In the first installment of the "Grid Watch" column, I gave you a brief overview of the Global Grid Forum (GGF). Now I'll turn my attention to grid architecture, a topic I find extremely hard to talk about. It's not that I think architecture is boring or unnecessary. Quite the contrary. It's just a huge, rambling, complex topic, and my job here is to pick out what's important to the developer community without getting too lost in the weeds.
