  https://docs.killbill.io/latest/aws-singletier.html[Single Tier] or
  https://docs.killbill.io/latest/aws-multitier.html[Multitier]
  installation options. The single-tier option runs Kill Bill, Kaui, the
  MariaDB database, and the nginx load balancer on a single AWS EC2
  instance. This is suitable for quick deployment and for testing and
  development. The multi-tier option runs Kill Bill and Kaui on two or more
  separate EC2 instances, and uses an AWS RDS database manager along with
  an AWS load balancer. This is an attractive option for many production
  uses.
