Answer
Readiness prevents routing traffic to uninitialized Pods.
Quick Answer
Without readiness probes, Kubernetes assumes a container is ready as soon as it starts — but the app might still be initializing (loading cache, connecting to DB). Traffic sent to an unready Pod returns errors. A readiness probe ensures traffic only reaches Pods that are actually ready to serve. Critical for zero-downtime deployments.
