RabbitMQ Alternatives and Free Competitors 2021


RabbitMQ is one of the famous messaging brokers, acting as a mediator for messaging. It has a slightly flexible messaging system, and it also acts as a multipurpose broker. The software provides a platform to send and receive messages. Moreover, the software also provides a safer place for your message to live until they are received. 

The software is open source and works quite conveniently by accepting messages from producers and sending them to consumers. In other words, Rabbit MQ acts as a go-between, used to lessen the web application server took loads as well as delivery times. 

Steps for Producers to Send Messages. 

To be able to produce a message, the following steps should be followed.

  • First of all, the producer is supposed to create a connection with the Queue. 
  • ConnectionFactory factory= new ConnectionFactory(); 

factory .setHost(“localhost’)’// IP of the machine Connection connection= factory.newConnection(); 

Channel channel= connection.createChannel ();

  • The second step would be specifying the queue’s name to which the user intends to send messages and publish messages to the queue. 


String message = “Hello World!”;

channel.basicPublish(“”, QUEUE_NAME, null, message.getBytes());

  • 3) Finally close channel and connection. 

How can Consumer Recieve a Message?

When the Producer sends a message, he has done his part; the next step is to receive the message. So, to be able to receive a message, a consumer should be following these steps. 

  • First of all, consumers should create a connection to Queue. 
  • Next, the need to specify the queue’s name, which he thinks should consume his messages. 
  • As it is known that the queue sends a message asynchronously, a callback is provided in the form of an object that buffers the messages until the consumer is ready to use it, 

Consumer consumer = new DefaultConsumer(channel)

If you have two consumers connected to one queue, both of them will have the opportunity to get tasks from the queue. The method RabbitMQ takes up for distributing messages in a round-robin manner implies that it sends each message to the other Consumer in order. Normally, each Consumer manages to get the same number. 

As soon as the message is delivered to a consumer from the queue, RabbitMQ takes it down. So, what would be the circumstances in any untoward circumstances, such as if the worker passes away or has to leave, leaving half work undone? So, do not worry; RabbitMQ has it covered. To be able to handle it, there is an option available, “acknowledgment.” On this option, an ack is sent back directly from the Consumer to inform RabbitMQ about a specific message that has been received as well processed. After that, RabbitMQ is free to delete it. 

RabbitMQ Alternatives

There are times when during the task distribution when a few messages are too heavy and need more time in comparison to odd messages. In such a case, normally, one worker is continually busy while the other worker rarely gets to do anything. So, in such situations, it is recommended to use:

no prefetchCount = 1;


Using it will make it certain that RabbitMQ will not deliver more than one task to one worker, so there remains a balance. This way, RabbitMQ will check for acknowledgment from workers and will not dispatch the latest message to a worker until the previous one is not processed. If one worker is not done with the message yet, RabbitMQ will send the message to another worker who would not be working at that time. 

RabbitMQ Exchange

RabbitMQ actually works by making the producer send a message to Exchange and then exchange pushes it to other multiple queues. Later on, the workers receive messages from several queues with which RabbitMQ has binded with. 

However, instead of publishing the messages directly to the queue, the producers now rather than publishing messages to exchange. Later on, the Exchange delivers messages to queues based on exchange types. The types are direct, topic, and fanout. 

While publishing messages to exchange, the producer has to ensure the type of exchange he is going to use. For example, he can use:

channel.exchangeDeclare(“logs,” “fanout”); //logs are the name of the fanout exchange

channel.basis publish( “logs”, “”, null, message.getBytes()); //publish message to exchange

This relation between the exchange and the queue is called binding. 

  • Fanout Exchange: The Fanout exchange broadcasts all the messages it receives to the queues it is aware of. This form of exchange ignores the binding value as it forwards the messages to all queues. 
  • Direct Exchange: In the Direct exchange, messages go to those specific queues whose binding key matches the message’s routing key. 
  • Topic Exchange: Topic exchange works similarly to the direct exchange, but the routing based on multiple criteria is different.

  • Reliability: RabbitMQ renders a great variety of features to allow users to trade off performance within complete confidentiality, persistence, delivery acknowledgment, and high availability. 
  • Flexible Routing: It offers flexible routing. If you want a somewhat more complex routing, you have the option of binding exchanges together. 
  • Clustering: RabbitMQ enables different servers on a local network to form a cluster to create a single logical broker. 
  • Federation: RabbitMQ also has to offer a federation model for servers that require to be loosely and unreliably connected. 
  • Multi-protocol:mRabbitMQ is known for supporting messaging over a variety of different messaging protocols. 
  • Many Clients:mThere are several RabbitMQ clients for almost every language people speak. 
  • Management UI: The competent and easy-to-use management UI allows users to monitor and control different aspects of the message broker. 
  • Tracing: If the messaging system does not work well, RabbitMQ renders tracing support to allow you to investigate the problem. 
  • Plugin System:mRabbitMQ offers to ship with several plugins by extending it in different ways. Also, it allows you to create your plugins. 
  • Commercial Support:mCommercial support, training as well as consulting are also available at the RabbitMQ from Pivotal. 
  • Large Community: RabbitMQ caters to a relatively large community that produces clients, plugins, guides, and much more. You can be a part of it simply by joining the mailing list. 


RabbitMQ is known for its flexibility and the convenience it offers while sending and receiving a message. Despite all the fantastic features, the software has some loopholes that are hard to resist. Here are some of the cons. 

  • The software often freezes and stops working, given its high latency. 
  • The deployment and management of RabbitMQ are not impressive.
  • The message shipment process is not reliable and is vulnerable to information loss. 
  • It refuses to be installed as modules and is only allowed to be installed on machines. 
  • RabbitMQ is hard to monitor
  • It is high maintenance.
