Cloud
computing is a term in which information is permanently stored in
servers on the Internet and temporarily stored on the user or client
computer such as desktop, tablet computers, notebooks, wall computers,
handhelds, sensors, monitors and others. Cloud Computing is the combined use of computer technology (computing) and the development of Internet-based (cloud). The cloud is metefora from the internet, which is often depicted as clouds in computer network diagrams.
The initial idea of cloud computing comes from a computing expert from MIT named John McCarthy in the 1960s. He stated that one day computing will be a public infrastructure such as electricity and telephones. Then in 1995, Larry Ellison led to the idea "Network Computing" as a campaign to sue Microsoft when it dominates desktop computing.
Larry Ellison stated user does not actually need software such as operating systems and other software running on their desktop pc. Later this idea can be realized in the early 21st century when it was discovered various techniques in software development and Internet capacity.
Nowadays more and more rapid development of the digital world. In 2010, all data stored in the world is 1.2 Zettabyte and will be 30 years 2020.Dengan Zettabyte on such developments required a special technique that is able megatasi computational problems.
The advantages of cloud computing include ease of access, flexible, large storage, saving cost and energy efficient. Cloud computing also has shortcomings such as the Internet connection should be sufficient, undoubtedly data security and quality issues server.
Looking at developments in the computing world is very rapid, cloud computing is a solution of computational problems to be faced. With so many advantages of cloud computing is that cloud computing will also be growing. Shortage faced will be minimized with a variety of infrastructure improvements and techniques used.
