CodeDeploy supports TimeBasedLinear traffic shifting for ECS blue/green deployments. Traffic increments by linearPercentage every linearInterval until 100%. This provides zero-downtime gradual rollout — as per CodeDeploy ECS Blue/Green Traffic Shifting documentation.

To restrict access to S3 buckets so that only IAM principals from within the AWS Organization can access them, an SCP (Service Control Policy) with conditions using the aws:PrincipalAccount or preferably aws:PrincipalOrgID can be applied at the OU level.

SCPs restrict the maximum permissions for IAM entities in member accounts and can be used to enforce access control policies across accounts.

The aws:PrincipalAccount condition restricts access to principals from specific accounts, while aws:PrincipalOrgID restricts based on the organization ID.

IAM permissions boundaries (Option B) cannot be applied organization-wide and do not enforce restrictions across accounts.

AWS RAM (Option C) is for sharing resources but does not restrict S3 bucket access based on organizational principals.

There is no such thing as an RCP in AWS Organizations (Option D is invalid).

The condition is deterministic: maximum CPU utilization must be below 2% for the previous 24 one-hour periods. That requires a static threshold, not anomaly detection. Anomaly detection learns a normal band from historical behavior, which is useful for unusual patterns but not for a fixed business definition of “idle.” CloudWatch alarms use “Datapoints to Alarm” as an M-out-of-N evaluation model, so 24 out of 24 means all 24 hourly datapoints must breach the threshold. AWS also documents idle-instance alarm examples based on CPU utilization staying below a threshold for 24 consecutive periods. Option D would alarm if only one hour was below 2%, which is far too sensitive. Options A and C use the wrong threshold type.
