Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).The vague concept has been around for decades, and it is still a doozy.
A “Cloud” is a bag of stuff that is out there, in no particular place, but you can reach into it whenever you need it, or as they say “on demand”. You can apply this to servers, to apps – features and capabilities – to team members that are there when you need them. A cloud resource should be globally accessible, and hosted, so you don’t have to worry about how to get to it or maintain it. The idea that we can rub our laptop and summon out of the smoke a powerful genie, a huge bag of resources, is emotionally intense. That’s why “Cloud” is such a great marketing term.

What you need?

Computing devices with enough processing power to get online forget about the storage space and application.

The advantage

The cloud brings down the cost of a continuously available computing instance by 30%.

For those planning their cloud usage, you can use Amazon’s handy cloud services calculator to run your own scenarios.
