Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand.
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link billions of devices worldwide.
Introduction to Cloud Computing by Eli the Computer Guy
It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources, which can be rapidly provisioned and released with minimal management effort.

Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in either privately owned, or third-party data centers that may be located far from the user–ranging in distance from across a city to across the world.
A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems.
Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility over an electricity network.
Advocates claim that cloud computing allows companies to avoid up-front infrastructure costs.
As well, it enables organizations to focus on their core businesses instead of spending time and money on computer infrastructure.
A business, also known as an enterprise, company or a firm is an organizational entity involved in the provision of goods and services to consumers.
Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables Information technology teams to more rapidly adjust resources to meet fluctuating and unpredictable business demand.
Information technology is the application of computers and internet to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise.
Cloud providers typically use a "pay as you go" model.
This will lead to unexpectedly high charges if administrators do not adapt to the cloud pricing model.
In 2009, the availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture, and autonomic and utility computing led to a growth in cloud computing.
Computer hardware virtualization is the virtualization of computers as complete hardware platforms, certain logical abstractions of their componentry, or only the functionality required to run various operating systems.
A service-oriented architecture is a style of software design where services are provided to the other components by application components, through a communication protocol over a network.
In computing, virtualization refers to the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources.
Companies can scale up as computing needs increase and then scale down again as demands decrease.
In 2013, it was reported that cloud computing had become a highly demanded service or utility due to the advantages of high computing power, cheap cost of services, high performance, scalability, accessibility as well as availability.
Some cloud vendors are experiencing growth rates of 50% per year, but being still in a stage of infancy, it has pitfalls that need to be addressed to make cloud computing services more reliable and user friendly.
