Question 246

A DevOps engineer is setting up an Amazon Elastic Container Service (Amazon ECS) blue/green deployment for an application by using AWS CodeDeploy and AWS CloudFormation. During the deployment window, the application must be highly available and CodeDeploy must shift 10% of traffic to a new version of the application every minute until all traffic is shifted.

Which configuration should the DevOps engineer add in the CloudFormation template to meet these requirements?

Add an AppSpec file with the CodeDeployDefault.ECSLinearl OPercentEveryl Minutes deployment configuration.

Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the CodeDeployDefault.ECSLinear10PercentEvery1Minutes deployment configuration.

Add an AppSpec file with the ECSCanary10Percent5Minutes deployment configuration.

Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDepioy::BlueGreen hook parameter with the ECSCanary10Percent5Minutes deployment configuration.

Correct Answer: B

To set up an Amazon ECS blue/green deployment using AWS CodeDeploy and CloudFormation, you should use the AWS::CodeDeployBlueGreen transform along with the AWS::CodeDeploy::BlueGreen hook parameter. The specific deployment configuration to gradually shift traffic in increments of 10% per minute is defined by CodeDeployDefault.ECSLinear10PercentEvery1Minutes. This configuration ensures that 10% of the traffic shifts to the new version of the application every minute until the deployment is complete, which meets the requirement of having a highly available application during the deployment window.
