RabbitMQ vs RSMQ: What are the differences?
What is RabbitMQ? A messaging broker - an intermediary for messaging. RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
What is RSMQ? A lightweight message queue for Node.js that requires no dedicated queue server. Just a Redis server. tl;dr: If you run a Redis server and currently use Amazon SQS or a similar message queue you might as well use this fast little replacement. Using a shared Redis server multiple Node.js processes can send / receive messages.
RabbitMQ and RSMQ can be primarily classified as "Message Queue" tools.
Some of the features offered by RabbitMQ are:
- Robust messaging for applications
- Easy to use
- Runs on all major operating systems
On the other hand, RSMQ provides the following key features:
- Guaranteed delivery of a message to exactly one recipient within a messages visibility timeout.
- Received messages that are not deleted will reappear after the visibility timeout.
RabbitMQ and RSMQ are both open source tools. RabbitMQ with 5.94K GitHub stars and 1.78K forks on GitHub appears to be more popular than RSMQ with 1.07K GitHub stars and 78 GitHub forks.

I developed one of the largest queue based medical results delivery systems in the world, 18,000+ queues and still growing over a decade later all using MQSeries, later called Websphere MQ. When I left that company I started using RabbitMQ after doing some research on free offerings.. it works brilliantly and is incredibly flexible from small scale single instance use to large scale multi-server - multi-site architectures.
If you can think in queues then RabbitMQ should be a viable solution for integrating disparate systems.
The poster child for scalable messaging systems, RabbitMQ has been used in countless large scale systems as the messaging backbone of any large cluster, and has proven itself time and again in many production settings.
Rabbit acts as our coordinator for all actions that happen during game time. All worker containers connect to rabbit in order to receive game events and emit their own events when applicable.
Used as central Message Broker; off-loading tasks to be executed asynchronous, used as communication tool between different microservices, used as tool to handle peaks in incoming data, etc.
RabbitMQ is the enterprise message bus for our platform, providing infrastructure for managing our ETL queues, real-time event notifications for applications, and audit logging.
