🧱 Architecture

Architecture

Communication between consumers and providers is done via RPC protocols like Triple, TCP, REST, etc.
Consumers dynamically discover provider instances from registries (e.g., Zookeeper, Nacos) and manage traffic using defined strategies.
Built-in support for dynamic config, metrics, tracing, security, and a visualized console.

🚀 Getting Started
