Load balancing algorithms in heterogeneous web cluster

The load balancing is dedicated for distributed and parallel systems to manage the web cluster. It distributes the load among web servers using several scheduling algorithms. This paper investigates a detailed comparison of some HAProxy algorithms in heterogeneous web cluster as well as the meta-heuristic methods that inspired by the insects' colonies behavior such as Ant Colony Optimization algorithm and Honey Bee algorithm. The basic idea of meta-heuristic methods is to solve combinatorial optimization problems.
