What is Cloud Computing? Massive computing resources, deployed among virtual datacenters, dynamically allocated to specific users and tasks and accessed as a service via an user interface (UI), such as a web browser.
The physical cloud resources may reside in a number of locations, the details of which are not typically known to the service’s users.
Cloud resources are offered as a service on an as needed basis. The cloud itself typically consists of large numbers of commodity-grade servers, harnessed to deliver highly scalable and reliable on-demand services.

Cloud TechnologiesTechnology Key Feature What’s Missing
Grid Computing Job scheduling across many machines
Difficult to administer; Lacks broad applicability of cloud computing
Virtualization Virtual machines decouple OS from hardware
Fail to fundamentally solve scale and reliability
IaaS Infrastructure-as-a-Service
Computational infrastructure available for rent
Lacks security , vertical solutions,
SaaS Software-as-a-Service
Application availability through the cloud
SaaS is an application on the cloud, not a cloud by itself
Utility Computing Packaged computing, application, and storage sold as a service
Describes a business model, not a technology or architecture
