There are many load balancing algorithm has been proposed for cloud computing in last decade but none of algorithm provides the elasticity with load balancing. We proposed a cloud architecture that is capable of handling the maximum user request before meet to deadline and provides an elasticity mechanism with the help of threshold based trigger strategy. Computational results (Table 1 & Figs. 2-5) shows that develop algorithm decrease the makespan time and enhance task acceptance ratio more than 10% compare to min-min algorithm, 30% compare to First come first serve (FCFS) and shortest job first (SJF) in all condition.
