Cloud Computing

Introduction

The evolution of information technologies and means of communication is unstoppable and every day are made ??available to citizens with new tools solutions, and increasingly sophisticated and integrated with the Internet, allowing to meet growing needs of computerization and communication. In this framework, cloud computing is a set of service models more than others is spreading very rapidly among businesses, public administrations and citizens because it encourages flexible use of resources (infrastructure and applications) or those provided by a qualified service provider (Creswell, 2005). The innovation and success of the cloud (the cloud computing) is that, achieved thanks to the maturity of the technologies that form the basis, these resources are easily configurable and accessible via the network, and are characterized by particularly agility of use that on the one hand greatly simplifies the sizing Initial systems and applications while on the other, allows to support phased investment effort required for the appropriate adjustments technology and the delivery of new services. As part of cloud computing is now common practice to distinguish between private clouds and public clouds.

Cloud Computing: Directions For The Conscious Use Of Services

A private cloud (cloud or private) is an information infrastructure for the most dedicated to the needs of a single organization, located on its premises or contracted under management to a third party (in the traditional form of 'hosting server) against which the owner of the data can often exert a precise control. The private cloud can be compared to the traditional "data center" in which, however, are used for technological solutions that optimize the use of available resources and strengthen them through investment content and implemented progressively over time (Cooper, 2006).

In the case of public cloud, however, the infrastructure is owned by a supplier specializes in providing services that make available to users, companies or administrations - and then share with each other - their systems through the provision web of computer applications, processing power and storage. The fruition of these services is via the Internet and involves the transfer-eLab or just the data from the systems of the service provider, who assumes a role imported into the efficacy of the measures taken to ensure the protection of data that have been entrusted (Computer Language Company, 2008). In this case the user with the data, in fact, gives a important part of the control exercised over them. For example, the complexity of infrastructure, and their possible relocation sites outside the national borders may make it impossible to know both the exact location of their data in the cloud, is to know if and when data is moved from one place another for organizational, technical or economic difficult to determine and manageable in advance. Moreover, the size of the supplier could affect the strength contract of service users and their ability to exercise control direct, even if agreed, sites and infrastructure used to host data.
