CHANGING THE WAY IT WORKS

• “Cloud” is actually a metaphor for the Internet.

• Cloud computing is a paradigm in which information is permanently stored in servers on the Internet.

In Business View:When it’s smarter to rent than to buy…..

Techie’s View:

It offers the ability to access softwares or information that can be delivered on-demand, over the internet, without the need to store it locally……

• The cloud is a large group of interconnected computers.

• It is a document-centric concept not PC centric.

IaaS- Infrastructure as a Service

• The IaaS layer extends the virtualization layer by providing the mechanisms to provision and control the virtual machines in a utility computing manner.

• The end user is able to control cost by knowing exactly how much each virtual machine instance costs per minute/hour.

• Seeks to minimize the hassle and complexity in deploying an application in the cloud.

• A programming platform is presented to the end user, typically a developer at this point, which leverages and programming language.

PaaS- Platform as a Service

SaaS- Software as a Service

• Simple way to get the application functionality you need without incurring the cost of developing that application.

• In this layer, even the platform has been abstracted away from you as an end user.
