Application Insights

Capture dependency telemetry for SQL, Redis, and HTTP calls

Explains dependency duration, error rate, timeout rate, query tagging, Redis latency, HTTP downstream calls, and endpoint correlation.

Choose hotfix, rollback, or feature disablement during an App Service incident

Reason through mitigation choices during a live App Service production incident.

Choose rollback, roll-forward, or kill switch during incidents

Compares rollback, roll-forward, feature kill switches, scaling, and degraded mode as incident mitigations.

Choose rolling, blue-green, or canary deployment

Chooses a deployment strategy from capacity, compatibility, risk, observability, and rollback needs, then defines progressive promotion and abort signals.

Compare OpenTelemetry and Application Insights instrumentation

Compares vendor-neutral OpenTelemetry concepts with Application Insights usage for .NET production services.

Control trace sampling, metric cardinality, and observability cost

Explains sampling, high-cardinality labels, retention, cost, and keeping enough signal for incident diagnosis.

Observability & Production Incidents

Logs, metrics, traces, alerts, triage, mitigation, and post-incident learning.

A practical production-ownership track covering observability foundations, correlation IDs, structured logs, dependency telemetry, OpenTelemetry, health checks, sampling, incident triage, slow API diagnosis, post-release failures, downstream dependency incidents, missing logs, queue backlogs, auth failures, SLO alerts, dashboards, release correlation, mitigation choices, post-incident reviews, runbooks, and capacity/backpressure signals.

Cloud & DevOps

CI/CD, source control, deployment, release management, and production operations.

A focused DevOps track covering Git workflow, CI/CD pipelines, containers, infrastructure as code, deployment safety, progressive delivery, supply-chain security, disaster recovery, release management, observability, and operational ownership.
