title: mongodb vertical scaling on EC2
body: <p>So I got my replica set up and running on an m3.large instance.</p>
  
  <p>If I would like to <strong>vertically scale</strong> the replica set, will it be as easy as resizing the machine to a m3.2xlarge for example?</p>
  
  <p>Should I change some mongodb configuration in order to let it use more memory or cpu?</p>
