ADVANTAGES AND DISADVANTAGES OF PUB/SUB
ADVANTAGES Loose Coupling Publishers do not know about the existence of the subscribers so that both systems can operate independently of each other. By this method, the service dependencies which are present in traditional coupling are completely abolished. A Publisher doesn’t need to know about - They will be able to work independently and this will allow them to develop both separately without worrying about any number of ripple effects, states, or implementation. Scalability Pub/sub messaging will scale to volumes beyond the limited capabilities of a single traditional data-gathering center. This level of unprecedented scalability is primarily due to parallel operations, message caching, tree-based routing, and multiple other features built into the pub/sub model. But for all its advantages, Scalability has a limit. If the number of nodes and messages are increased, then the chances of experiencing a load surge or slowdown increase
