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.

Step 1: Reacting to RDS Storage Autoscaling Events Using Amazon EventBridgeAmazon RDS emits events when storage autoscaling occurs. To visualize these events in a CloudWatch dashboard, you can create an EventBridge rule that listens for these specific autoscaling events.

Action: Create an EventBridge rule that reacts to RDS storage autoscaling events from the RDS event stream.

Why: EventBridge allows you to listen to RDS events and route them to specific AWS services for processing.

Step 2: Creating a Custom CloudWatch Metric via LambdaOnce the EventBridge rule detects a storage autoscaling event, you can use a Lambda function to publish a custom metric to CloudWatch. This metric can then be visualized in a CloudWatch dashboard.

Action: Use a Lambda function to publish custom metrics to CloudWatch based on the RDS storage autoscaling events.

Why: Custom metrics allow you to track specific events like autoscaling and visualize them easily on a CloudWatch dashboard.

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.
