Question

A team deploys a serverless payment-processing function using AWS CodeDeploy with a Lambda compute platform. They want each new version to receive 10% of traffic every 2 minutes until fully shifted, and they require an automated validation that runs BEFORE any production traffic reaches the new version. If the validation fails, the deployment must stop and no traffic should be shifted. Which configuration meets these requirements?

Accepted Answer

Use the LambdaLinear10PercentEvery2Minutes deployment configuration and add a BeforeAllowTraffic hook that invokes a validation Lambda function.

Answer

Use the LambdaCanary10Percent5Minutes deployment configuration and add a BeforeAllowTraffic hook that invokes a validation Lambda function.

Answer

Use the LambdaLinear10PercentEvery2Minutes deployment configuration and add an AfterAllowTraffic hook that invokes a validation Lambda function.

Answer

Use the LambdaAllAtOnce deployment configuration with a CloudWatch alarm-based rollback on the function's error metric.
