Shameless link alert! ALERRTTTT!
This is a really, really good reference architecture paper – I think most of us within the space can setup and configure components such as workspace/Identity manager and Appvolumes, but not everyone gets the opportunity to really go to town across multiple sites with a view to building it up from the bottom – so this is where this paper comes in really handy. There’s everything you need for those situations where you’d have go hunting for the further information and also helps for getting buy in as to what exactly is needed as defined by a whitepaper. There are other configurations as solutions for multi site architecture (I know, I’ve done a few myself), but with this, you know exactly what you put in and what you’ll get out.
