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?

This corresponds to Option B: Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the CodeDeployDefault.ECSLinear10PercentEvery1Minutes deployment configuration.

I’m leaning towards A, but I’m a bit confused about the AppSpec file's role in this context. I thought it was more about defining the deployment process rather than the traffic shifting.

I practiced a similar question, and I feel like the ECSCanary10Percent5Minutes option might not fit since we need to shift traffic every minute, not every five minutes.

I'm not entirely sure, but I remember something about ECSLinear10PercentEvery1Minute being the right configuration for shifting traffic gradually.

I think the answer might be B because it mentions the AWS::CodeDeployBlueGreen transform, which seems crucial for blue/green deployments.

The requirement to shift 10% of traffic every minute is the tricky part. I'll need to double-check the available deployment configurations to make sure I select the right one.

Okay, the key here is to use the AWS::CodeDeployBlueGreen transform and the appropriate hook parameter to configure the blue/green deployment. I think option B is the way to go.

Okay, let me break this down. The key seems to be identifying which statements align with the core principles of Beyond Budgeting, like adaptive management and decentralized structures.

Hmm, I wonder if the DevOps engineer is feeling a bit 'blue' about this deployment. Get it? 'Blue/green' deployment? I'll see myself out.

I'm not sure, but it makes sense to gradually shift the traffic during deployment to ensure high availability. So, I think B is the correct answer.

Hold up, I think Option C might be a better fit. The ECSCanary10Percent5Minutes configuration seems to match the requirement more closely.
