A review of threats and vulnerabilities to cloud computing existence

The idea that computation may be organized as a public utility, like water and electricity, was formulated in the 1960s by John McCarthy, a visionary computer scientist that championed mathematical logic in artificial intelligence. Cloud computing combines the best techniques and technologies of distributed system, parallel computing and grid computing. Is a utility computing that provides a scalable standard environment for network-centric application development, testing and deployment that distributes and allocates resources via simple user, provider model pattern of pay-per-use system. This paper aims at bringing to light some of the threats and vulnerabilities to cloud computing existence, with significance of enlighten users and providers on what is at stake on moving their business or organisation whole or partially to the cloud.
