## Budget Safety Switch
This is a CloudFormation template that deploys a Lambda function which, when triggered, looks through every region and stops (or, in the case of instance-backed instances, terminates) EC2 instances that don't have a KeepRunning tag set.

## Budget Safety Switch (SAM Template)
A repackaged version of the above template using the Serverless Application Model (SAM) framework.  This version also allows you to define a specific tag key/value combination for the instances you want to keep.
