Well-Architected architecture study
Observability and Incident Response Platform
An operations design that connects metrics, traces, logs, alerts, runbooks, and post-incident review into one response workflow.

Problem
Dashboards are useful, but operations improve when signals trigger clear ownership, severity, remediation steps, and follow-up work.
Design
- Applications publish structured logs, metrics, traces, and business health indicators.
- CloudWatch alarms use service-level thresholds rather than noisy single-resource checks.
- X-Ray traces help identify latency and dependency failures.
- SNS and Incident Manager route alerts by severity and ownership.
- SSM Automation runbooks perform safe diagnostic or remediation steps.
- Post-incident review turns repeated failures into backlog items.
Well-Architected lens
- Operational excellence: runbooks, alarms, ownership, and continuous improvement.
- Reliability: faster detection and recovery from degraded dependencies.
- Security: least-privilege automation roles and audit history for remediation actions.
- Cost optimization: log retention classes, sampling, and alert noise reduction.
Why it is not live here
The portfolio already has simple CloudWatch logging. A full incident platform only makes sense with multiple services, on-call ownership, and real operational load.
