Cloud computing is basically
where a company uses someone else’s computing services (usually over the
internet) instead of having to run that software on their own computers. It makes
sense but it doesn’t make full understanding, right?
Now read this example, I hope
this helps. Cloud Computing is similar to electricity boards, that supply
electricity to your homes. To give you an example, you all consume electricity
at home. You turn on your fans, bulbs, TV sets, Washing Machines, and all this
happens at a mere click of a button. You press the buttons and electricity runs
through your home appliances. You do not have to worry about who supplies this
electricity to your home. Neither do you have to worry about how it is
supplied, how it is maintained? The electricity provider takes care of all
these issues. What you do, at the end of the month you get a bill saying that
these are units of electricity consumed and this is the amount you need to pay.
Well, Cloud Computing is like
your electricity board. But instead, they provide cloud computing or application
hosting and quite a few other services in a similar manner. Let’s take a look at a
bookish definition before moving any further.
“Cloud Computing enables
on-demand services like compute, storage, networking, etc. which can be
accessed through the internet and the user is not required to manage these
resources.”
So, to simplify it further, Cloud
Computing addresses all the concerns that you discussed in Why a bit of Cloud
Computing. It provides:
- Pay as you go, payment model
- Is accessible from most part of the world
- Can be accessed through the internet
- The vendor takes care of managing and monitoring these services
- The resources provided can scale up and down depending upon the requirement
What this means is you can more
or less rent the services mentioned and release them whenever you can
want. You will be charged only for the time duration you used these resources.
With instant scalability and support, you can focus on your business problems
more and less on the configuration part. Hope this explains the basic idea of it.
