 ## Clustering
 
-App Service supports clustering for JBoss EAP versions 7.4.1 and greater. To enable clustering, your web app must be [integrated with a virtual network](overview-vnet-integration.md). When the web app is integrated with a virtual network, it restarts, and the JBoss EAP installation automatically starts up with a clustered configuration. The JBoss EAP instances communicate over the subnet specified in the virtual network integration, using the ports shown in the `WEBSITES_PRIVATE_PORTS` environment variable at runtime. You can disable clustering by creating an app setting named `WEBSITE_DISABLE_CLUSTERING` with any value.
