Configures AWS cost anomaly detection and budget services for monitoring
Here's what using the module will look like
module "example" {
source = "rhythmictech/rhythmic-cost-monitor/aws"
datadog_api_key_secret_arn = ""
}Rhythmic is an AWS Managed Services Provider. We rely heavily on automation to deliver our services, ingesting configuration, event and state information from AWS via listeners (e.g., EventBridge and SNS), services (e.g., Anomaly Detection), and APIs via custom scripts (e.g., Trusted Advisor).
We open source the vast majority of the resources we use to deliver our managed services because transparency is one of our principles.

This workflow has a few prerequisites which are installed through the ./bin/install-x.sh scripts and are linked below. The install script will also work on your local machine.
We use tfenv to manage terraform versions, so the version is defined in the versions.tf and tfenv installs the latest compliant version.
pre-commit is like a package manager for scripts that integrate with git hooks. We use them to run the rest of the tools before apply.
terraform-docs creates the beautiful docs (above), tfsec scans for security no-nos, tflint scans for best practices.
