EMQ vs ZeroMQ: What are the differences?

Introduction:

1. Scalability: EMQ is designed for horizontal scalability with support for clustering, while ZeroMQ relies on a single process for each endpoint, making it less suitable for large-scale deployments.

2. Protocol Support: EMQ supports a wide range of protocols including MQTT, CoAP, and LwM2M, while ZeroMQ primarily focuses on the ZeroMQ protocol for messaging.

3. Architecture: EMQ is built on a modular architecture with a scalable message broker at its core, whereas ZeroMQ is a lightweight messaging library that requires users to build their own messaging patterns on top of it.

4. Features: EMQ offers advanced features such as message queue management, fine-grained access control, and real-time data processing, which are not as prominently featured in ZeroMQ.

5. Language Support: ZeroMQ provides language bindings for multiple programming languages including C++, Python, and Java, while EMQ primarily focuses on its core implementation without extensive language support.

6. Community and Ecosystem: ZeroMQ has a large and active community with a rich ecosystem of third-party tools and libraries, while EMQ may have a smaller community presence with fewer resources available for support and development.

In Summary, the key differences between EMQ and ZeroMQ lie in scalability, protocol support, architecture, features, language support, and community ecosystem.
