Hi Daniel,
For a basic environment the AP-LIC (AP capacity licence) are required and the AP-PEF (Policy Enforcement Firewall) are strongly recommended. Both licences must be the same amount as your access points count.
Other licences could be add on your need, like the AP-RFP (RF-Protect) for
spectrum analysis and Wireless Intrusion Protection (WIPS) features. Or an Web-CC (WEB Content Classification) subsciption for content clasification filtering. All this licences are in the same amount of your access points.
An Aruba Mobility Master is strongly recommended and is required if you like an active/active cluster with hitless failover, in service upgrades, or features like Airmatch what is the smarter equivelant of the basic available ARM (Adaptive Radio Management). A Mobility Master can act as central configuration, licence server and management platform. An MM-VA-500 license is needed to run the Mobility Master (as virtual appliance on your own VMware or Hyper-V plaform). The amount of mobility master licences count as accesspoints+controllers, for example 498 accesspoints and 2 managed device controller.
Note that the Mobility Master have recently got a new name, the new name is a Mobility Conductor but means the same.
There are other options an strategies available for each use case, thats why we recommend to team with your local Aruba partner to create the best design for your environment.
Also take a look into the datasheets for some more information.
