If you're unsure about what Cloud Computing is, you are probably among the 95% of people that are already using cloud services, like online banking and social networks, but don't realize it.The "cloud" is a set of different types of hardware and software that work collectively to deliver many aspects of computing to the end-user as an online service.
What is Cloud Computing?
Cloud Computing is the use of hardware and software to deliver a service over a network (typically the Internet). With cloud computing, users can access files and use applications from any device that can access the Internet.
Example of Cloud Computing :-
An example of a Cloud Computing provider is Google's Gmail. Gmail users can access files and applications hosted by Google via the internet from any device.

CLOUD COMPUTING SERVICES :-
•The first cloud computing type is infrastructure-as-a-service (IaaS)
1.IaaS is the most basic category of cloud computing servi that allows you rent IT infrastructure (servers or VM’s) from a cloud provider on a pay-as-you-go basis.
•The second cloud computing type is platform-as-a-service (PaaS)
1.Platform-as-a-service (PaaS) refers to the supply an on-demand environment for developing, testing, delivering and managing software applications.
•The third cloud computing type is software-as-a-service (SaaS)
1.Software-as-a-service (SaaS) is a method for delivering software applications over the Internet as per the demand and on a subscription basis.
How Does Cloud Computing Work?
To understand the workings of a cloud system, it is easier to divide it into two sections: the front end and the back end. They are connected to each other through a network, usually the Internet. The front end is the side of the computer user or client. The back end is ‘the cloud’ section of the system.
The front end consists of the client’s computer or computer network. Also the application essential to access the cloud computing system. It is not necessary that all cloud computing systems have the same user interface.
