中文摘要: 微服务架构逐渐成为构建复杂业务系统时的主流架构,但同时系统架构变得更加复杂,服务质量的保障成为一个关键的问题.本文围绕微服务架构下服务质量保障展开研究,通过熔断、降级、多路调用等方式解决服务调用过程中出现的各种问题.提出了微服务调用参数的计算模型,以实时的业务和设备监控数据为基础,对服务调用参数的精细化计算,并支持在线的动态参数调整.通过优雅停机和流量预热方法,解决了服务重启过程中出现的质量抖动问题.本文所提出的方法和模型,在实际应用中得到了充分验证,响应时间、失败率等指标大幅降低,使微服务架构下的系统更加稳定可靠的运行.
中文关键词: 微服务  服务质量  稳定和可靠
Abstract:Micro-service architecture has gradually become the mainstream architecture for building complex business systems, but at the same time, the system architecture has become more complex, and the quality of service assurance becomes a key issue. This study focuses on the quality of service assurance under the micro-service architecture, and solves various problems in the process of service invocation by fusing, degrading and multi-channel invocation. Based on real-time monitoring data of business and equipment, a calculation model of service invocation parameters is proposed, which can refine the calculation of service invocation parameters and support online dynamic parameter adjustment. Through the elegant shutdown and flow preheating method, the quality jitter problem in the process of service restart is solved. The method and model proposed in this study have been fully validated in practical application. The response time and failure rate are greatly reduced, which makes the system run more stably and reliably under the micro-service architecture.
