什么是服务发现服务发现 指一个服务通过某种方式查找其他服务网络位置(如IP,端口号)等信息的过程。 为什么需要服务发现当一个服务与其他服务进行通信时,我们需要知道其他服务的网络位置(IP,端口号)信息。在传统的单体服务中,各个服务实例的网络位置是相对静态的,这样我们可以从偶尔更新的配置文件中读取各个服务的网络位置。但在微服务架构中,由于扩缩容、故障、升级等原因,服务实例的网络位置是动态分配和动态

性能测试是什么?性能测试是一个严谨的工程项目,在一个系统开发完成后,在功能测试,安全测试等之外,必须进行性能测试。性能测试主要统一考虑这么几个因素:吞吐量、响应时间、资源利用(CPU/MEM/IO/Bandwidth),成功率、系统稳定性. 并发数(cocurrency)系统同时处理的请求数 响应时间(latency)请求从接受到成功处理返回的耗时 吞吐量(QPS/TPS)吞吐量 = 并发数 /
