The benefits of message queue software include:
1. Improved performance. Message queues enable asynchronous communication between and within apps. This means the endpoints that produce and consume messages interact with the queue and not with each other. Producers can add requests to the queue without having to wait for them to be processed, and consumers only process messages when they are available. In this way, neither component in the system has to wait for the other, which optimizes data flow.
2. More reliable. Queuing your data makes it persistent and reduces the risk of errors happening when parts of your system go offline. Separating different components into message queues creates fault tolerance. In addition, any time one part of the system is unreachable, the other part can continue interacting with the queue. The queue can also be mirrored, allowing for even more availability.
3. Granular scalability. Producers and consumers as well as the actual queue can be scaled on demand.
4. Simplified Decoupling. Using a message queue removes dependencies between components and simplifies the coding of decoupled applications. Software components can be designed to perform discrete business functions rather than being weighed down with communications code.
