Cloud Computing: Everything you need to know
Cloud Computing is the idea of computing as a utility. It is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access.
Cloud computing removes the need to purchase physical servers by
providing these services over the web. Just need to create an account on Amazon
Web Services and set up a virtual server (EC2) and data storage (S3) all your
system via the internet. Pricing is usage-based, meaning that you pay for
exactly the amount of computing power and data storage you use.
Companies that provide cloud computing services (Amazon, Microsoft, Google) purchase server farms themselves and then make money by charging users for access via the internet for computing power and data storage on their servers. This is a significant innovation because it's exponentially cheaper and more efficient for anyone to run a web application.

Cloud Computing is actually an umbrella term for three service models:
IAAS – Infrastructure as a Service
Provision of servers or virtual servers that companies can use on a
pay-as-you-go basis. An example of this is
Amazon s Elastic Compute Cloud (EC2).
PAAS – Platform as a Service
Includes a set of lower level services such as an operating system or
computer language interpreter offered by a cloud provider on which developers
can build custom applications. A few
examples include OpenShift (Redhat), Cloud Foundry (VM Ware), Google App Engine.
SAAS – Software as a Service
Software that you access simply by navigating there in a web
browser. Facebook, Twitter, Gmail,
Google Docs are all examples of Saas. People
have been using Saas for a long time.
Why
it matters?
In a nutshell, cloud computing is accessing business data on the fly
anywhere with internet access, we already do that with our gmail or yahoo, just
like that but with business app. Imagine the dynamic nature of this feature,
only drawback "socially" is jobs, few large data center can manage a lot,
and hardware consolidation will also be the key.

And here’s a small poem on Valentine’s Day by me.
“I do not know what my life was before you came,
I do not know what my life will be without you,
I do not know how can I breathe without you,
The only thing I know for sure,
without you I do not exist.
And that thing makes us a wonderful couple...”
