01 — Monitoring Patterns

Patterns

A book-shaped table of contents for reusable engineering patterns spanning object-oriented design, enterprise architecture, distributed systems, messaging, APIs, cloud infrastructure, observability, security, concurrency, AI/agentic systems, and organizational design — grounded in production experience at scale.

04 — Alerting Patterns

Multi-window Burn Rate alerts, SLO Alerts, Composite Alerts, and Noise Reduction — the alerting design that pages on user-facing pain instead of every internal wobble.

02 — Logging Patterns

Structured Logging, Correlation IDs, Log Sampling, and Log Aggregation — how logs stay searchable and affordable at scale instead of becoming a second, worse metrics system.

03 — Tracing Patterns

Distributed Tracing, Context Propagation, and Tail vs. Head Sampling — how a single request's path across services becomes reconstructable instead of a pile of disconnected spans.

01 — Sidecar

Co-locate a helper container with the application container to handle cross-cutting concerns — TLS, observability, auth, retries — without modifying application code.
