Title: What is required to run CiviCRM on Amazon RDS?

  Amazon have scalable MySQL/MariaDB offerings in [Amazon RDS for MySQL](https://aws.amazon.com/rds/mysql/) (and [Amazon RDS for MariaDB](https://aws.amazon.com/rds/mariadb/)). CiviCRM uses MySQL functionality extensively, so it would be interesting to see if the two work well together.

  We haven't tried running CiviCRM on RDS yet but we have been shifting a Drupal installation across to AWS. A few things we've noted so far that are relevant:
  
  * It helps if the RDS instance is in the same AZ as the web service
  * The various RDS instances have differing network throughput. It's poorly documented and can catch you out
  * Default settings for MySQL/MariaDB RDS from memory don't have caching enabled. You should be mindful of checking the paramater group for every RDS instance
  * Read replicas can be your friend!
