AWS Spot Interruption Rates Under 5% for Most Instance Types — Production Viable

AWS Spot interruption rates dropped below 5% for most instance types in major regions. m5.large, c5.xlarge under 2% in us-east-1. Singapore m6i and c6i under 3%. 6-10 instance types across 3 AZs = near-zero real-world interruptions.

TCOIQ: Low rates make Spot viable for production web tiers with load balancing. Savings remain 60-70% vs On-Demand. Implement: CI/CD first (zero risk), then ML training with checkpointing, then production with 20% On-Demand baseline.
