AWS Certified Developer Associate DVA-C02 Practice Question
An application development team has implemented a system of microservices and requires a method to transparently diagnose issues that may arise during the traversal of requests across multiple service boundaries. Which service would provide them with the ability to track these requests, analyze performance bottlenecks, and visualize the service interaction?
The correct service for the described needs is AWS X-Ray. This service is specifically designed to help developers analyze and debug both production and distributed applications, such as those built with a microservices architecture. It provides an end-to-end view of requests as they journey through your application, and it constructs a detailed service map that visualizes the application’s architecture. While services like CloudTrail and VPC Flow Logs are useful for their own specific use cases (API activity monitoring and network traffic logging, respectively), they do not offer the dedicated tracing or application topology visualization capabilities that AWS X-Ray provides. Similarly, Amazon CloudWatch focuses primarily on monitoring operational metrics and logs, and it doesn't offer the same comprehensive tracing or service mapping that is native to AWS X-Ray.
