Apache Kafka - which is a distributed streaming platform that supports the pub/sub mode of interaction.RabbitMQ - which is open-source and provides asynchronous messaging capabilities.Amazon Simple Queue Service - which is the focus of this article.Here are some examples of popular message queues or brokers: When the time comes and the response is required, the service can look for the response in the message queue. This means that the loosely coupled systems do not have to wait for immediate feedback on the messages they send and they can be freed up to continue handling other requests. Message queueing is a mechanism that allows components of a system to communicate and exchange information in an asynchronous manner. The messages can contain anything - such as instructions on what steps to take, the data to act upon or save, or asynchronous jobs to be performed.
Messages are put in a queue and the target services pick up and act on the ones addressed to them. Message queueing facilitates this process by acting as the "post office service" for microservices. When a system is broken down into smaller components or services that are expected to work together, they will need to communicate and pass around information from one service to another, depending on the functionality of the individual services. People entrusted intermediaries to deliver their messages for them as they went ahead with their lives. This might have differed from region to region but the idea was the same. The letters contained the messages to be shared and were posted at the local post office station from where they would be transferred to the recipient's address. What is Message Queueing?īefore the internet and email came into the picture, people over long distances communicated mostly through the exchange of letters. In this post, we will dive into queueing systems, particularly Amazon's Simple Queue Service and demonstrate how we can leverage its features in a microservice environment. It is in these microservice architectures that Queueing Systems come in handy to facilitate the communication between the separate services that make up the entire setup. The loose coupling provides agility and eases the process of maintenance and the addition of new features without having to modify entire systems. This paved the way for microservices that allowed massive monolithic systems to be broken down into smaller services that are loosely coupled but interact to deliver the total functionality of the initial monolithic solution.

This increase in the complexity of systems made it harder to maintain, update, and upgrade them.

With the increased complexity of modern software systems, came along the need to break up systems that had outgrown their initial size.
