Which action will allow an Administrator to understand the impact of these changes before implementation?
Implement a blue/green strategy using AWS Elastic Beanstalk.
Perform a canary deployment using Application Load Balancers and target groups.
Create a change set for the running stack.
Submit the update using the UpdateStack API call.
Explanations:
A blue/green deployment strategy using AWS Elastic Beanstalk is primarily used for application deployments and not for reviewing changes in CloudFormation stacks. It focuses on minimizing downtime during application updates.
A canary deployment is a method of rolling out changes gradually, primarily in the context of application deployments, using Application Load Balancers and target groups. It doesn’t directly apply to reviewing CloudFormation stack changes.
Creating a change set for the running stack in AWS CloudFormation allows the administrator to preview the changes that will be applied to the stack. It provides a detailed list of changes before they are executed.
The UpdateStack API call directly submits updates without reviewing the changes first. It is not used for understanding the impact of changes before implementation.
I outline that the answer is:
Create a change set for the running stack.
I chart that the answer is:
