Fashion is fickle. One day thin clients and clusters are the fashion de jour, the next it's Web 2.0, Virtualisation or distributed computing and Grids. They who live by the sword of fashion will surely perish by it but a new model has been strutting its stuff along the catwalk of web fashion and she goes by the name of Cloud Computing.

2010 is definitely the year of the cloud, The IT world is abuzz with the benefits of cloud computing and rightfully so. Cloud computing, the logical extension of network storage and virtualization, is probably the biggest IT leap forward since pervasive use of the Internet. Despite the buzz all that glitters isn’t gold.

The total number of dollars rushing toward cloud computing is massive. The various top research firms - IDC, Gartner, et al. -- all have eyebrow-raising forecasts about the growth rate of cloud-based computing services. But are you seeing a lot of headlines about safety? No, not really, though the worries are out there.

"Cloud Computing risks undoing the gains of the free software movement in ‘owning and controlling our own code‘. Thomas Lord examines the potential for achieving software and user freedom in the world of ‘cloud computing’ (a concept he rejects, preferring ‘utility computing’, see below).

Web developers may believe that, in order to use cloud computing, they must accept limitations in the way they write and build their applications. But that view is a misconception; open standards for cloud computing are already in place and are being tweaked.

Cloud computing is a concept. It is an architectural framework by which one or many organizations can deploy, manage and retract any workload, public or private. Cloud computing addresses business needs from a workload perspective.

These days, everybody is talking about cloud computing, and many people use it in one form or the other. But popular cloud computing services are provided by a third party, which means that you store you data on a server somewhere, so that you can access it any time, from anywhere. But there are cloud applications that any person can use to host their own private cloud, from their home.

When Mark Shuttleworth announced the future Ubuntu 9.10 release, Karmic Koala, the goals he outlined for the server version were all to do with cloud computing but you might be asking "What is cloud computing ?" I answer this question and investigate what it can do for Ubuntu?

Clearly, the underlying technology of cloud computing will be based on open source software--that is, if the three cloud infrastructure hopefuls addressing a standing room-only crowd of more than 350 venture capital firms, large company CTOS and CIOs, and other cloud hopefuls--are as successful in their efforts as the show’s judges and audience anticipated.
