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,

Haproxy works in the user space (Layer 7) and can identify data at the application layer (HTTP packets. Therefore, you can schedule requests to different service groups based on different request types. That is, haproxy can identify the request information of HTTP packets for access control; For example: A group of servers Process Dynamic Resources: JSP and PHP A group of servers process static resources, s

The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and medium-sized Web applications, such as the daily PV less than 10 million, with Nginx can be completely; if there are many machines, you can use DNS polling, LVS consumes more machines or more, large web sites or important services, and the server is relatively long, You can consider using LVS.One is through the hard

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 of thousands of concurrent connections altogether. and its operating mode makes it easy and secure to integrate into your current architecture while protecting your Web server from being exposed to the networ

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon
