Scaling the future: How Garanti BBVA manages etcd in massive Red Hat OpenShift environments

Garanti BBVA, one of Turkey’s largest banks managing 60 Red Hat OpenShift clusters processing up to 2 billion transactions daily, addressed uncontrolled etcd database growth through multiple optimization strategies including limiting deployment revision history, eliminating unnecessary secrets, and consolidating duplicate ConfigMaps. By developing a custom tool that reduced processing time from 30 minutes to 4 minutes, the bank reclaimed 1.5 to 2 GB of storage without requiring hardware upgrades.
