DVA-C02 Question 231
Select 3You are developing a serverless application using AWS Lambda and have integrated the codebase with a Git-based version control system. Your team wants to implement a CI/CD pipeline that automatically deploys updates to the Lambda function whenever changes are pushed to the 'main' branch. Which AWS services and configurations should you use to achieve this?
- A
Use AWS CodePipeline to define the CI/CD pipeline and configure it to trigger deployments on changes to the 'main' branch.
- B
Configure AWS CodeCommit as the Git-based repository and set up a trigger to invoke the Lambda function directly when changes are pushed to the repository.
- C
Use AWS CodeBuild to compile, test, and package the Lambda function code as part of the pipeline.
- D
Use AWS CloudFormation to define the Lambda function and its configurations as code and integrate it into the deployment step of the pipeline.
- E
Manually deploy the updated Lambda function from your local machine whenever changes are merged into the 'main' branch.
Show answer and explanation
Correct answers: A, C, D
Explanation
To implement a CI/CD pipeline for deploying updates to a Lambda function, you can use AWS CodePipeline to define the workflow, AWS CodeBuild to handle code compilation and testing, and AWS CloudFormation to manage the deployment of the Lambda function as infrastructure as code. This ensures a fully automated and scalable CI/CD process. Manually deploying changes or directly triggering Lambda from repository changes does not align with best practices for CI/CD.
- A. Correct.
Correct. AWS CodePipeline is designed for CI/CD workflows and can be configured to trigger deployments based on changes to specific branches in a Git-based repository.
- B. Incorrect.
Incorrect. While AWS CodeCommit can store your code, directly triggering a Lambda function from CodeCommit changes isn't a best practice for CI/CD pipelines.
- C. Correct.
Correct. AWS CodeBuild is a critical part of the CI/CD process, as it handles the build, test, and package phases for your code.
- D. Correct.
Correct. AWS CloudFormation ensures your Lambda function and its configurations are managed as infrastructure as code and allows seamless integration into automation pipelines.
- E. Incorrect.
Incorrect. Manually deploying changes is not an automated or scalable approach, which is contrary to CI/CD best practices.
