Your question is Frontend Performance with Serverless Backend. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe how you would optimize the performance of a front-end application connected to a serverless back-end on AWS.
Cover how you would identify the dominant bottleneck before changing code, then improve browser execution, asset delivery, API requests, Lambda execution, and data access. Explain the trade-offs between caching, payload reduction, concurrency, cold-start mitigation, and consistency.
Scope: discuss a web application using Amazon CloudFront, Amazon S3, Amazon API Gateway, AWS Lambda, and Amazon DynamoDB.
