This document describes the procedures for setting up Kill Bill under AWS using the single-tier option. This option has limited capabilities but is very easy to setup. It uses a minimum of resources and may be suitable for very simple use cases. Everything you need for this option is bundled in the Kill Bill Amazon Machine Image (AMI) and will be launched on a single virtual Linux system, which AWS calls an EC2 instance.
The components of this system include Kill Bill, Kaui, a database manager (DBM), and a load balancer. The EC2 instance runs Ubuntu Linux. The DBM is an instance of MariaDB, an open source version of MySQL. The load balancer is the open source package Nginx. This package serves as a front end or reverse proxy, distributing the incoming traffic to either Kill Bill or Kaui based on the incoming port.
The organization of the single-tier system looks like this:
In this configuration, Kill Bill and Kaui are deployed within the
tomcat application server. Requests are handled by
nginx. Requests received on port 443 are delivered to Kaui, and those received on port 8443 are delivered to Kill Bill. Both Kill Bill and Kaui communicate as needed with the
The setup procedure includes nine steps:
