Cloud computing!!, the future of computing?

What is cloud computing?

The “cloud computing” is a concept emerged relatively recently, but its beginnings go back a few years, especially in the technology of grid computing used for scientific computing.

Cloud computing refers to the use of memory and computing capabilities of computers and servers around the world, linked by a network, such as the Internet. Users of the cloud may well have a flexible and considerable computing power.

Cloud computing, a marketable product?

Yes, this technique is becoming a business. The entire computing power and memory, as a tool provided as a service to customers by a business is advertised by some professionals as the ultimate stage of the industrialization of data centers.

As like electric energy a few decades ago, power of computing and storage space of information would be available for usage by specialised organizations. As a result, organizations would no longer need to own hosts, but assured that source to a company that would ensure their power of computing and storage space on demand.

A software layer resource management and programming tools would also be proposed by the owners of cloud computing and what a way to make it usable by as many of these resources.

Similarly, operating systems could be offered at a distance. On this point, virtualization technologies, very much in vogue at present, could fit right in to the concept of cloud computing.

Amazon offers these tools S3 (Simple Storage Service) and EC2 (Elastic Compute Cloud), storage and computing power from her IT infrastructure for its customers.

In hardware, computing power and storage is no longer required locally or on the computer, it is likely that the thin client terminals may be sufficient to the needs of users. This new hardware offering could be as Haas (Hardware as a Service), that is to say that the material, inexpensive, could also be offered by companies to use package.

To some extent, SaaS (Software as a Service) is an annunciate of this new way of thinking and practice computer.

What are the advantages for the user?

As the use of IT infrastructure is considered a service, the client does not have to worry about the operation of it. In addition, the agility and flexibility of supply allows the user to have the computing power he wants when he wants, without having to buy power units and calculation that not used as it is today with computers and data centers owned businesses.

Cloud computing, end of the DSI?

With an offer outsourced information technology, business managers may be called upon to do without a DSI internally to appeal to an external provider. Still, the issues of privacy and quality of service against the cost of the service may be the subject of much attention from policy makers to choose or not to outsource the all of their resources.

Who are the actors who seize this concept and the technology?

Amazon was one of the first companies to offer through its tools S3 (Simple Storage Service) and EC2 (Elastic Compute Cloud) storage and computing power from her IT infrastructure for clients. The newspaper The New York Times is also client and uses Amazon S3 for its online archive.

Google is the champion of cloud computing. The company started its activities in this area with the Google project 101, and that in order to create a network between universities for research. Today, cloud computing project, in partnership with IBM, tends to create data centers, called clusters, of a power never hitherto achieved.

IBM, as part of its Blue Cloud program announced in November 2007, is now open centers continental cloud (the one for Europe is based in Dublin, Ireland). Three centers exist in the U.S., another is also installed in China and a second is in preparation.

Others should soon be made in Brazil, South Africa, India, the Arabian Peninsula, Vietnam and Korea. This is actually huge data centers, also called data fields, destined for users outside the company, which will be charged on the use of resources available to them.

And some large companies in the computer world have decided to take the plunge. Sun Microsystems has announced that by 2015, all data centers will be virtualized the company with third parties as part of a cloud.

Other actors, like EMC Corporation, actor infrastructure software, engage in strategies for growth and acquisition outsourced to develop cloud computing offerings. EMC to buy just such Pi Corporation, a young publisher of management solutions for personal information online, based in Seattle. HP in turn offers a printing service through its own cloud, called CloudPrint.

The research firm Forrester said that cloud computing should enter the corporate market by one or two years.
