Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications to support virtual hosts, a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, which typically require session maintenance or seven-tier processing. Haproxy is running on the current hardware and can support tens o

Hproxy provides high availability, load balancing, and reverse proxies based on TCP and HTTP applications, especially for those web sites that are heavily loaded, which typically require session hold or seven-tier processing. Haproxy runs on the current hardware, fully supports tens of thousands of concurrent connections, and its operating mode makes it easy and secure to integrate into the architecture, while protecting your Web server from being exp

Objective Software load Balancing is generally implemented in two ways: operating system-based soft load implementation and soft load balancing based on third-party applications. LVS is a kind of soft load based on Linux operating system, while Haproxy is a soft load based on third party application. Haproxy compared to the use of LVS is much simpler, but like LVs, hapr
