Introduction

The word "cloud computing" is most extensively apply to the applications that are third party and web-based file storage solution that permits you right of entry to programs and files on a wide range of devices without considering of one's location or position in the world (Abadi, 2009). In view of the fact that your applications and files are not stored physically in the hard drive in fact these files and applications are stored in the "cloud." A number of options are on hand for self-employed individuals, large businesses and also for persons who desire to make use of cloud computing.

National Institute of Standards and Technology defines the cloud computing as a technology which provides an access that from the remote areas to a pool of resources of computing that is shared such as servers, storage and applications, which can be altered and accessed with less interaction by the internet service provider (Armbrust et.al, 2009). In fundamental terms, this technology i.e. cloud computing allows you to execute actions, which would usually be completed on a computer similar to using a software, from whichever computer over the world using the Internet. An example of every day cloud usage is Web mail. Instead of making use of an email client which downloads the mail to the hard disk, Webmail is easy to get access from whichever computer providing you contain an Internet facility (Aymerich et.al, 2010).

The technology of Cloud computing may be separated into 2 parts, a user end and the service end. A service end is a collection of a range of Internet servers wherever applications and data are hosted. These position the “cloud” in the cloud computing. Even though the cloud might be made up of about hundreds to thousands of these servers, they are configured together to work as if these all were a single unit, pooling this collective power for computing. On the other hand, the user end may be made up of the individuals or businesses that access the applications and data stored on the servers (Hayes, 2011). A number of applications of cloud, for instance photo-sharing and Web-based mailing services, offer right of entry through a browser installed in your computer. Others employ custom software in order to access cloud. Generally, a lively connection of Internet is required to utilize Cloud services, as well as at what time your link is down, as a result is your skill to accomplish Cloud-dependent jobs (Kaliski, 2010).
