Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a metered service over a network (typically the internet).
Cloud Computing provides computation, software, data access, and storage resources without requiring cloud users to know the location and other details of the computing infrastructure. At the foundation of cloud computing is the broader concept of infrastructure convergence (or Converged Infrastructure) and shared services. This type of data centre environment allows enterprises to get their applications up and running faster, with easier manageability and less maintenance, and enables IT to more rapidly adjust IT resources (such as servers, storage, and networking) to meet fluctuating and unpredictable business demand. End users access cloud based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location.
Cloud application providers strive to give the same or better service and performance as if the software programs were installed locally on end-user computers. Cloud computing, an on-demand service platform, appeals to small businesses because it provides time-and money-saving benefits. In cloud computing, different IT hardware infrastructure and software services -- such as servers, storage, CRM, accounting and so on -- are delivered to an organization's computers and devices through the internet.
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the internet, extends IT's existing capabilities.
Cloud computing can provide a lot of benefits to small businesses, but it is not a one-size-fits-all solution. Keeping track of cloud computing trends, white papers and research gives small businesses knowledge and a solid foundation to get the most value from cloud services.
