Cloud Computing: Simplified!

Basics of the Basic!

I’m sure y’all must have heard or read about Cloud Computing, the big buzz surrounding it and why it is a hot concept! Ever wondered ‘Why the word- CLOUD?!’ I’ll take a pause while you ponder!

Well, ‘Cloud’ is just a simple jargon used to identify the huge abstraction about various components that it engulfs. It is a generalized term which is put up for the complex infrastructure that it contains. Still pondering?! Let me simplify further. You must be knowing that there exists data, content stored in an IT environment, the storage and security systems enacted for it, the hardware and software used, various applications catering to different functions to be performed, the databases, networking components, compute resources, the web services and finally the PCs, tablets and smart-phones that we play with to use the aforementioned components. In short everything that can be included in an IT environment. This ‘Everything’ is ‘Cloud’!

This everything is yours but not with you! Perplexed again? You must be definitely using some or all of the web services like emails, banking services, shopping portals, e-learning resources, job search portals, social networking sites, photo sharing sites, music storage sites etc. You amply use them through your lappys, tablets or phones. Ever wondered that these services are accessible through internet and none reside as a software/ application on your device? Probably simply residing as an application/ program through which you can just access these services and their huge data over the web. This is a generalized and common usage scenario of Cloud facility! When we illustrate network diagrams, you must have seen ‘internet/web’ is depicted by a cloud pictogram. That’s the basic origin of the term ‘Cloud’.

As a symbol for the Internet, ‘the cloud’ is a familiar cliché, but when combined with ‘computing’, the meaning gets superior and fuzzier. Cloud is a service (services) and Computing is the way in which this service is reaching to us. The services or facilities that I mentioned before are given to us through a massive collection of compute and network resources. They are actually hosted elsewhere but we can use it on our desktops or palmtops. It is a utility and we just use it! We don’t really do any management or maintenance or scaling-up. It is done by the vendors of those technologies and they might just charge us for using them. That’s what Cloud Computing is, only generally though. Technically, it is an extremely gigantic model.

On the whole, Cloud Computing is about:

  • The service models of Cloud / Types of Cloud Services viz. IAAS, SAAS, PAAS
  • The deployment models of Cloud/ Types of Clouds viz. Public, Private, Hybrid Cloud
  • Usage and concerns of Cloud Computing
  • Lots and lots more

Check out the different definitions of Cloud Computing terminologies explained in a lucid and interesting manner. If big IT jargons perplex you, go through the simple information that’s put-up on the below web resource. The pictorial illustrations are entertaining. It’s sort of a beginner’s guide to Cloud vocabulary! :)

Ten cloud computing definitions you need to know

Curious to know more?! The below web resource gives some interesting information about the ways in which Cloud Computing is put into actual practice.

How Cloud Computing Works

Now that you have read this Hub, I’m sure you are inquisitive enough to know further. I’ve tried my best to simplify the concepts and cater to any newbie or technically disoriented person’s curiosities. Since Cloud Computing is an extremely vast concept, I’m trying to come up with a simpler version involving the technicalities by myself. I’ll write more Hubs on that regard as I believe in keeping each Hub short and simple. Hoping to give you valuable knowledge! J
