Making Sense of Chaos: Operational Visibility in Distributed Systems
summary
A microservices retail app is deployed using Cognito, AppSync, Lambda, DynamoDB and Fargate with a Locust load generator; metrics use CloudWatch Embedded Metrics and logs feed CloudWatch Logs Insights while traces use X-Ray analytics and ServiceLens. A deliberate 7–9s sleep plus exception in the payment container produces p99 ~9s, CloudWatch anomaly detection and Slack alerts fire, ServiceLens and X‑Ray traces pinpoint the payment service 5xx and a payment gateway timeout in the logs, enabling targeted mitigation.
