gRPC Load Balancing 翻译自:https://grpc.io/blog/grpc-load-balancing/ 这是gRPC负载均衡的第一篇,后续会给出基于golang XDS服务发现的例子,了解golang XDS的工作原理. 本文描述了在部署gRPC时可能会采用的几种负载均衡场景. 大规模gRPC部署下,通常会有大量相同的后端实例以及大量客户端.由于每个服务的容量是有限的,因此会使用负载均衡在可用的服务器之间均衡来自客户端的请求. 目录 gRPC Load Balanci…

      最近配置SharePoint 2013 WFE 时,客户提到要让多台WFE能load balance,于是研究了下Network Load Balancing.       当把一台服务器(包括Web服务器.FTP服务器或者流媒体服务器等等)放入网络中之后,随着客户端数量的不断增加,人们往往需要功能更强大.处理速度更快的服务器.为了解决这个问题,如果将原有的服务器替换成功能更强大.处理速度更快的服务器显然并不是值得称道的办法.但是如果能把新服务器添加到原有服务器的处理能力基础上而不是…

概述 文章负载均衡(Load Balancing)学习笔记(一) 讲述了负载均衡的一般性原理,本文继续介绍常见的实现负载均衡的方法. HTTP重定向 HTTP重定向服务器是一台普通的Web服务器,用户的请求先到达重定向服务器,这台服务器会挑选一台后端服务器的地址(例如使用轮询的方式),并将该地址写入HTTP重定向响应结果中(以响应状态码302返回)返回给用户.用户将根据这个新的地址重新发送请求到选中的服务器上.选中的服务器会处理用户请求,并将结果返回给用户.HTTP重定向的处理流程如图1所示.图…

概述 在分布式系统中,负载均衡(Load Balancing)是一种将任务分派到多个服务端进程的方法.例如,将一个HTTP请求派发到实际的Web服务器中执行的过程就涉及负载均衡的实现.一个HTTP请求到达Web服务器,这中间涉及多个过程,也存在多种不同负载均衡的方法.本文讲述负载均衡的基本原理与派发策略,下图1是负载均衡的基本原理图,图1中客户端的请求请求经过达负载均衡器(Load Balancer)的分派,被指定的服务器进程进行处理.图1:负载均衡基本原理 实现负载均衡主要有两个目的.第一个目…
