Hi Al,
It's not different (but Sean's already said that). There are a couple of
things (at least) that make it more of a pain though, 1) you mightn't
own all the processes involved (a bit like not having source code in a
local app maybe) 2) the scale of a distributed system makes refactoring
your way out of trouble tough compared to a local app (locally, you can
often see what broke in front of your eyes).
