Queue managers are systems that reliably handle communication and data exchange between services, one of the most popular queue managers is RabbitMQ.
When data traffic becomes intense or a service takes a lot of time to complete its tasks queue managers become an essential brick in the architecture of the platform RabbitMQ is a message-queueing software called message broker or queue manager, it handles received messages and delivery the message to a software that are waiting for messages, it also store the messages into a queue until a receiving application connects and takes a message off the queue.
The architecture of a message queue is simple, an application called producer can create a message and send it to Queue Manager, and other application called consumer connect to Queue Manager and wait for receive message.
Message queueing allows web servers to respond to requests quickly instead of take much time to process data. Message queueing is also good when you want to balancing loads between workers or when you want distribute a message to multiple recipients for consumption.
Messages are not pushed directly to a queue, instead, the producer sends messages to an exchange that it’s responsible for the routing of the messages to the different queues. An exchange accepts messages from the producer application and routes them to message queues with the help of bindings and routing keys.
