How do you set up a CI/CD pipeline for deploying serverless applications in AWS?
Asked on Nov 29, 2025
Answer
Setting up a CI/CD pipeline for deploying serverless applications in AWS involves using AWS services like CodePipeline, CodeBuild, and Lambda to automate the build, test, and deployment processes. This approach aligns with the AWS Well-Architected Framework, emphasizing operational excellence and automation.
- Access the AWS Management Console and navigate to AWS CodePipeline.
- Create a new pipeline and configure the source stage to connect to your code repository (e.g., GitHub, CodeCommit).
- Add a build stage using AWS CodeBuild to compile and package your serverless application, specifying a buildspec.yml file.
- Configure a deploy stage to use AWS Lambda or AWS Serverless Application Model (SAM) for deploying the application.
- Test the pipeline by committing changes to the repository and observing the automated build and deployment process.
Additional Comment:
- Ensure your IAM roles have the necessary permissions for CodePipeline, CodeBuild, and Lambda operations.
- Use AWS CloudFormation or SAM templates to define your serverless resources as infrastructure as code.
- Integrate AWS CodeDeploy for blue/green or canary deployments to minimize downtime and risk.
- Monitor pipeline execution and application performance using AWS CloudWatch and AWS X-Ray.
