Cloud Computing

Cloud Computing: 'If you need milk, would you buy a cow?' 

You are wondering why I used tag line ‘if you need milk, would you buy a cow?' with Cloud Computing.

For that first you have to be familiar with Cloud Computing.

Ok I’ll start with a formal definition.

“Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access.”

It is a technology that uses the internet and central remote servers to maintain data and applications.

Why is it called Cloud Computing?

The name was inspired by the cloud symbol that is used to represent the Internet in flowcharts and diagrams.

A cloud can be private or public.

A public cloud sells services to anyone on the Internet. (Currently, Amazon Web Services is the largest public cloud provider.)

A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people. When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services.

Examples of Cloud Computing:-

Email on the go- Email communication now plays a central role in most of our busy lives. That’s fine if you don’t go out much but if you travel a lot, this may cause problems. Unless you carry a mobile Wi-Fi-enabled laptop with you everywhere you go or use push email on your cell phone, having an email client sitting on your computer at home means that while out and about you risk spending time outside of the communication loop. This is one area where the cloud finds it’s most frequent and useful application.

 

Working in a virtual office- Google’s online suite of office applications is probably the best known but by no means the only solution on offer. Rather than having a system and space hogging suite of applications like a word processor, a spreadsheet creator and a presentation or publishing platform sitting on your computer, you could opt to work online instead.

 

Need extra processing power?-  Most cloud environments on offer can customize the kind of service provided to exactly suit the needs of the user. If you need more processing power from time to time, a cloud-based infrastructure, being scalable, negates the need for up-front investment in client-owned resources.
