Cloud Computing, Load balancing, Scalability, Redundancy results Performance. Cheaper or a costlier an option is not the factor when performance is judged. An ideal system capacity increases linearly adding hardware. In this system, if a car have a 1200 cc cylinder, adding another will double it too 2400 cc and we are adding another should theoretically double our capacity. If instead we have three cars and we are working capacity is expected to increase by at least 50%. This ability is called scaling. From the point of view of an ideal system faults is not revolutionized by loss of a server. Losing a server should simply decrease the capacity of the system by the same amount added by the same server. This ability is labeled as redundancy. Redundancy are usually obtained through load balancing (load balancing).
