Setup

The code for this broker is not available on GitHub because it is organization-specific. It must be implemented by each organization. Liberty Mutual used an interface provided by the AWS Lambda Java core library (aws-lambda-java-core) to create a Lambda function handler for the CFT Push Variable Broker.
