A company wants to migrate its content sharing web application hosted on Amazon EC2 to a serverless architecture. The company currently deploys changes to its application by creating a new Auto Scaling group of EC2 instances and a new Elastic Load Balancer, and then shifting the traffic away using an Amazon Route
53 weighted routing policy.
For its new serverless application, the company is planning to use Amazon API Gateway and flaws Lambda. The company will need to update its deployment processes to work with the new application. It will also need to retain the ability to test new features on a small number of users before rolling the features out to the entire user base.
Which deployment strategy will meet these requirements?

A. Use flaws CDK to deploy API Gateway and Lambda functions. When codefineeds to be changed, update the flaws CloudFormation stack and deploy the new version of the APIs and Lambda functions. Use a Route 53 failover routing policy for the canary release strategy.

B. Use flaws CloudFormation to deploy API Gateway and Lambda functions using Lambda function versions. When codefineeds to be changed, update the CloudFormation stack with the new Lambda code and update the API versions using a canary release strategy. Promote the new version when testing is complete.

C. Use flaws Elastic Beanstalk to deploy API Gateway and Lambda functions. When codefineeds to be changed, deploy a new version of the API and Lambda functions. Shift traffic gradually using an Elastic Beanstalk blue/green deployment.

D. Use flaws OpsWorks to deploy API Gateway in the service layer and Lambda functions in a custom layer. When codefineeds to be changed, use OpsWorks to perform a blue/green deployment and shift traffic gradually.
