title: Normal web app Vs cloud based web app
body: <p>We get to hear cloud based computing a lot these days.</p>
  
  <p>I just wanted to understand the basic difference between a web app and one which uses cloud based (SAAS model as they also say)
  It is said that the cloud means hosting the application at a common place for all the users, instead of one per user. But I find it confusing since a normal web app also does the same.
  So what is the difference ?</p>
