Cloud computing is internet-based ( " cloud " ) development and use of computer technology (“computing") It is a style of computing in which IT-related capabilities are provided “as a service” Allowing users to access technology-enabled services from the internet ("in the cloud") without knowledge of, expertise with, or control over the technology infrastructure that supports them. Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and cached temporarily on clients

It is a style of computing in which IT-related capabilities are provided “as a service”

Allowing users to access technology-enabled services from the internet ("in the cloud") without knowledge of, expertise with, or control over the technology infrastructure that supports them.

Processing 1000x more data doesn’t haveto be 1000x harder Cycles and bytes, not hardware, are the new commodity To address scalability and availability concerns for large scale applications Democratized distributed computing

The majority of cloud computing infrastructure currently consists of reliable services delivered through next-generation data centers The services are accessible anywhere in the world Open standards and open source software are also critical to the growth of cloud computing Commercial offerings need to meet the quality of service requirements of customers

As customers generally do not own the infrastructure, they are merely accessing or renting, they can forego capital expenditure and consume resources as a service. The services are accessible anywhere in the world Many cloud computing offerings have adopted the utility computing or subscription basis By sharing computing power between multiple tenants, utilization rates can be improved (as servers are not left idle) which can reduce costs significantly while increasing the speed of application development

Grid Computing is a form of distributed computing composed of a cluster of networked, loosely-coupled computers, acting in concert to perform very large tasks Indeed many cloud computing deployments are today powered by grids, but cloud computing can be seen as a natural next step from the grid-utility model. Some successful cloud architectures have little or no centralized infrastructure or billing systems whatsoever including peer to peer networks like Bit Torrent and Skype
