What Does Decoupled Architecture Mean?
Decoupled architecture is a type of computing architecture that enables computing components or layers to execute independently while still interfacing with each other. Decoupled architecture separates a system’s memory access and instruction cycle processes from execution-stage processes by implementing a data buffer.
Techopedia Explains Decoupled Architecture
Decoupled architecture is primarily implemented to achieve higher computing performance by isolating and executing individual components independently and in parallel. It is generally applicable to instruction-based processes between the memory and a pipelined processor where multiple instructions are queued in series. Both the data fetching and execution stage processes use the data buffer and processor's pipelining ability to execute both stages' processes in parallel. The performance of these operations largely depends on the size of the buffer; a large buffer can store data for many processes.
Decoupled architecture is also used in software development to develop, execute, test and debug application modules independently. Cloud computing architecture is also referred to as an implementation of decoupled architecture where the vendor and consumer independently operate and manage their resources.
