Cloud Computing?…in simple, plain English please!

Q. what is cloud computing??????

Cloud Computing is a buzzword…………The concept, quite simply, is that vast computing resources will reside in a remote location (rather than in your computer room) and we’ll connect to them and use them as needed.

With cloud computing, the s/w programs one use aren’t run from one’s personal computer, but are rather stored on servers accessed via the internet.

If a computer crashes, the s/w is still available for others to use. Same goes for the documents on create; they are stored on a collection of servers accessed via the internet.

Cloud Computing model isn’t PC-centric, its Document-Centric.

Cloud Architectures….

1. Public Cloud

2. Private Cloud

3. Hybrid Cloud

PUBLIC CLOUD

We have focused on cloud service providers whose data centers are external to the users of the service (businesses or individuals). These clouds are known as public clouds—both the infrastructure and control of these clouds is with the service provider.

PRIVATE CLOUD

A variation on this scenario is the private cloud. Here, the cloud provider is responsible only for the infrastructure and not for the control. This setup is equivalent to a section of a shared data center being partitioned for use by a specific customer. The private cloud can offer SAAS, PAAS, or IAAS services, though IAAS might appear to be a more natural fit.

A hybrid cloud involves data centers storing secure and important data on the enterprise premises and less important data to be stores at a remote location in the cloud. So it is a mixture of public and private cloud that yields the most benefit.
