In general, a decoupled architecture is a framework for complex work that allows components to remain completely autonomous and unaware of each other. Cloud computing is sometimes said to have a decoupled architecture because the cloud provider manages the physical infrastructure , but not the applications or data hosted on it.

In computing,the term decoupled architecture describes a processor in a computer program that uses a buffer to separate the fetch the decode stages from the execution stage. A decoupled architecture allows each component to perform its tasks independently of the others , while also enabling structural variations between source and target.
