Asynchronous queuing pattern

How can a service and its consumers accommodate isolated failures and avoid unnecessarily locking resources?:

Problem	When a service capability requires that consumers interact with it synchronously, it can inhibit performance and compromise reliability.
Solution	A service can exchange messages with its consumers through an intermediary buffer, allowing services and consumers to process messages independently by remaining temporally decoupled.
Impacts	There may be no acknowledgment of successful message delivery, and atomic transactions may not be possible.

 

Problem: Synchronous communication requires an immediate response to each request, and therefore forces two-way data exchange for every ...
