Tutorial: Deploy an updated Lambda function with CodeDeploy and the AWS Serverless Application Model (original) (raw)

AWS SAM is an open-source framework for building serverless applications. It transforms and expands YAML syntax in a AWS SAM template into AWS CloudFormation syntax to build serverless applications, such as a Lambda function. For more information, see What is the AWS Serverless Application Model?

In this tutorial, you use AWS SAM to create a solution that does the following:

• Creates your Lambda function.
• Creates your CodeDeploy application and deployment group.
• Creates two Lambda functions that execute deployment validation tests during CodeDeploy lifecycle hooks.
• Detects when your Lambda function is updated. The updating of the Lambda function triggers a deployment by CodeDeploy that incrementally shifts production traffic from the original version of your Lambda function to the updated version.

Topics

• Prerequisites
• Step 1: Set up your infrastructure
• Step 2: Update the Lambda function
• Step 3: Deploy the updated Lambda function
• Step 4: View your deployment results
• Step 5: Clean up
