Windex: Automation for database provisioning

This post introduces Windex, an automated system for database provisioning, which complements existing automation for detecting and resolving MySQL host issues (MPS). Windex handles the re-imaging, OS installation, and MySQL configuration of hosts, ensuring a pool of spare MySQL server instances is always available. It includes robust validation, retry logic, and failure pattern detection to prevent damage and identify root causes of provisioning failures, thereby enhancing the overall site reliability and efficiency of database infrastructure management.
