Introduction
What is Cloud Computing?
Online file storage
Social Networking Sites
Webmails
online business applications
History
Even though the cloud has only just recently hit its stride and began to expand the field for data mining and collecting, the concept of computing via a universal database is decades old.

Cloud Computing Architecture
Cloud Computer Applications
The Application of Cloud Computing are limitless.With the right middleware, a cloud computing system could execute all the programs a normal computer could run. Potentially, everything from generic word processing software to customized computer programs designed for a specific company could work on a cloud computing system.
Cloud Computing Concerns
front end
back end
middleware
End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location
Why would anyone want to rely on another computer system to run programs and store data?
Access

Costs

Achieve Goals

It Support
Access
-
Clients would be able to access their
applications
and
data
from anywhere at any time.
-
They could access the cloud computing system using any computer
linked
to the Internet. Data wouldn't be confined to a hard drive on one user's computer or even a corporation's internal network.
Costs
-It could bring
hardware costs
down. Cloud computing systems would reduce the need for advanced hardware on the client side.
-You wouldn't need to buy the fastest computer with the most memory, because the cloud system would take care of those needs for you. Instead, you could buy an inexpensive computer terminal.
Achieve Goals
Corporations that rely on computers have to make sure they have the right software in place to achieve goals. Cloud computing systems give these organizations company-wideaccess to computer applications. The companies don't have to buy a set of software or software licenses for every employee. Instead, the company could pay a metered fee to a cloud computing company.
Advantages & Disadvantages

Cloud computing is the new buzz word of 2013.
And even if you think you know nothing about this concept, chances are you are already using an application ‘in the cloud’.
Will 2013 finally be the year executives stop worrying about cloud security and actually start looking at their bills from cloud service providers?
This has been a curious year for cloud computing. The technology has moved into mainstream consciousness, but many vendors remain frustrated with the pace of enterprise adoption.
While widespread agreement about the importance of cloud computing is present, many vendors see enterprises pursuing internal cloud implementation projects with a slow pace. As you can imagine, vendors are impatient with this pace—but not as frustrated as early-stage investors in those vendors.
Notwithstanding, I expect 2013 to be an inflection point for cloud computing, although not in the way many IT organizations or vendors do. You can expect that cloud computing trends of 2012 will become more vivid in 2013 and will prove disconcerting to incumbents, no matter which side of the vendor/buyer table they sit on. Cloud computing will prove more disruptive to the established order of things
