## What it is
A Terraform module that provisions auto-scaling, self-hosted GitHub Actions runners on AWS spot instances, using Lambda functions to orchestrate runner scale-up and scale-down. It supports ephemeral runners, scale-to-zero cost savings, Linux and Windows runners, and multiple runner configurations per deployment.

## Use cases
- self-host github actions runners on aws
- autoscale ci runners based on github events
- run github actions workflows on spot instances to cut costs
- scale runners down to zero when idle
- create ephemeral runners for security
- deploy multiple runner configurations for an organization
- use custom amis and instance types for ci workloads

## When to choose
- you want self-hosted GitHub Actions runners on AWS with automatic scaling
- you need cost-optimized CI via spot instances and scale-to-zero
- you want ephemeral, on-demand runners for better security
- you need Linux (x64/arm64) or Windows runners with custom AMIs
- you use GitHub Enterprise or data-residency runners

## When to avoid
- you prefer Kubernetes-based runners like ARC
- you don't use AWS or Terraform
- you only need GitHub-hosted runners
- you want a fully managed solution without infrastructure maintenance
