What is RabbitMQ?
RabbitMQ is a well-known, open-source message broker for building distributed applications. Its design, features, and performance are distinct from other message brokers. A message broker serves as the middleman for different services that make up a web application. When some tasks take too much time or resources, message brokers can delegate such tasks to a free third party, which reduces delivery times and loads on the web application servers. Messages, on the other hand, can be any data. For instance, they can have data about a task or process that should start on another application on the same server or even on another server. The message broker keeps the messages in its storage while waiting for receiving applications to connect and takes them off the queue one by one for processing or execution.
As a message broker, RabbitMQ implements the Advanced Message Queuing Protocol (AMQP) principle, which provides several functionalities, such as message durability, message routing, and the publish/subscribe method. RabbitMQ has a centralized architecture, which means that message routing is done through a central message broker. The consistency and correctness of RabbitMQ make it a highly reliable system. Conversely, most other message brokers use a ...
