Cloud computing has been envisioned as the next-generation architecture of information technology enterprises. In contrast to traditional solutions, where the IT services are under proper physical, logical and personnel controls, cloud computing moves the application software and databases to the large data centers, where some times the management of the data and services may not be fully trustworthy.
