Cloud Computing is a relatively new concept. While the term “cloud” had been used as a metaphor for the Internet for a long time, the term Cloud Computing in the modern sense was first publicly used by the Google’s Eric Schmidt, back in the 2006.
Cloud is a modern concept, whose intensive development takes place right now. Therefore, it suffers criticisms that are somewhat reasonable, but often exaggerated. Skepticism and financial interests are mixed. The companies that are leaders in the development of Cloud Computing technology, such as Google, have some large competitors who have no qualms about smear campaigns.
The essence of Cloud Computing is that you no longer need conventional software or hardware. The request for the hardware is minimal – you can work on a smartphone, tablet, notebook… You can also use the weakest and cheapest PC configuration on the market. At the same time you are not limited to one device: you can access your files from anywhere.
You do not have to worry about compatibility of hardware and software. Instead of bulky, burdening software, there are various SaaS, PaaS and IaaS available to you. You do not need to install anything, just sign up and you can immediately start using the selected package. Nothing can be simpler or cheaper than this.
Work is done quickly and easily. All you need is a web browser and internet access.
Necessity of internet access could be a problem, people say. What if you run out of connection? This issue will be (in the developed part of the world already is) obsolete. The possibility of losing your internet connection will be equal to the possibility of power cut. Imagine a person or company that gives up an electrical equipment, because sometimes there can be a power outage. “When the power is off I can not turn on my computer, so I better write down everything in a notebook…” It is ridiculous, but there are such examples. Take the wireless telephone for example - 20-30 years ago they were a kind of luxury. 
Now they are really cheap and widely available. But still, in some households, you can find antique telephones with dials, because – they work without electricity! Those people disregard the fact that not one phone will work when there is no electricity at the telephone exchange. Never mind that even the cheapest wireless phone has a phone book, answering machine, call ID… Old ones were better, but they no longer make such ones, what a pity!
Maybe someone will speak out against cloud computing in the same manner for 20 years. But then the whole world will be in the clouds.
