Utility computing is envisioned to be the next generation of Information Technology (IT) evolution that depicts how computing needs of users can be fulfilled in the future IT industry. Its analogy is derived from the real world where service providers maintain and supply utility services, such as electrical power, gas, and water to consumers. Consumers' providers the services based on their usage. Therefore, the underlying design of utility computing is based on a service provisioning model, where Consumers pay providers for using computing power only when they need to. This chapter first discuss some features, challenges and impacts of utility computing. Finally this chapter point out the important, standards and recommendation of utility computing in cloud platform with a suitable example.
