Cloud computing is the delivery of computing resources such as hardware, software, databases and more over the internet. It allows users to access technology-enabled services from any device on demand without direct management. Common types of clouds include public, private, community and hybrid clouds. While cloud computing provides scalability, cost savings and mobility, it also faces challenges regarding security, standardization and quality of service. Cloud adoption has grown significantly in recent years and is forecast to continue growing substantially faster than traditional IT.

What is Cloud Computing?
Definition:
Wikipedia:
Cloud Computing is the use of computing
resources (hardware and software) that are delivered as a
service over a network (typically the Internet).
Oxford Dictionaries:
Cloud computing is the practice of using a network
of remote servers hosted on the Internet to store, manage,
and process data, rather than a local server or a personal
computer.
Gartner:
Cloud computing is a style of computing in which
scalable and elastic IT-enabled capabilities are delivered
as a service using Internet technologies.
Forrester:
Cloud computing is a standardized IT capability
(services, software, or infrastructure) delivered via
Internet technologies in a pay-per-use, self-service way.
IDC:
Cloud computing is an emerging IT development,
deployment and delivery model, enabling real-time
delivery of products, services and solutions over the
Internet (i.e., enabling cloud services).
US National Institute of Standards and Technology (NIST):
Cloud Computing is a model for enabling convenient,
on-demand network access to a shared pool of configurable
computing resources (e.g. networks, servers, storage,
applications, and services) that can be rapidly provisioned and
released with minimal management effort or service provider
interaction.
