Cloud computing is a style of computing in which virtualised and standard resources, software and data are provided as a service over the Internet.
Consumers and businesses can use the cloud to store data and applications, and can interact with the Cloud using mobiles, desktop computers, laptops etc. via the Internet from anywhere and at any time.
The technology of Cloud computing entails the convergence of Grid and cluster computing, virtualisation, Web services and Service Oriented Architecture (SOA) - it offers the potential to set IT free from the costs and complexity of its typical physical infrastructure, allowing concepts such as Utility Computing to become meaningful.
Key players include: IBM, HP, Google, Microsoft, Amazon Web Services, Salesforce.com, NetSuite, VMware.
