I) How does cloud computing work? How did it come about? Where is it going in the future? II) How does it affect people and businesses: What is its value? What negative impact does it have? III) Which companies will sell it and what is the nature of the business? IV) Does government need to control this new technology? Why ? V) Opinion about Cloud computing.

IN 2009 The Cloud Security Alliance declared that the “cloud describes the use of a collection of services, applications, information, and infrastructure comprised of pools of compute, network, information, and storage resources. These components can be rapidly orchestrated, provisioned, implemented and decommissioned, or scaled up and down (Rapid elasticity ) ” . Indeed cloud computing is used by people; they use computing resources ( hardware and software ) delivered on the internet ( over a network ) and reachable through heterogeneous devices ( Broad network access) . End users can access cloud based applications via the internet while the business software and user’s data are stored on servers . Thus, All they can see are “front-end layers “ ,that is, interfaces that people see and interact with ., these very layers need to be fuelled, though . That’s the role of “back-end layers”, they consist of the hardware and the software architecture .

Globalization explains the use of cloud computing : nowadays, people need to have access to information from everywhere ( either in management or in personal life ). Moreover data increasing-complexity ( as data volume keeps increasing ) made cloud computing very interesting, as well as the possibility to reduce hardware expenses . Indeed, the potential for cost savings is a key factor in the equation. In the 2010 Global Information Security Survey, Ernst and Young (2010) found organizations searching for ways to reduce IT expenditures without sacrificing technological advantages, stating: “Their interest lies in computing services that require significantly less initial investment”

Cloud computing mainly developed thanks to the improvement of virtualization technology, the development of universal high-speed bandwidth and universal software interoperability standards. A milestone came in 2009, as Google and others started to offer browser-based enterprise applications, through services such as Google Apps.

Cloud computing has a promising future .Indeed, not only does it reduce capital expenditures, it also shrinks energy consumption and carbon emissions . It is said that , by 2020, U.S. organizations that move to the cloud could save $12.3 billion in energy costs and the equivalent of 200 million barrels of oil.The business figures come along too. In 2009, revenue for cloud services was just over $58.6 billion. In 2011, IT spending is expected to top $2.6 trillion. Thus, The research firm Gartner projects that revenue for cloud services will approach $152.1 billion in 2014.

A research from the London School of Economics based on a survey of more than 1000 businesses and IT executives explains that cloud computing will have an impact on the majority of organizations. 20% of this poll is already using cloud services and another 20% is planning a transition in the next 18 months. We can see that Cloud Computing is rapidly being adopted in a lot of organizations. Whether it provides a value or becomes a threat, the Cloud system is deeply...
