When a scalable application is managed as a resource in an application resource group, it is not necessary to colocate the application resource group with the device group. Therefore, it is not necessary to create an HAStoragePlus resource for the application resource group.

A resource group for a scalable application must have the following characteristics:

The following figure illustrates the configuration of resource groups in a scalable application.
