If one burns out, it automatically replaces it to maintain your desired count. 🔹  Deployment = Smart Home System The intelligent orchestrator that: ✅ Controls the number of bulbs (like ReplicaSet) ✅ Seamlessly upgrades to new, energy-efficient models (rolling updates) ✅ Rolls back to old bulbs if the new ones flicker (rollback capability) Why this matters:  Understanding these core concepts is essential for anyone working with containerized applications. Each layer adds more intelligence and automation to your infrastructure. What's your favorite analo...
