The following patterns are described as 'architectural patterns' in POSA2. Despite the description, most of these do not fit the definition of an architectural pattern as described in POSA1.

 Interceptor - Add service transparently to a framework and triggered automatically when certain events occur
 Reactor - allows event-driven application to demultiplex and dispatch service requests from clients
 Proactor - similar to reactor but allowing for asynchronous operations
 Half-Sync/Half-Async decopules asynchronous and synchronous service processing
 Leaders/Followers provides and effcient concurrency model where multiple threads take turns
