Cloud Computing.

 

 

 

What is Cloud?

Cloud computing is Internet-based computing, where shared resources, software and information are provided to computers and other services on demand.

 

The "Cloud" market today has different as-a-Service (aaS) offerings:

 

 

Iaas - Infrastructure-as-a-Service:

-- IaaS Comproses the provision fo Virtual Hardware and Basis Infrastructure. Amazon's EC2 service and cloud-enabling technologies and services from HP are the best examples for IaaS.

 

Paas - Platform-as-a-Service:

-- PaaS offers software providers a development platform with a direct connection to the cloud. For an example, providers like Microsoft deliver technical frameworks and enable customers to develop software that hooks up with other technology platforms using standardized interfaces.

 

SaaS - Software-as-a-Service:

-- With SaaS, the software provider ships its product to customers using the Internet. Users don’t need their own hardware. Instead, they have a subscription for the application and run it using their Web browser. An example of SaaS in the business environment is the SAP Business ByDesign solution, which will finally become widely available in 2010. In the consumer segment, Web mail and photo album services are the most widely used SaaS applications.
