title: Google App Engine as production platform
body: <p>We are about to start working on new commercial web project and considering Google App Engine as a potential platform.</p>
  
  <p>Questions:</p>
  
  <ol>
  <li>Does Google App Engine is really
  scalable and may be considered as a
  production platform for commercial
  project?</li>
  <li>Is it more expensive (or
  cheaper) than good hosting company
  service in long run? </li>
  <li>Is it
  possible (and pretty cheap) to move
  the app from Google App Engine to
  independent server/farm (e.g. to use it
  as a private system, to exploit our
  own hardware etc.)? </li>
  <li>Is there some
  mechanism to deal with DDoS attacks?</li>
  <li>Can I make a full backup of the
  app data?</li>
  </ol>
  
  <p>Sorry for such silly questions.</p>
