Cloud-Native Observability Stack for Financial Systems: Integration of Logging, Tracing, Metrics, and Alerting Components

Abstract

Cloud-native observability has emerged as a critical capability for financial institutions seeking to maintain operational resilience while meeting stringent regulatory requirements. This article presents a structured framework encompassing logging, tracing, metrics, and alerting components, detailing the integration of key technologies within financial environments. The article demonstrates how advanced observability enables financial institutions to detect SLA violations, perform root-cause analysis, and identify anomalous financial workflows. Case studies illustrate significant improvements in incident resolution times, downtime reduction, and operational efficiency. The article also addresses the intersection of observability with security and compliance, providing actionable guidance for financial technology leaders implementing resilient, transparent systems that align with both operational excellence and regulatory mandates.
