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 systemby
the same amount added by the same server. This ability is labeled as
redundancy. Redundancy are usually obtained through load balancing (load
balancing).
