Introduction• "Cloud Computing", by definition, refers to the on-demand
delivery of IT resources and applications via the Internet with pay-as-you-go pricing.
• With cloud computing, you don’t need to make large upfront investments in hardware and spend a lot of time on the heavy lifting of managing that hardware
• You can provision exactly the right type and size of computing resources you need to power your newest bright idea or operate your IT department.
• Pay as you need

Example
Yahoo, Gmail, Hotmail :-
Instead of running an e-mail program on your computer, you log in to a Web e-mail account remotely. The software and storage for your account doesn't exist on your computer -- it's on the service's computer cloud.

History
• Concept evolved in 1950(IBM) called RJE (Remote Job
Entry Process).
• In 2006 Amazon provided First public cloud AWS(Amazon
Web Service).

How Does it Work?• Cloud Computing provides a simple way to access servers,
storage, databases and a broad set of application services over the Internet.
• Cloud Computing providers such as Amazon Web Services own and maintain the network-connected hardware required for these application services, while you provision and use what you need via a web application.

Advantages
• Reduce the complexity of networks.• Do not have to buy software licenses.• Customization.• Cloud providers that have specialized in a
particular area (such as e-mail) can bring advanced services that a single company might not be able to afford or develop.
• scalability, reliability, and efficiency.• Info. at cloud are not easily lost.

Saas
• SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web-based service.
– Usually billed based on usage
– Usually multi tenant environment
– Highly scalable architecture

IaaS• IaaS is the delivery of technology
infrastructure as an on demand scalable service
– Usually billed based on usage
– Usually multi tenant virtualized environment
– Can be coupled with Managed Services for OS and application support

PaaS
• PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet.
– Typically applications must be developed with a particular platform in mind
– Multi tenant environments
– Highly scalable multi tier architecture
