title: How to deploy a Meteor app which uses Redis?
body: <p>I stumbled upon this package recently <a href="https://github.com/cult-of-coders/redis-oplog">redis-oplog</a> which seems to be a very good package. Given that I do not have any experience with Redis, I did some search and found out some say that Redis is even better than Mongo Oplog therefore I want to give this package a try with my Meteor project. However I have some questions regarding deployment before I can try it:</p>
  
  <ul>
  <li>Do I need to have separate servers dedicated for running Redis?</li>
  <li>If I can not afford to have servers for Redis, is it ok to run Redis in the same server with the Meteor app?</li>
  <li>If the my Meteor app has many instances and so does Redis (not sure if Redis could have/need many instances?), how do I make them work all together?</li>
  <li>In case I manage to use Redis for production, what changes should I make to my Mongo servers? because Mongo Oplog is no longer in use at that point</li>
  </ul>
