Introduction to load Balancing clusters
The software that realizes load Balancing cluster is: LVS, keepalived, Nginx, Haproxy and so on. The LVS belong to four layer (network OSI model), Nginx belongs to seven layer, haproxy can be considered as four layer, also can be used as seven layer.
The Keepalived load

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
