When this person looks down the line-of-sight from the datacenter to the users he/she is supporting, it looks something like this. Presentation Server is the application delivery controller that initiates the delivery process for Windows applications at the point-of-origin, so this product is the center of gravity for this individual. Products like Access Gateway, WANScaler and EdgeSight are common to all applications, so they are also essential to IT infrastructure ops.
