What is Cloud Computing?

INDEX

It is the idea of relying on Web-based application and storing data in the “CLOUD’’ of the internet i.e., information is permanently stored in servers on the Internet.

What is CLOUD COMPUTING?

“Cloud” is simply a metaphor for the internet

Users do not have or need knowledge, control, ownership in the computer infrastructure

Users simply rent or access the software, paying only for what they use

Fully outsourced service so businesses do not have to purchase servers, software or equipment.

Infrastructure providers can dynamically allocate resources for service providers

Service providers offer this service to end users

Allows cost savings for the service providers, since they do not need to operate their own datacenter
