[All AWS Certified Developer Associate Questions]

A Developer must analyze performance issues with production-distributed applications written as AWS Lambda functions. These distributed Lambda applications invoke other components that make up the applications.
How should the Developer identify and troubleshoot the root cause of the performance issues in production?

A. Add logging statements to the Lambda functions, then use Amazon CloudWatch to view the logs.
B. Use AWS CloudTrail and then examine the logs.
C. Use AWS X-Ray, then examine the segments and errors.
D. Run Amazon Inspector agents and then analyze performance.

Selected Answer: C

C) Correct - AWS X-Ray is the most suitable service for identifying and troubleshooting performance issues in production-distributed applications, including those built using AWS Lambda functions. It provides a deep, end-to-end view of requests as they travel through your Lambda functions and the other components they interact with (such as databases, queues, APIs, etc.).

B) Eliminated - AWS CloudTrail logs API calls and is useful for auditing and tracking who made requests to AWS services. However, it doesn't provide detailed performance or latency data for troubleshooting distributed application performance. It is more focused on security and compliance rather than performance analysis.

A) Eliminated - While CloudWatch Logs can be useful for simple logging and debugging, it doesn't provide the level of visibility needed for distributed applications, especially when there are performance issues that involve multiple services

C. Use AWS X-Ray, then examine the segments and errors is the recommended option. X-Ray provides a comprehensive view of the entire request path, making it easier to identify performance issues with other AWS resources or downstream services, and to understand the cause of errors. X-Ray provides detailed trace data, including performance data, errors, and metadata, that helps you identify and troubleshoot performance issues in your production-distributed applications written as AWS Lambda functions.

X-Ray helps you analyze and debug distributed applications, such as those built using a microservices architecture. Using X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root causes of performance issues and errors. It helps you debug and triage distributed applications wherever those applications are running, whether the architecture is serverless, containers, Amazon EC2, on-premises, or a mixture of all of these.
