The term Cloud Computing is relatively new, and some say it is no different than “Utility Computing,” the idea that the internet is the electric company. The image of a cloud comes from engineers and technicians who use a fluffy cumulus cloud in wiring diagrams to designate a network built and maintained outside of an organization. The faster internet connections have become – 10mbps, 20 mbps, 40 mbps, the more applications and storage have moved to the Cloud and out of internal servers and PCs. In fact, all processing power, applications and storage a communications professional might need today are available already through Cloud Computing.
Cloud Computing requires high-speed broadband service and enormous data storage, but current predictions are that nothing will stop the internet from reaching petabyte size and speed. That is a thousand trillion bytes of storage, an unimaginable size, and equally astonishing speed. This means millions of people can download multi-billion-byte, high- definition, feature-length movies at the same time without slowing down or straining the internet. There are serious capacity and economic issues to achieving this scale, but internet service providers are moving to solve them. Some countries have already achieved extraordinary speed and volume such as Korea, Japan and Australia.
Figure, adapted from Voas and Zhang (2009), shows six phases of computing paradigms, from dummy terminals/mainframes, to PCs, networking computing, to grid and cloud computing.

Figure, adapted from Voas and Zhang (2009), shows six phases of computing paradigms, from dummy terminals/mainframes, to PCs, networking computing, to grid and cloud computing.
In phase 1, many users shared powerful mainframes using dummy terminals.
In phase 2, stand-alone PCs became powerful enough to meet the majority of users’ needs.
In phase 3, PCs, laptops, and servers were connected together through local networks to share resources and increase performance.
In phase 4, local networks were connected to other local networks forming a global network such as the Internet to utilize remote applications and resources.
In phase 5, grid computing provided shared computing power and storage through a distributed computing.
