Explanation:

Tracing Distributed Systems:AWS X-Ray is designed to trace requests across services, helping identify bottlenecks in distributed applications like this one.

No Code Changes:Enabling X-Ray tracing often requires minimal code changes, meeting the requirement.

Identifying Bottlenecks: Analyzing X-Ray traces and logs will reveal latency in communications between different AWS services, leading to the high duration time.
