Background

"Cloud computing provides users with ways to access technology applications "in the cloud", that is hosted on remote servers which can be accessed by users using the Internet."(Srinivasan) The concept of cloud computing is having everything user needs available online and being accessible without all the hardware or software. "Cloud computing service would provide a utility level infrastructure with the following operational characteristics: necessity, reliability, usability, and scalability." (Katzan). The users don't have to worry about software update, losing their information and crashing of the hard drive due because all the things needed is in the "cloud". With cloud computing, it is delivering services to the business using a combination of internal and external virtualized resources. Cloud computing focuses on the shared information over a strong network that could be accessed anywhere whenever.
