• • Cost Reduction:Cost Reduction: Cloud computing follows a model in which Cloud computing follows a model in which service costs are based on consumption and make use of highly service costs are based on consumption and make use of highly shared infrastructure. Companies pay for only what they use and shared infrastructure. Companies pay for only what they use and providers can spread their costs across multiple customers. In providers can spread their costs across multiple customers. In addition to deferring additional infrastructure investment, IT can addition to deferring additional infrastructure investment, IT can scale its budget spend up and down just as flexibly. This leads to an scale its budget spend up and down just as flexibly.
