==Economic aspects==

The cloud computing is growing rapidly. The US government decided to spend 40% of annual growth rate [[w:CAGR|CAGR]] and fixed 7 billion dollars by 2015. Huge number that should be take into consideration .<ref> {{harvnb|John Harauz, Lori M. Kaufman, Bruce Potter|p=2|id=Kaufman}}</ref>.

More and more companies have been utilizing the cloud computing to manage the massive amount of data and overcome the lack of storage capacities.

Indeed, the companies are enabled to use resources as a service to assure their computing needs without having to invest on infrastructure, so they pay for what they are going to use (Pay-as-you-go model).<ref> {{harvnb|Alireza Angabini, Nasser Yazdani, Thomas Mundt, Fatemeh Hassani|p=1|id=Angabini}}</ref>.

Every application provider has to periodically pay the cost of each server where replicas of his data are stored. The cost of a server is generally estimated by the quality of the hardware, the storage capacities, and its query processing and communication overhead .<ref> {{harvnb|Nicolas Bonvin, Thanasis G. Papaioannou, Karl Aberer|p=3|id=Bonvin}}</ref>.

Cloud computing facilitates the tasks for enterprises to scale their services under the client requests.

The pay-as-you-go model has also facilitate the tasks for the startup companies that wish to benefit from compute-intensive business. Cloud computing also offers a huge opportunity to many third-world countries that don't have enough resources, and thus enabling IT services.

Cloud computing can lower IT barriers to innovation .<ref> {{harvnb|Sean Marston, Zhi Li, Subhajyoti Bandyopadhyay, Juheng Zhang, Anand Ghalsas|p=3|id= Kaufman}}</ref>.

Although the wide utilization of cloud computing, an efficient sharing of large volumes of data in an untrusted cloud is still a challenging research topic.
