title: Do Heroku Dynos enjoy free data transfer inside the AWS network?
body: <p>I'm considering using Heroku for a NodeJS app, and I was wondering if their Dynos enjoy the free internal data transfer inside the AWS network.</p>
  
  <p>I want to use DynamoDB, ElastiCache, RDS, SQS and a bunch of other AWS offerings - if I can connect to all of them from Heroku, which region and AZ do I need to set them up in to talk to them for free from the Heroku Dynos?</p>
