基于Sentinel的服务流控研究与应用

Research and Application of Service Flow Control Based on Sentinel

为满足Web应用可靠性、高并发、低耦合以及系统可快速开发的需求,微服务架构应运而生。在微服务架构中,服务自身的稳定性、服务与服务之间的稳定性尤为重要,而流量控制技术作为保证服务稳定性的一种重要手段,被广泛应用。笔者提出了基于Sentinel的服务流控技术的解决方案,通过基于QPS和并发数等流量控制技术的设计和改进应用,实现服务模块的自我保护,提升微服务架构的稳定性和可靠性。

In order to meet the requirements of Web Application reliability,high concurrency,low coupling,and rapid system development,the microservice architecture came into being.In the microservice architecture,the stability of the service itself,and the stability between the service and the service are particularly important,and the flow control technology is widely used as an important means to ensure the stability of the service.The author proposes a solution based on Sentinel’s service flow control technology.Through the design and improved Application of flow control technologies such as QPS and concurrency,the self-protection of service modules is realized and the stability and reliability of the microservice architecture are improved.
