, sizes, and services provided in multiple server farms, it is possible to consider the most appropriate load balancing method for each server farm. Then again load-balancing or clustering among the multiple server farms to provide services to the outside world (i.e., as a new server farm) for optimal performance. This approach is called hybrid load balancing.This approach is sometimes used in situations where the performance of a single equalization device does not satisfy a large number of con
