The server Load balancer device allows you to easily expand a web server to a Web server cluster (provided that all Web servers must be configured completely the same, the device will send the request accordingAlgorithmTo a server in the web server cluster, which greatly increases the concurrent processing capability of the Web server. In practical applications, multiple Web servers are usually deployed i

Although the previous LVS have been configured successfully and load balanced, we found that when a real server stopped the Nginx process, the Director would still forward the request to the past, which caused some requests to be abnormal. So there needs to be a mechanism to detect the state of real server, which is keepalived. In addition to detecting the RS State, it can also detect the state of the standby director, that is, keepalived can implemen

When Server Load balancer is enabled, the CPU usage of svchost.exe is too high, leading to slow system exceptions. There are many problems with the high CPU usage of svchost.exe on the Internet.Article, Basically speaking about the vast majority of users and providing solutions. I will reference an article about this svchost on the Internet for you to see, if

First of all, we must acknowledge that from the perspective of this development preview, Win8 has made great breakthroughs in both technology and interface. It can be said that it fully demonstrates Microsoft's powerful desktop technology. New development tools allow almost allProgramDevelopers develop applications for Win8, from traditional C/C ++ to C # And even Web JavaScript, moreover, programs written in C # Or javascript can run on x86 and ARM hardware platforms; the concept of "content as
