CST(20)-Client/Server Hybrids:

Another point under consideration is that the industry is moving beyond the pure client/server model. This is because more intelligence is moving towards the client. Database clients keep snapshot of tables locally. TP monitor clients coordinate multiserver transactions. Groupware clients maintain queues. Multimedia clients check-in and check-out folders. Distributed object clients accept requests from objects anywhere. These new age clients must provide a server lite function – an interim step toward fulfilling the post scarcity vision of a full client and server function on every machine.

A server lite provides a thread, queue or background process on client machine that can accept unsolicited network requests from a server. For example, a server may call its clients to synchronize locks on a long duration transaction , refresh a database snapshot. Clients that provide server lite function are called hybrids as opposed to pure.
