Cloud computing is a general term for the delivery of computing services such as servers, storage, databases etc over the internet.
Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage.
Google hosts a cloud that consists of both smallish PCs and larger servers. Google’s cloud is a private one (that is, Google owns it) that is publicly accessible by Google’s users.
Feature of Cloud Computing-
Cloud computing is-
1. Cloud Computing Is User-Centric:
Once you as a user are connected to the cloud, whatever is stored there, be it documents, messages, images, applications, whatever becomes yours. In addition, you can also share it with others.
2. Cloud Computing Is Task-Centric:
Instead of focusing on the application and what it can do, the focus is on what you need done and how the application can do it for you.
3. Cloud Computing Is Powerful:
Connecting hundreds or thousands of computers together in a cloud creates a wealth of computing power that is impossible with a single desktop PC.
4. Cloud Computing Is Accessible:
Because data is stored in the cloud, users can instantly retrieve more information from multiple repositories. You’re not limited to a single source of data as you are with a desktop PC.
5. Cloud Computing Is Intelligent:
With all the various data stored on the computers in a cloud, data mining and analysis are necessary to access that information in an intelligent manner.
6. Cloud Computing Is Programmable:
Many of the tasks necessary with cloud computing must be automated.
For example, to protect the integrity of the data, information stored on a single computer in the cloud must be replicated on other computers in the cloud. If that one computer goes offline, the cloud’s programming automatically redistributes that computer’s data to a new computer in the cloud.
