EC2 vs Lambda vs Fargate for Web Performance
Compute choice affects startup behavior, scaling, deployment, and operational control, but user latency depends on the full request path. Compare EC2, Lambda, and Fargate by workload shape rather than service reputation.

AWS CloudFront Performance: Caching, Compression, and Origins
CloudFront improves performance when it serves useful work close to viewers and shields the origin from repetition. The real optimization target is the cacheable request path, not the existence of a distribution.

AWS Lambda Cold Starts: Measure, Diagnose, and Reduce Them
A Lambda cold start occurs when no suitable execution environment is ready and AWS must create and initialize one. Optimize it as a tail-latency event inside the full request path.
