Cloud Computing

Introduction

Cloud computing is utility computing or grid computing, or software-as-service or managed service. Each and every person is talking about this new concept 'cloud computing.' Cloud computing is overhyped because it is a very old concept. This concept was introduced in the 1960s; however, it is used in a different way today. Cloud computing refers to the usage of software with the help of a browser. Google docs is a very good example of cloud computing. Cloud computing is a concept that is used in IT outsourcing. Outsourcing is also a new concept which uses cloud computing (Sensible, 2008). Cloud Computing is the culture of outsourcing some part of company's technology to a common 3rd party setting.

The terminology is new but the concept is not fresh. In the past, same contributions were known as Application server provider. Internet is frequently known as the cloud & the terminology Cloud Computing take place from this correlation. Cloud Computing is defined as the dynamic and active provisioning of Information Technology potentials like software, hardware and services from 3rd parties on a network. McKinsey states that clouds are hardware supported services offering network plus, compute, storage ability where hardware administration is extremely thoughtful from the consumer; buyers obtain infra-structures and communications costs as variable operating expenditures & infrastructure ability is extremely expandable.

Cloud Computing

Although the basic idea of Cloud Computing is not really new, considering the relatively young age of the new term Cloud Computing. The concept of cloud computing significantly changed the traditional approach to the delivery, management and application integration. Compared with the traditional approach, cloud computing can manage larger infrastructures serving multiple user groups within a single cloud, and the mean total dependence on the provider's cloud services. Cloud Computing is becoming the center of attention: large and small companies are gathering around the model of cloud computing business applications. Cloud Computing platforms are the antidote to many of the problems associated IT to the traditional model of installed software (Schneier, 2009). With no software or hardware to buy, install, maintain or upgrade, the popularity of on-demand model is augmented by IT organizations to which they are asked, more often, do more with less in times of crisis.

Cloud computing is a model of computing whereby individuals or firms obtain, for a fee, computing power and software applications via the Internet. Essentially it is a rental of computer hardware and software for the purpose of running a business. In many ways it reduces the amount and type of resources one must obtain in order to successfully and cost effectively run a business. This is a very popular and growing strategy used by companies that have significant computing power needs—such as video sharing and storage as well as ecommerce. Cloud computing is one of the fastest-growing forms of computing, and according to Gartner Research, was approximately a $56 billion industry in 2009 and is expected to grow to $150 billion by 2013.
