Answer
Private registries provide access control, compliance, privacy, and no rate limits.
Quick Answer
Private registries give companies control over access, SLA, scanning, and retention. Docker Hub is public by default, has rate limits, and can go down (affecting all your deployments). Private registries (ECR, GCR, Harbor) live in your own infrastructure, support role-based access, and integrate with vulnerability scanners.
