LOAD BALANCING IN CLOUD ENVIRONMENT: A REVIEW

An essential role of cloud computing platform is to dynamically balance the load among the different servers in order to?? improve resource utilization and to avoid hotspots. Load balancing (LB) is done on both sides i.e. on provider as well as on consumer side. On provider side, load balancing is the problem of allocating virtual machines to servers at runtime. Virtual Machine need to be reassigned so that servers do not get overloaded as demand changes. On consumer side application load can be balanced which provides efficiency to the consumers. On cloud computing platform, load balancing of the entire system can be? dynamically handled? by? using? virtualization? technology through which it? becomes? possible? to? remap? virtual? machine? and physical resources? according? to? the? change? in? load. However, in order to improve performance, the virtual machines have to fully utilize its resources and services by adapting to computing environment dynamically.? The? load balancing? with? proper? allocation? of? resources? must? be guaranteed? in? order? to? improve? resource? utility.
