Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source and soft load based on the third application implementation.Haproxy compared to the use of LVS is much simpler, the function is also very rich. Currently,
