It is believed that cloud computing uses all the assets to calculate a utility exploitation virtualization techniques and communicate with grids for data communication. this provides the pliability to run a package on grid of method devices at constant period, whereas method unit on a private basis working on a collection of dataset. The principal of those problems is in fact linked to Capacity leveling subject, wherever the capacity is of the many kinds like load on the method unit, load on the network, load on the memory etc. Load leveling is that the tactic of distributing the capacity above the grid between varied nodes among the spread grid to urge the cause the minimum achievable time additionally on utilizing the assets at their most. among the items where variety of the nodes area unit heavily loaded, whereas totally different nodes do not appear to be being utilized or not being utilized to their most capability makes a state of affairs of restriction in Cloud accountable for every delay in latency of the facility additionally incompetent usage of cloud assets. Load equalization ensures that each one the offered resources square measure being employed within the approach that their most consumption of assets is going down. during a homogenous system load equalization is simple to accomplish since all the assets will be allotted same quantity of labor and that they can reply in nearly same time
