One of the most critical things I learned this week is the level of abstraction involved with configuring Aruba Mobility Controllers. In order to configure something as simple as a set of access points with multiple SSIDs (e.g., employee and guest), you actually create two different "Virtual APs" or VAPs. Then you associate those two VAPs with an "AP Group". Then you provision particular APs to that group. It's a little challenging to get used to after working with Cisco for so long, but it's a very powerful way of configuring the controller. The concept of object-oriented programming comes to mind.
