A company operates a media streaming platform that delivers on-demand video content to users from...

Requirement Summary:

Users experiencebuffering/delaywhen starting video stream

Architecture:

CloudFront → API Gateway → Lambda → DynamoDB

Need toidentify root causeof performance issues

Evaluate Options:

✅A: Enable AWS X-Ray tracing

✅Ideal forend-to-end tracing

Visualizeslatency across services (API Gateway, Lambda, DynamoDB)

Creates aservice mapfor easy identification of bottlenecks or errors

Designed specifically fordistributed tracingand performance monitoring

B: CloudWatch Logs Insights

⚠️Helpful for querying logs

But lacks thevisual trace linkageacross services like X-Ray

Does not identifywhere latency accumulates

C: AWS Config

❌Tracks configuration changes,not runtime performance

D: CloudTrail + CloudWatch Logs

❌More useful foraudit/logging, not tracing performance or latency issues
