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
Provides all the facilities necessary to support the complete process of building and delivering web applications and services, all available over the internet.
Infrastructure providers can transparently alter the platforms for their customers’ unique needs
Defined as delivery of computer infrastructure as a service
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
Amazon Elastic Compute Cloud “Amazon EC2” – web service interface that provides resizable
computing capacity in a cloud
– designed to make web-scale computing easier for developers
– reduces the time required to obtain and boot new server space from weeks to minutes
– allows developers to pay only for capacity that they actually use
