Correct answer - "AWS X-Ray" : AWS X-Ray is a service that collects data about requests that your
application serves, and provides tools you can use to view, filter, and gain insights into that
data to identify issues and opportunities for optimization. For any traced request to your
application, you can see detailed information not only about the request and response, but also
about calls that your application makes to downstream AWS resources, microservices, databases
and HTTP web APIs.

"VPC Flow Logs" - VPC Flow Logs is a feature that enables you to capture information about the IP
traffic going to and from network interfaces in your VPC. Flow log data can be published to
Amazon CloudWatch Logs and Amazon S3. After you've created a flow log, you can retrieve and view
its data in the chosen destination.
Flow logs can help you with a number of tasks; for example, to troubleshoot why specific traffic
is not reaching an instance, which in turn helps you diagnose overly restrictive security group
rules. You can also use flow logs as a security tool to monitor the traffic that is reaching
your instance.
"CloudWatch Events" - Amazon CloudWatch Events delivers a near real-time stream of system events
that describe changes in Amazon Web Services (AWS) resources. Using simple rules that you can
quickly set up, you can match events and route them to one or more target functions or streams.
CloudWatch Events becomes aware of operational changes as they occur. CloudWatch Events responds
to these operational changes and takes corrective action as necessary, by sending messages to
respond to the environment, activating functions, making changes, and capturing state
information.
"CloudTrail" - AWS CloudTrail is a service that enables governance, compliance, operational
auditing, and risk auditing of your AWS account. With CloudTrail, you can log, continuously
monitor, and retain account activity related to actions across your AWS infrastructure.
CloudTrail provides event history of your AWS account activity, including actions taken through
the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event
history simplifies security analysis, resource change tracking, and troubleshooting.
