How a Cloud is formed?

There are many misconceptions about the term cloud, usually because  there are so many definitions of it. One common misconception is that clouds are completely based on virtualization. Though virtualization usually  plays a major role in a cloud deployment, a cloud can also just  mean a shared infrastructure.  Take, for example, Google’s Gmail . This is public cloud service that does not rely much on virtualization.  Instead, massive amounts of physical hardware are in use behind the scenes.  The cloud is also not about having a dedicated network attached storage (NAS) hardware or server in residence.

But when, in IT industry, I heard this again, I was curious to know, what is it? In IT industry, each and every terminology has been borrowed from real world entities. Example: Payload, which was used in rocket science. So I assumed the same way for cloud. Cloud brings rain. So the IT cloud does!! Something like this.

How a cloud is formed? Examples of cloud in real-time? Why should I need cloud? What are SaaS, PaaS, IaaS? Why the future is movi...
