Cost Optimization:?

Q: Cost Optimization:?

Short answer: Serverless: Use serverless compute options like AWS Lambda, Azure Functions, or Google Cloud Functions for burstable or event-driven workloads to avoid idle time. Explain a bit more Spot Instances: Use spot instances or preemptible VMs for non-critical workloads that can tolerate interruptions, reducing costs significantly. Resource Scaling: Configure autoscaling policies to match service demand, ensuring you’re only paying for the resources you need. Real-world example (ShopNest) ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments. Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
