MESSAGE QUEUE BENEFITS
ABSTRACT

Message queues provide communication and coordination for these distributed applications

Better Performance​

  • MQs enable asynchronous communication
  • Reduces stalling / waiting

Increased Reliability​

  • Makes data persistent
  • Reduce the errors that happen when different parts of your system go offline and hence increases fault tolerance

Granular Scalability​

  • Allow for scaling where needed

Can scale consumers / producers / queue itself if necessary

  • Requests can be added to the queue without risk of collisions

Simplifed Decoupling​

  • remove dependencies between components
  • Significantly simplify the coding of decoupled applications

Break Up Apps​

  • Can be used to decouple your monolithic applications
INFO

Rather than performing multiple functions within a single executable, multiple programs can exchange information by sending messages between processes, making them easier to test, debug, evolve and scale

Migrate to Microservices​

  • Microservices integration patterns that are based on events and asynchronous messaging optimize scalability and resiliency
  • MQ services can coordinate multiple microservices, notify microservices of data changes, or as an event firehose to process IoT, social and real-time data.

Shift to Serverless​

Once you've built microservices without servers, deployments onto servers, or installed software of any kind, you can use message queues to provide reliable, scalable serverless notifications, inter-process communications, and visibility of serverless functions and PaaS.
