AWS X-Ray provides distributed tracing, which allows visualization of latencies and errors within microservices, pinpointing bottlenecks or delays.

Instrumenting application code with the X-Ray SDK and running the X-Ray daemon as a DaemonSet in EKS ensures tracing data is collected cluster-wide.

Container Insights (Option B) provides resource-level metrics but not detailed request tracing.

CloudWatch alarms and alerts (Option C) detect symptoms but don ' t provide root cause tracing.

Increasing timeouts (Option D) only masks the issue and does not diagnose it.

Service-managed StackSets are the correct low-overhead deployment model when AWS Organizations trusted access is enabled. CloudFormation creates and manages the required StackSet execution roles, so self-managed permissions are unnecessary. However, AWS explicitly states that service-managed StackSets do not deploy stacks to the organization management account, even if the management account is part of the organization or belongs to an OU. Therefore, targeting the root OU deploys to the member accounts, but the management account still needs a separate normal CloudFormation stack. Option B is the only answer that covers both the member accounts and the management account with the least operational overhead. Option A misses the management account, while C and D require unnecessary self-managed role administration.

To meet the new guideline for application deployment, the company can use a combination of AWS CodePipeline and AWS CloudTrail. A manual approval action in CodePipeline allows the security team to review and approve changes before they are deployed. This action can be configured to pause the pipeline until approval is granted, ensuring that no changes move to production without the necessary sign-off. Additionally, by creating an AWS CloudTrail trail, all actions taken within CodePipeline, including approvals, are recorded and delivered to an Amazon S3 bucket. This provides an audit trail that can be retained for compliance and review purposes.

AWS CodePipeline’s manual approval action provides a way to ensure that a member of the security team can review and approve changes before they are deployed1.

AWS CloudTrail integration with CodePipeline allows for the recording and retention of all pipeline actions, including approvals, which can be stored in Amazon S3 for record-keeping2.
