Why do Kubernetes liveness and readiness probes need different Spring Actuator endpoints?
PICTURE THIS: HOW JAVA RUNS
Simple meaning
Liveness should restart a deadlocked JVM
WHY — Microservices instead of guessing?
Why interviewers care about Microservices:
on Microservices.
the situation, the default choice, and one exception - that reads as experience.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Liveness should restart a
deadlocked JVM
- 2it must not fail
just because a dependency is down or you will crash-loop.
- 3Readiness should remove the
pod from the load balancer while the pool is warming or the DB is gone.
- 4Mixing them is a
classic outage amplifier.
- 5Common mistake
What juniors usually get wrong.
- 6Close

Key takeaway
