Load balancing is defined as the methodical and efficient distribution of network or application traffic across multiple servers in a server farm.
Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.
Load balancing uses advanced multilayer switching technology to provide real-time monitoring of server performance and health . According to the health of different servers, the data traffic of the visitor is allocated to the appropriate server in the most economical and efficient manner
In this way, the load of each server can reach a relative balance, so that the resource sharing of the relevant data receiving device is optimal, the response time is short, the processor runs faster, the data exchange amount is greatly improved, and the operation efficiency is qualitatively leap.
