Market-Oriented Cloud Computing: Vision, Hype, and Reality of Delivering Computing as the 5th Utility

Abstract

Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision and they include Grid computing, P2P computing, and more recently Cloud computing. The latter term denotes the infrastructure as a “Cloud” in which businesses and users are able to access applications from anywhere in the world on demand. Hence, Cloud computing can be classed as a new paradigm for the dynamic creation of next-generation Data Centers by assembling services of networked Virtual Machines (VMs). Thus, the computing world is rapidly transforming towards developing software for millions to consume as a service rather than creating software for millions to run on their PCs.
