Application Services requires that vCloud Director use specific configuration settings. For previously installed configurations of vCenter Server and vCloud Director servers, verify that these servers use the settings that work with Application Services.

The virtual appliance on which you run Application Services must meet certain hardware and software requirements. In addition, you must open certain ports for Application Services.

You must set up the storage and network of your vCenter Server cluster configurations to meet certain requirements so that you can install Application Services in vCloud Director or vSphere.

You must configure a virtual appliance in vCloud Director to successfully install Application Services. If you have a previously installed version of vCloud Director, you must check the configuration settings to optimize for Application Services.
