intersubsystem
Intersubsystem refers to the coordinated exchange of information and control signals between distinct subsystems within a larger system, such as a software platform, an operating system, or a distributed application. It encompasses the mechanisms, protocols, and governance required for subsystems to interact without assuming full knowledge of each other’s internal implementations. The term covers both software components and hardware or organizational units that must cooperate to achieve a common function.
The scope of intersubsystem interaction includes request–response communications, event or message passing, and shared resources. It
Common mechanisms and protocols used to realize intersubsystem communication include message queues, inter-process communication, event buses,
Challenges in intersubsystem design involve managing coupling, dealing with partial failures, maintaining data consistency, handling schema
