ZeroMQ

ZeroMQ (or ØMQ) is a high-performance messaging library that enables different computer programs or parts of a system to communicate quickly and efficiently. Unlike traditional network protocols, ZeroMQ provides a flexible way to connect components across a network or within a single machine, supporting patterns like request-reply or publish-subscribe. It handles message delivery, queues, and connections automatically, allowing developers to focus on designing their applications without worrying about low-level networking details. Essentially, ZeroMQ acts as a streamlined, reliable messaging backbone that facilitates real-time data exchange in complex systems.
