Information and Communication Technology: Cloud Computing

First of all, enterprise ICT can regard cost reduction as a big advantage of CC. Companies rely on ICT's classic model at the cost of electricity, hardware, software, maintenance, IT staff, etc, but CC providers can use ICT systems and applications as services at low cost, in an acceptable time, We can offer. , Few people and low power consumption. According to the report of Gelenbe, di Girolamo, Giuliani, de, Quan, Pentikousis (2009), the data center server occupies 50% or more of the total energy cost, and more than 20% is occupied by electricity and cooling. Equipment, therefore cost reduction

Gilbert (2010, p.1) noted that "Cloud computing has been recognized as one of the most important developments in information technology in the past 60 years." To reduce costs, the organization responds more closely to the demands of the market to reduce costs, we introduced cloud service solutions and provide better customer service to share information more easily and quickly. Cloud computing has been achieved with technology drivers such as reduced communication costs, the Internet and its growth rate, increased processing power and footprint for data processing, Internet security, virtualization, etc.

The demand for information in our society is growing at an unprecedented speed. A still unmet need for communication, computing, and downloads is driving this demand. Needless to say 300 hours of video to be loaded on YouTube every minute, with the advent of new technologies such as cloud computing and the Internet of Things, the tendency for access to information to become increasingly fast is showing signs of a slowdown not. The reason why information can be transferred at high speed is mainly centralized data center because computing devices called servers are lined up.

Cloud computing has become a ubiquitous term and has been widely debated in the world of information technology (IT) in the world. Cloud computing dramatically changed the way of communication and collaboration between organization and individual. The concept of cloud computing guarantees cost-effective conversion of the principles of utility computing, allowing users and providers to easily access resources with self-service and "pay anytime and anywhere". As a result, cloud computing reduces the costs associated with system administration and helps improve resource utilization and accounting. Since recent years, cloud computing has had many positive impacts on the IT ecosystem. As a result, a new market and a newly widely dispersed user base were born (European Commission, 2012).
