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

Hardware-level load balancing This load balancing is done through hardware, and common hardware has more expensive commercial load balancer

Implement website Load Balancing Based on Software (1) [Author: mid-season addition time: 06:09:01] Source: www.ccidnet.com Every website wants the system to be highly efficient and easy to scale. However, when combined with complex devices, it often requires expensive capital investment, which is hard to afford. Currently, multiple relatively inexpensive servers are used to solve the above
