Web farm and Network Load Balancing overview After you make a Web Farm of multiple IIS Web servers within an enterprise, these servers provide a continuous, reliable Web server to users. When a web Farm receives a request from a different user to connect to a Web site, these requests are distributed to different Web servers in the Web Farm, thereby improving the efficiency of Web Access, if a Web server in

, often problems, rather than simple and stable. In the enterprise, more than 90% of the failure, from the demand change. It could be a bug, a human error, a schema design problem, and so on. Front-end load balancing equipment is the most important, in the software selection must be fully considered, to meet the premise of business, as far as possible to reduce complexity, improve serviceability.Project fou

1.HAProxy Introduction Haproxy is an open-source, high-performance, load-balancing software based on TCP (four-tier), HTTP (seven-tier) applications. That haproxy as a professional load balancer software, it has the following advantages: Very good reliability and stability, comparable to hardware-level F5

WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use F5 and other devices, software generally use Apache to achieve. Here's how to use Apache. WebLogic load Balancing can be achieved by means of software and hardware. Hardware can use

system. LVS operates on the fourth layer of the ISO model because it operates on the fourth layer, therefore, like iptables, it must work in kernel space. Therefore, like iptables, LVS directly works in the kernel, called ipvs. Mainstream Linux distributions have already integrated ipvs by default. Therefore, you only need to install ipvsadm, a management tool.Ipvs implements three load balancing technolog
