Q

What is Cloud Computing?

A

It is a combination of hardware and software accessed over the Internet from a different site and with minimal effort from the end-users.
It refers to how everything, from computing power to computing infrastructure, applications, business processes, and personal collaboration, can be delivered as a service wherever and whenever needed.
It is a group of interconnected network servers or PCs that may be private or public. The data and the application served by the cloud are accessible to a group of users through the network.
It is a model for enabling convenient, on-demand network access to a shared pool of configurable resources (e.g. network, servers, storage, applications, and services that can be accessed with interaction from users and service providers .
