Distributed Tracing with OpenTelemetry: Follow Every Request Across Your Services

Learn to instrument your services with OpenTelemetry and see each request's full journey: auto-instrumentation in Python and Node.js, custom spans with useful attributes, W3C context propagation (including manual propagation across queues), sampling strategies, and Collector configuration. Covers the cardinality and propagation mistakes that ruin traces in production. Expanded with span kinds, events and links, semantic conventions, correlating traces with logs and metrics (exemplars and span metrics), baggage, the Collector in production (agent + gateway and scaled tail sampling), sensitive-data redaction with OTTL, instrumentation testing, overhead control, systematic debugging of broken traces, gRPC and streaming, the OTel Operator on Kubernetes, burn-rate SLOs and a complete hands-on investigation case study.

Circuit Breakers: How to Prevent Cascading Failures in Distributed Systems

Learn to implement the circuit breaker pattern so a failing dependency never drags down your whole system: the three states (closed, open, half-open), sliding failure windows, limited probes to avoid thundering herds, robust fallbacks, and how to combine it with timeouts, retries, and bulkheads. Includes distributed state in Redis, observability with Prometheus, pytest testing, circuit breaking in Envoy/Istio, a full case study, and production-ready code in Python and TypeScript.
