Dynamic Elasticity: Cloud Computing

The increasing use of computing machine in our daily lives, and our more and more dependence on computing machine has always created a new demand for better, capacity and workload over time in machine which can help in making our decision better. Cloud computing refers to on demand delivery of IT resources and applications via the internet with pay as you go pricing. Cloud computing provides a simple way to access servers, storage, data bases and a broad set of applications services over the internet. Dynamic elasticity is a particular cloud layer which can automatically adapts its capacity to workload over time. Elasticity is one of the major requirement for increasing cloud computing operations and its uses resources in elastic manner. Load balancing of virtual machine is a challenging task in cloud environment due to the dynamic in nature. The help of dynamic elasticity we can easily increase the workload of a computing machine, and also we can reduce the cost and increase the quality as well as quantity. Auto scaling phenomenon, help us to maintain applications availability and allows us to scale our AMAZON EC2 capacity up or down automatically. Auto scaling use automatically increases the number of AMAZON EC2 instances during demand.
