What is Cloud Computing ? This is probably one of the most asked question right now because of emergence of Mobile based Applications with a terminology which sounds kind of pathetic to a new user – SaaS. Most importantly, if you search with the whole phrase What is Cloud Computing ? in Google Web Search, it will return you a special kind of search result. You will see the funny image of the search result return for searching with the terminology – What is Cloud Computing ?.
What is Cloud Computing ?
Cloud Computing is nothing new concept. The idea of Cloud Computing was Professor John McCarthy, who was the person behind the concept of Artificial Intelligence, Lisp and many other things, most of which proved to be effective after 50 years or so. If you have an existing idea about Grid Computing, then you will understand the concept of Cloud Computing fast, else read the hyperlinked article first.
Cloud Computing by academic classification is not a technology. The enabling technology is virtualization. Virtualization is nothing but, makes a computer to divide in to virtually separate multiple computers. That is what we use for Virtual Private Server. For easy understanding, apply the idea of virtualization with Grid Computing.
Basically all of us use minicomputer or microcomputer. The servers are also such because of microprocessor based hardware structure. If we want very elastic hardware as if the processor is like a rubber band, you can practically make it bigger by applying physical effort; this Cloud Computing plays a big role. It is normally not possible. So we have to use some extra software and suitable networking tools to give a kind of such feel.
As like you actually can not extend a rubber band to an infinite length, even if you do too much pulling and releasing, it will either become a kind of pathetic thing that lost to shrink or will break. This happens due to elastic fatigue. As everything in this World is governed by Physics (if you slap me, I will get angry and probably try to return it back – classical college campus example of Newton’s Third Law – For Every Action performed There is an equal and opposite reaction); Cloud Computing does have limit. It is not that you can increase a specific Cloud structure to have infinite GB RAM, because the physical RAM i not present.
Now as it is a matter of fact, we as user never use 2GB RAM 100% time we work. If we share the excess in a strategy, the amount becomes virtually bigger, if we can add extra computers on demand, it becomes virtually elastic. This is the basic of your Cloud Computing.
You probably got interested to know about SaaS like things, that is what we have explained in very easy language in our Cloud Computing Service Models and Deployment article.

Google is telling you via web search, what is Cloud Computing :
To get a top rank via Google Ads (that is AdWords), you will need to Pay a huge – its around $20.00 per click. You probably went thoughtful why the click costs so high ? Because Cloud Computing services needs zero infrastructure. You can buy from the original supplier and sell to a client in the way they want.
Except WikiPedia, it is very hard to find any non profit website, regardless of the content to get in the place in organic search as there are SEO who are highly paid by the commercial websites. Wikipedia copy pastes as their profit model is to ask for money to run the server. We have lot of articles on Cloud Computing, we started when ‘Cloud Computing’ was not so popular, it was of academic interest.
Cloud Computing actually is good from user’s end – pay what you need. We have shown in various free models, actually we can use the top notch infrastructure within the free quota.
