A DevOps team manages a high-traffic web application where performance is critical. They need to analyze user request patterns, identify performance bottlenecks, and detect anomalies in real-time. The application uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. The solution must provide end-to-end visibility of requests and automatically identify deviations from normal behavior. Which combination of AWS services should the team implement?
- AAWS X-Ray for distributed tracing, Amazon CloudWatch for metrics and logs, and CloudWatch Anomaly Detection.
- BAWS Budgets for cost monitoring, Amazon SNS for notifications, and AWS Step Functions for workflow orchestration.
- CAWS CloudTrail for API activity, Amazon S3 for log storage, and AWS Config for resource changes.
- DAmazon Kinesis Data Firehose for log ingestion, Amazon OpenSearch Service for log analysis, and AWS WAF for security.
Show answer & explanationAnswer & explanation
Correct answer: A. AWS X-Ray for distributed tracing, Amazon CloudWatch for metrics and logs, and CloudWatch Anomaly Detection.
AWS X-Ray provides end-to-end visibility and distributed tracing for requests across API Gateway, Lambda, and DynamoDB, helping identify performance bottlenecks. Amazon CloudWatch collects metrics and logs from these services. CloudWatch Anomaly Detection automatically identifies deviations from normal patterns in metrics, fulfilling the requirement to detect anomalies in real-time. This combination provides comprehensive monitoring and anomaly detection for the described serverless application.
Why the other options are wrong
- B. These services are for cost management, notifications, and workflow orchestration, respectively, not for performance monitoring, tracing, or anomaly detection for application behavior.
- C. CloudTrail logs API calls, S3 stores logs, and AWS Config tracks resource changes; none provide real-time performance analysis, end-to-end tracing, or anomaly detection.
- D. Kinesis Firehose and OpenSearch are for log ingestion and analysis, but they do not inherently provide end-to-end request tracing or automatic anomaly detection on metrics.
X-Ray, CloudWatch, Anomaly Detection Combo
A powerful combination of AWS services for comprehensive monitoring: X-Ray for distributed tracing, CloudWatch for metrics/logs, and Anomaly Detection for automated deviation detection.
- X-Ray visualizes end-to-end request flow and identifies latency.
- CloudWatch collects all application and service metrics/logs.
- Anomaly Detection automatically learns normal metric patterns and alerts on deviations.
Memory trick: X-Ray traces, CloudWatch measures, Anomaly Detection warns.
