Topic 1: Cloud Computing.

Cloud Computing: 
Definition: "Cloud computing is a model for enabling convenient, on-demand network
access to a shared pool of configurable computing resources (e.g., networks,
servers, storage, applications, and services) that can be rapidly provisioned
and released with minimal management effort or service provider interaction." as per NIST.

It means all the Software, Infrastructure, Data Storage and platform are on remote servers. The user access these things as service on his web browser. User pays for this service he uses.

Ex: MS OFFICE is very costly software product of Microsoft. Even you require only MS WORD, you have to pay for the entire software. So you can save you budget by using MS Word as a service.
These are kinds of Cloud Computing software Applications. The common tag lines to Cloud Computing is "NO SOFTWARE" or "PAY AS MUCH AS U USE".

Now coming to various services we are taking about, there are many cloud services. Please refer to Wikipedia for entire information. Two important services are

SaaS ~ Software as service. Ex: Salesforce.com. There nothing to develop here. Developed Apps are directly used as service.

PaaS ~ Platform as service. Ex: Force.com. Here developers come into picture. They develop there custom apps as per the requirement on vendor platform (Force.com).

Salesforce.com is a CRM application. Force.com is a platform where you develop apps.
