What you will learn

  • Preserve correctness under failures and retries.
  • Measure complete work and expose safe operational evidence.
  • Version release/recovery contracts with truthful validation limits.

  1. Actuator, health, and observability

    Expose deliberate operational evidence while separating endpoint exposure, authorization, health meaning, metrics dimensions, and sensitive diagnostics.

    Start learning

  2. Performance, query shape, and capacity

    Investigate a Spring Boot request through application, persistence, executor, pool, and JVM costs using comparable evidence instead of universal tuning rules.

    Start learning

  3. Outbound HTTP and resilience budgets

    Bound a Spring HTTP client, classify remote outcomes, and choose retries and fallbacks from operation semantics rather than generic exception handling.

    Start learning

  4. Packaging, deployment, and graceful shutdown

    Treat the deployable artifact, runtime, configuration, readiness, migration, and shutdown sequence as one versioned service contract.

    Start learning

  5. Reliable workflows and the outbox boundary

    Coordinate committed database state, durable operation identity, delivery retries, and consumer deduplication without claiming local events provide exactly-once remote effects.

    Start learning

  6. API evolution and release evidence

    Evolve public representations and framework versions through explicit consumer contracts, security checks, migration compatibility, and honest release evidence.
