"Spot instances are too risky for production." I hear this all the time. Let me prove you wrong ๐Ÿงต๐Ÿ‘‡

ALT Animated diagram showing Karpenter Spot interruption handling in 6 stages. Stage 1: Normal operation with 5 pods on Spot Node-1. Stage 2: AWS sends interruption warning via EventBridge to SQS, Karpenter detects. Stage 3: First eviction wave, Pod-1 and Pod-2 migrate to new Node-2, PDB enforces minAvailable 3. Stage 4: Second eviction wave, remaining pods migrate. Stage 5: Old node terminates, all pods on Node-2. Stage 6: Migration complete, zero downtime achieved, all 5 pods running stable on new Spot node.

The math: On-Demand: $100/month Spot: $30/month (70% savings) "But what about interruptions?" โ€ข Interruption rate: ~5%/month โ€ข Recovery time: 90 seconds โ€ข Service impact: ZERO You're paying 3x more for "stability" you don't need.
