ZeroMQ is a library used to implement messaging and communication systems between applications and processes - fast and asynchronously. If you have past experience with other application messaging solutions such as RabbitMQ, it might come a little bit challenging to understand the exact position of ZeroMQ. When compared to some much larger projects, which offer all necessary parts of enterprise messaging, ZeroMQ remains as just a lightweight and fast tool to craft your own. ZeroMQ Socket Types ZeroMQ differs in the way its sockets work. Unlike the synchronous way the regular sockets work, ZeroMQ’s socket implementation “present an abstraction of an asynchronous message queue”. The way these sockets work depend on the type of socket chosen. And flow of messages being sent depend on the chosen patterns, of which there are four: Request/Reply Pattern: Used for sending a request and receiving subsequent replies for each one sent.
