Eclipse Zenoh is a unified data protocol and infrastructure that seamlessly blends publish/subscribe, distributed storage, queries, and compute into one system. It is designed for extremely efficient communication across edge, fog, and cloud environments, supporting both data in motion and data at rest. Zenoh uses a Rust-based implementation for high performance and low latency, and supports plugins for REST APIs, geodistributed storage management, and security. It is widely applicable in real-time IoT systems, robotics, and smart agriculture, especially where time-sensitive and distributed processing is required.
