Exam AWS Certified Solutions Architect - Professional topic 1 question 464 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 464
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A Development team is deploying new APIs as serverless applications within a company. The team is currently using the AWS Management Console to provision
Amazon API Gateway, AWS Lambda, and Amazon DynamoDB resources. A Solutions Architect has been tasked with automating the future deployments of these serverless APIs.
How can this be accomplished?

  • A. Use AWS CloudFormation with a Lambda-backed custom resource to provision API Gateway. Use the AWS::DynamoDB::Table and AWS::Lambda::Function resources to create the Amazon DynamoDB table and Lambda functions. Write a script to automate the deployment of the CloudFormation template.
  • B. Use the AWS Serverless Application Model to define the resources. Upload a YAML template and application files to the code repository. Use AWS CodePipeline to connect to the code repository and to create an action to build using AWS CodeBuild. Use the AWS CloudFormation deployment provider in CodePipeline to deploy the solution.
  • C. Use AWS CloudFormation to define the serverless application. Implement versioning on the Lambda functions and create aliases to point to the versions. When deploying, configure weights to implement shifting traffic to the newest version, and gradually update the weights as traffic moves over.
  • D. Commit the application code to the AWS CodeCommit code repository. Use AWS CodePipeline and connect to the CodeCommit code repository. Use AWS CodeBuild to build and deploy the Lambda functions using AWS CodeDeploy. Specify the deployment preference type in CodeDeploy to gradually shift traffic over to the new version.

I would go for D, SAM only works in CLI and the team is currently using the AWS Management Console to provision Amazon API Gateway, AWS Lambda, and Amazon DynamoDB resources.

Because team is using Console --> need to improve for future automation deployment and not using Console any more. B is my choice.

Codedeploy will not deploy Lambda functions. So the answer is B.

Actually it's still sam. CodeDeploy only controls the traffic.

Selected Answer: B
Solution D uses CodeCommit, CodeBuild, and CodeDeploy to deploy the serverless application. However, it does not use SAM to define the application. This means that the development team would need to write their own YAML template, which can be complex. Therefore, the best solution is B. Here are some additional benefits of using SAM and CodePipeline: They are easy to use and manage. They are reliable and secure. They are cost-effective.

B - If you want to deploy your AWS SAM application gradually rather than all at once, you can specify deployment configurations that AWS CodeDeploy provides.
