Explaining about Cloud Computing and Benefits..?

What is Cloud Computing?
                      At its simplest, cloud computing is the dynamic delivery of information technology resources and capabilities as a service over the Internet.

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. It generally incorporates infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).    

The attributes of cloud computing are:
Service-based
Scalable and elastic
Shared
Metered by use
Use of Internet technologies.

The most frequently benefits of cloud computing are:

1. It is agile, with ease and speed of deployment
2. Its cost is use-based, and will likely be reduced
3. In-house IT costs are reduced
4. Capital investment is reduced
5. The latest technology is always delivered
6. The use of standard technology is encouraged and facilitated.

                 

As applications migrate to the Internet “cloud,” as Internet access becomes ubiquitous, and as low-cost, ultra-lightweight devices (such as the new Apple iPad tablet) and inexpensive, handheld devices built on Google’s Chrome Operating System or on Google’s Android all provide access to what is increasingly the ubiquitous Internet, the number and types of tasks taking advantage of the new technology will increase by several orders of magnitude, going far beyond the comparatively modest list of things that we use computers and the Internet for today.
