Cloud Computing Models

[nejin]

Public cloud
Public cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who bills on a fine-grained utility computing basis.

Community cloud
A community cloud may be established where several organizations have similar requirements and seek to share infrastructure so as to realize some of the benefits of cloud computing. With the costs spread over fewer users than a public cloud this option is more expensive but may offer a higher level of privacy, security and/or policy compliance.

Hybrid cloud
A hybrid cloud environment consisting of multiple internal and/or external providers "will be typical for most enterprises". By integrating multiple cloud services users may be able to ease the transition to public cloud services while avoiding issues such as PCI compliance.
Another perspective on deploying a web application in the cloud is using Hybrid Web Hosting, where the hosting infrastructure is a mix between Cloud Hosting for the web server, and Managed dedicated server for the database server.

Private cloud
The concept of a Private Computer Utility was first described by Douglas Parkhill in his 1966 book "The Challenge of the Computer Utility". The idea was based upon direct comparison with other industries and the extensive use of hybrid supply models to balance and mitigate risks.

Cloud computing give one enormous infrastructure without having to implement and administer it directly. And that is why it is creating such big noises in the industry.

How does it differ from VPS Hosting ? Even VPSes are also similar right ? Cutting an hardware node into pieces ?
