Deep dive on tuning cloud apps: outlines challenges (variable workloads, distributed microservices, multi-tenancy) and a repeatable cycle: monitor/profile, find bottlenecks, optimize, verify; plus best practices (caching, DB query tuning, CDNs, right-sizing, autoscaling) and cloud-native tactics (serverless, containers/K8s, managed load balancers), with real cases proving big latency and UX gains.
