With our switch from Citrix CSP Standard to Citrix CSP UHMC licenses, I prepare to provide WEM to different customers. In the past, I always deployed two All-In-One Controllers for our small customers: Delivery Controller, Storefront, Director and WEM Broker. Load Balanced with NetScaler. Now I read, that Citrix documents, that you should not install the WEM Broker onto the Delivery Controller. (Source: https://docs.citrix.com/en-us/workspace-environment-management/current-release/quick-start-guide.html#installation-and-configuration) For an environment with 50-200 CCU, that already has two VMs for Controller/Storefront, why do I need additional VMs for WEM Broker?

This is mainly for the stability of the system. Broker/controller/storefront are key components, it is recommended to use a separate VM to run installation.

Okay so no known conflicts? Just my own risk? Because I tend to disagree. More VMs means also more potential sources of failure.
