One of the world developments of information technology is to the efficient use of computer hardware. The way to hardware efficiency is to use cloud computing or cloud virtualization. There is a difference between cloud computing and cloud virtualization. Cloud computing is a form of computing Internet-based that offers resources such as storage and information processing capabilities. While cloud virtualization makes resource simulation and enables the computer hardware can provide multiple services as well.

Service virtualization and cloud computing over balancing the needs and resource provision, allowing the hardware to achieve their full potential. The cloud virtualization is users do not need to buy new hardware to try a particular environment, while the benefits of cloud computing by the use of a company is likely to save because the company does not need to buy hardware to perform the operational, but only by subscribing to cloud computing services.
