It's worth noting that even if all you have is a bunch of SOs floating around in the same "monolith" you still have a "distributed system" of a kind. You (probably) will never have to worry about partitions, but your state space is still going to be the multiple of all of your independent stateful threads. Obviously the solution would be to ensure that most SOs don't actually maintain much internal state to the greatest degree they can. This can be partially solved by abstracting out certain stateful primitives into other service objects—achieve this with dependency injection, perhaps.
