  +There are several possible issues that could arise when starting the stack from CloudFormation (CFN). The goal of this section
   is to provide some tips debugging the issues, and knowledge about where to find various logs. Also keep in mind
   that starting the CFN stack will typically take in the order of 15-20 minutes, mostly because of the time it takes to setup the 
   RDS cluster, so be patient...
  
positive.code: 
  Multiple instances of KAUI and the Kill Bill server are deployed in the VPC, each running on its own Ubuntu Linux server. AWS autoscaling is used to increase and decrease the number of instances of each package as needed.
  
  Access to these instances is managed by an AWS *Elastic Load Balancer (ELB)*. The ELB routes each request to the correct package and distributes the requests across the available instances. The ELB will listen on port 80 for routing traffic to the Kill Bill instances, and on port 9090 for accessing KAUI.
  
  
  The elastic load balancer will listen on port 80 for routing traffic to our Kill Bill server instances, and on port 9090 for accessing KAUI, our admin UI. Internally, both Kill Bill server instances, and KAUI server instances will listen on port 8080. These ports will be different if HTTPS is used (see below).
  
  The back end of the system is an *Aurora* database manager provided through the AWS *Relational Database System (RDS)*. Aurora is a robust database system developed by AWS, compatible with MySQL and Postgres. There are separate databases maintained for Kill Bill and KAUI.
  
  
negative.code: Note that there is also a `--account-export=<account_id>` flag to export the data associated with a specific Kill Bill `account_id`.
