  "Description" : "AWS CloudFormation Sample Template Insoshi_Single_Instance_With_RDS: Insoshi is an open source social networking platform in Ruby on Rails. This template creates an Insoshi stack using a single EC2 instance with an Amazon RDS database instance for storage. It demonstrates using the AWS CloudFormation bootstrap scripts to install the packages and files necessary to deploy the Insoshi, Rails, MySQL and all dependent packages at instance launch time. **WARNING** This template creates an Amazon EC2 instance, an Amazon RDS database instance and other AWS resources. You will be billed for the AWS resources used if you create a stack from this template.",
