title: How does one autoscale web dynos on Heroku?
body: <p>With Heroku, how does one <strong>AUTO</strong> scale up in terms of web dynos when it is needed? Say we get a surge of 100 concurrent users every 2-3 minutes. If our app is stuck on 5-6 web dynos. We are screwed.</p>
  
  <p>Second, I wouldn't be able to monitor traffic 24 hours to determine whether a scale up or down is required.</p>
  
  <p>So far, I've seen <a href="http://hirefireapp.com/">http://hirefireapp.com/</a> and <a href="http://www.heroscale.com/">http://www.heroscale.com/</a> 
  Any suggestions about these two?</p>
