Answers: What I mean is that the services like AWS Aurora are limited.
  Aurora limits replicas to 15.
  You can use larger instance sizes but there's still the replica limit.

Answers: Yes, that is correct about about Aurora. What is your question then? Or how does that relate to the scale of Netflix and Aurora?

Answers: <p>My conclusion after additional research and Preston Martin answer: <br>
  It depends. <br>
  If the workloads doesn't require more resources than the maximum supported by the service:<br>
  maximum horizonal and vertical (instance type) scale of the servers. <br>
  If it does, the data should be distributed across multiple managed database clusters. <br>
  If that doesn't meet the requirements, this solution should help: <br>
