F5 Big-IP provides 12 flexible algorithms to distribute all traffic evenly to each server, while facing the user, just a virtual server?Ii? F5 big-IP can confirm that the application can return the corresponding data to the request? If the service stops on one of the servers behi

I. LVS principles 1. The full name of LVS is Linux Virtual Server, that is, Linux Virtual Server. It is an open-source project of Dr. Zhang Wenyu from our country. In linux memory 2.6, it has become a part of the kernel. in earlier versions, the kernel needs to be re-compiled ., LVS is mainly used for multi-server load balancing. It works at the network layer to implement high-performance and high-availability server cluster technology. It is cheap an

LVS Cluster has DR, TUN, Nat three configuration mode, can be the WWW service, FTP services, mail services, such as load balancing, the following through the construction of the WWW service load Balancer instance, describes the DR model based on the LVS cluster configuration.First, the configuration of Director serverThere are two ways to

Apache implements the Load balancer parameter "proxypass/balancer://proxy/", where "Proxypass" is the command that configures the virtual server, "/" represents the URL prefix for sending Web requests, such as: http://myserver/Or HTTP://MYSERVER/NODE1, these URLs will conform to the above filter conditions, "balancer:/

Load Balancing is built on the existing network structure, it provides a cheap, effective, and transparent method to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability. I have recently learned many articles about Server Load balancer technology on

Remember that there is a question in NP about the non-equivalent Server Load balancer of China. The answer is controversial. Today, I'm going to verify the non-equivalent Server Load balancer of the network. First of all, the non-equivalent Server Load

This article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu14.04.2LTS, two CentOS containers, Nginx for the host machine, and tomcat 7 for the two containers. The architecture is as follows: the principle of this solution is to map the host machine port and the docker container port (that is, a port accessing the host
