You can use application server clusters for coordinated multiserver management, which is not possible with standalone application server instances. The management and maintenance of changes to the configuration and deployment of the MDM Hub on an application server cluster is simpler than on multiple standalone application server instances.

Consider the frequency of the maintenance tasks, which impacts your decision in favor of a highly maintainable environment. During an MDM Hub installation or upgrade on standalone application server instances, you need to install or upgrade and deploy on each application server instance. Also, there are multiple configurations that need to be updated on each machine. On application server clusters, the installation or upgrade and deployment is relatively less tedious.
