Cloud computing is the latest technology used for implementing business applications. Instead of running your apps yourself, they run on a shared data center. Cloud computing is Internet based computing where virtual shared servers provide software, infrastructure, platform, devices and other resources and hosting to customers on a pay-as-you-use basis. Cloud-based apps can be up and running in days or weeks, and they cost less. It’s not just a fad—the shift from traditional software models to the Internet has steadily gained momentum over the last 10 years. However, corporate executives might hesitate to take advantage of a cloud computing system because they can't keep their company's information under lock and key. Cloud computing customers do not own the physical infrastructure, rather they rent the usage from a third-party provider. Many enterprises look at cloud computing warily due to projected security risks. The risks of compromised security and privacy may be lower overall with cloud computing than they would be if the data were to be stored on individual machines. Cloud computing is amongst today’s hot technologies due to its ability to reduce costs associated with computing while increasing flexibility and scalability for computer processes. In this paper we will be discussing the concept of cloud computing, its characteristics, applications and future scope. The security issues and privacy concerns along with risk management have also been put forth.
