What is basically cloud computing? How is it different from the traditional application hosting?

Though I have been working in the different cloud-computing engagements but yet when coming to explaining it to someone who is new or for example who is not from a IT or software back ground then it becomes a little difficult.

I have explored quite a few internet sites in quest of the same. Through this blog am trying to put it in as simple as possible.

First, it's critical to buy a blimp-defined datacenter. You just can't maintain enough airtime with traditional fixed wing or rotor aircraft. You could get by with a fixed-station balloon platform, but that reduces your availability zones.

Of course for failover, you're really going to need at least two blimps.

Google's are solar-powered. Microsoft's are expensive and enterprisey. Apple's are really well designed.

Well, maybe you don't need to worry about getting the right blimp, but if you are looking for an application environment that is:

• virtual machine only (very nearly so, or setup so you can't tell virtual from physical)
• supporting massive elasticity
• Gives the illusion of unlimited capacity
• Allows the user to grow/shrink the computing footprint on-demand, no advanced planning/contracts
• billed on a "pay as you go model"
• No fixed "I've got 1000 CPU's reserved" notion
• Only pay for what you actually use

then you are talking a "cloud computing" environment.

Traditional hosting environments, on the other hand, are based on a physical allocation of infrastructure for a contracted amount of time.  Still a great solution if you don't need the elasticity.
