Advantages

Cloud computing using on sharing of resources to achieve communication over a network. Cloud computing is a concept of converged infrastructure and shared services. The cloud also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but as well as dynamically re-allocated as per demand. This can work for allocating resources to users in different time zones. The approach of cloud computing should maximize the use of computing powers thus reducing environmental damage such us less power etc.

Cloud computing allows companies to avoid upfront infrastructure costs and focus on projects in their businesses instead of infrastructure. cloud computing also allows enterprises to get their applications up and running faster,  improved manageability and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.
