Using CloudWatch to trigger Lambda execution at a given intervals, the Lambda app(s) then trigger SNS notifications at second-level granularity. The SNS topic can then be used to spawn Lambda functions to do your bidding.

Deployment

1. Configure the shadowconf.hcl file in the project root as needed.
2. Execute shadow fax *.tf.tpl.
3. Run terraform init, plan, and apply in the project root to create the SNS topic.
4. Add the topic_arn to the shadowconf.hcl file in the project root.
5. Execute shadow fax terraform.tpl to generate the terraform directory.
6. Change into the terraform directory and execute terraform init, plan, and apply.
