Quick Answer
Cloud-native optimization for cost and performance: right-size instances (don't over-provision), use spot/preemptible instances for stateless services, auto-scale to zero for low-traffic services (KEDA), use managed services instead of running your own (saves ops overhead). Performance: caching at every layer, async where possible, efficient serialization, connection pooling, CDN for static content.
Answer
Use autoscaling to match demand. Prefer stateless services for efficient scaling. Use serverless or managed services to reduce operational cost.
