# Cloud Formation
2+
This directory just has a few mess-around templates for testing AWS Cloud Formation during POC, although this was not
3+
at all a focus during the POC.
4+
5+
Useful, although incomplete, resource:
6+
- http://callistaenterprise.se/blogg/teknik/2013/01/17/set-up-a-tomcat-server-on-aws-using-cloudformation-2/
7+
8+
In testing setting up a basic EC2 instance, this took just short of two minutes - nice.
