Etsy uses Chef for infrastructure configuration and management. They have around 1000 nodes managed by around 30 devops engineers making regular changes. Chef Server and GitHub Enterprise are used to manage configuration code and changes. Knife-spork is used as the deployment tool to promote changes through development, staging, and production environments. Monitoring and notification tools like IRC alerts are used for change management and failure reporting.
