An organization has a distributed application running. This application is implemented with microservices architecture using AWS services including Lambda, API Gateway, SNS and SQS.
What is the cost-effective best way to analyze, debug and notify if any issues arise in production?

Answer options:

A.Use Cloud watch dashboard to monitor the application, create a cloud watch alarm to notify for any errors.
B.Use Cloud watch events to trigger a lambda and notify.
C.Use X-Ray to analyse and debug the application and use CloudWatch alarm to notify.
D.Use 3rd party tools to debug and notify.

Correct Answer : C
Option A is incorrect. Amazon cloud watch dashboards can help to monitor all the resources. You can have a single view and multiple view across all the AWS regions to see how things are going across the services. But it cannot give detailed debugging and monitoring of each service.
Option B is incorrect because a cloud watch event is created if any event happens in a service and can not be used for detailed analysis and debugging.
Option C is CORRECT as AWS X-ray collects data, analysis and debug of microservice application. Amazon X-Ray helps to analyze and debug modern applications. It will also collect the traces about the request from each of the applications. It also records the traces. After recording, it can create a view service map that can be seen to trace data latency and analyze the issues. This can help to find any unusual behavior to identify any root cause.
Option D is incorrect. Any custom monitoring tool will not help for detailed debugging of any microservices applications running on AWS.
