The community cloud will good cost reducing benefit to the community clouds organizations.

Hybrid clouds

A hybrid is a cloud computing in which an organization provides and manages some services in house and some service are providing externally on the place of the clients. In hybrid clouding a company may use the public cloud service but those companies that company continue to maintain their in house data storage for their operation. The hybrid cloud may be very cost effective for the clients and public clouding may save the company's personal data from to expose from third parties.

Hybrid cloud is mixture of one private cloud and at least one public cloud. Hybrid cloud is offering service two ways either vendor has private cloud and forms a partnership with a public cloud provider or public cloud provider forms a partnership with a vendor that provides private cloud platforms.

Private cloud

private cloud will provide the infrastructure only one organizations or company, weather that cloud managed by internally or by the third parties. Private cloud provider company will help and manage only one company data and their business operations applications.

How cloud computing works

suppose when any company hired a new employee for their organization, that employee need a computer for their working operation in the companies. Company provides the computer to new employee but that new hired employee cannot start his/her work on the computer immediately. The computer which he/she gets needs some software to be installed in his/her computer for work as per the company business model. For installing the new software in that computer required licenses for work operation.

Now with the help cloud computing, there is no need to install the new software's in the computer. Now computer executive of the company has to install only one cloud application alone software in the computer. That cloud application when the employee login through network on it, He/she will get all the required software with license from the cloud application. Now the company has not required buy additional software license for that software. The remote machine which is owned by another company would run all the software which is required to the employee for their need for work operation. This is called cloud computing.

We all persons have used somewhat cloud computing service. We are using the e-mail account from the web based e-mail service like yahoo mail, Google mail and more e-mail service provider company.
