ZeroMQ Tutorial

ZeroMQ is an high-performance, asynchronous, Open-Source, Universal Messaging Library aimed to be used in distributed or concurrent applications.

Distributed or concurrent applications are systems where components or services are spread across multiple network computers. These components work together to achieve a common goal but operate independently.

ZeroMQ can also be spelled or known as − MQ, 0MQ, or ZMQ. If you come across any of these variations, don't be confused, as they all refer to ZeroMQ. Though ZeroMQ is often described as Embeddable Networking Library, it will act as a concurrency framework.

Our ZeroMQ tutorial helps you learn ZeroMQ in simple and easy steps so that you can quickly use it in distributed or concurrent applications. It covers most of the important concepts related to ZeroMQ, providing a basic to intermediate understanding of ZeroMQ and helping you to pickup the advanced topics from there.

The Zero in ZeroMQ

The zero in ZeroMQ denotes, zero brokers (ZeroMQ is broker-less), zero latency, zero cost (it is free to use, no paid version needed), and zero administration.

Why to Learn ZeroMQ?

As we discussed earlier, ZeroMQ is an Open-source Universal Messaging Library and acts as a concurrency framework. It is especially advantageous for developers working on high-performance distributed or concurrent systems.

The ZeroMQ provides a lightweight messaging framework that enables efficient and scalable communication between different components of a distributed system. Below are key points highlighting the reasons for learning ZeroMQ −

  • High Performance
  • Broker-less Architecture
  • Scalability
  • Open-source and Cost-effective
  • Versatile Messaging Patterns

Used by Companies

Following is a list of famous companies that use the ZeroMQ messaging library for their distributed applications −

  • Microsoft
  • Samsung
  • Facebook
  • Bitcoin
  • Jupyter

Prerequisites to Learn ZeroMQ

Before proceeding with ZeroMQ, you should have the basic knowledge of the following technologies and fundamentals −

  • Basic Programming Knowledge
  • Networking Fundamentals
  • Basic Knowledge of Messaging Pattern
  • Concurrency and Parallelism
  • Familiarity with Development Tools
  • Understanding of Multi-threading (optional)
