It mainly uses traffic as the entry point, from traffic control, traffic shaping, dependency isolation, circuit breaker downgrade, system adaptive overload protection, hotspot prevention and control, etc. A dimension to help developers ensure the stability of microservices. Sentinel has undertaken the core scenarios of Alibaba's Double Eleven in the past 10 years, such as spikes, cold starts, message peak shaving and valley filling, cluster traffic control, and real-time fuse downstream unavailable services, etc. It is to ensure the high availability of microservices It supports Java/Go/Rust/C++ and other languages natively, and provides Istio/Envoy/MOSN global flow control support to provide high-availability protection for Service Mesh.
