The primary means by which architectural styles induce simplicity is by applying the
principle of separation of concerns to the allocation of functionality within
components. If functionality can be allocated such that the individual components are
substantially less complex, then they will be easier to understand and implement.
Likewise, such separation eases the task of reasoning about the overall architecture. I
have chosen to lump the qualities of complexity, understandability, and verifiability
under the general property of simplicity, since they go hand-in-hand for a network
based system.
