Healthy Pods, Broken Transactions: What Kubernetes Doesn’t Catch in Banking Systems
The article discusses the limitations of Kubernetes in monitoring banking systems, particularly in handling payment authorizations. It highlights how standard observability fails to catch issues like thread exhaustion and service slowdowns. The author provides solutions to improve system resilience and performance through custom health indicators and proper timeout configurations.
- ▪Kubernetes observability is unable to detect silent failures in payment authorizations.
- ▪A slow Fraud Service can lead to widespread card authorization failures without any crashes.
- ▪Custom health indicators and appropriate timeout settings are essential for maintaining service performance.
