RabbitMQ vs ZeroMQ: 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 ZeroMQ? Fast, lightweight messaging library that allows you to design complex communication system without much effort. The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.

RabbitMQ and ZeroMQ belong to "Message Queue" category of the tech stack.

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, ZeroMQ provides the following key features:

  • Connect your code in any language, on any platform.
  • Carries messages across inproc, IPC, TCP, TPIC, multicast.
  • Smart patterns like pub-sub, push-pull, and router-dealer.

"It's fast and it works with good metrics/monitoring" is the primary reason why developers consider RabbitMQ over the competitors, whereas "Fast" was stated as the key factor in picking ZeroMQ.

RabbitMQ and ZeroMQ are both open source tools. It seems that RabbitMQ with 5.88K GitHub stars and 1.73K forks on GitHub has more adoption than ZeroMQ with 5.28K GitHub stars and 1.56K GitHub forks.

reddit, 9GAG, and CircleCI are some of the popular companies that use RabbitMQ, whereas ZeroMQ is used by SocialDecode, Binary.com, and Pixotale. RabbitMQ has a broader approval, being mentioned in 921 company stacks & 532 developers stacks; compared to ZeroMQ, which is listed in 35 company stacks and 12 developer stacks.

What are some alternatives to RabbitMQ and ZeroMQ?
Kafka
Kafka is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system, but with a unique design.
ActiveMQ
Apache ActiveMQ is fast, supports many Cross Language Clients and Protocols, comes with easy to use Enterprise Integration Patterns and many advanced features while fully supporting JMS 1.1 and J2EE 1.4. Apache ActiveMQ is released under the Apache 2.0 License.
Amazon SNS
Amazon Simple Notification Service makes it simple and cost-effective to push to mobile devices such as iPhone, iPad, Android, Kindle Fire, and internet connected smart devices, as well as pushing to other distributed services. Besides pushing cloud notifications directly to mobile devices, SNS can also deliver notifications by SMS text message or email, to Simple Queue Service (SQS) queues, or to any HTTP endpoint.
Redis
Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
Gearman
Gearman allows you to do work in parallel, to load balance processing, and to call functions between languages. It can be used in a variety of applications, from high-availability web sites to the transport of database replication events.

Reviews of RabbitMQ and ZeroMQ
Review ofRabbitMQRabbitMQ

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.
