Health, Monitoring & Observability
A service that's running isn't the same as a service that's actually able to do its job. This module builds the health signal that Module 20's Kubernetes probes will later consume.
Learning objectives
- Beginner: Explain the difference between a service that's "running" and one that's actually able to do its job.
- Intermediate: Wire up Spring Boot Actuator's Kafka readiness health indicator for a producer or consumer service.
- Advanced: Design health checks so a Kubernetes readiness probe (Module 20) correctly stops routing traffic to a broker-disconnected instance.
