title: Server (failover) redundancy solution for Heroku app
body: <p>I have currently a node.js app deployed on a free web Dyno running on Heroku. As planning to make it production, I need to think about a redundancy and failover solution at a reasonable cost.</p>
  
  <p>As I ran "Prodiction Check" on the Heroku Dashboard, it gave me a list of things to do to make it production. One of the things is "Dyno redundancy" that I should have at least 2 web dynos running for failover. Does it mean I should upgrade my Free Dyno to Hobby or Standart 1X, and should I also need to have two dyno of the same type, e.g. two Hobby dynos or two Standard 1X dynos?</p>
  
  <p>How does Heroku handle failover from one Dyno to another one?</p>
  
  <p>Thanks!</p>
