Free AWS Certified Developer Associate DVA-C02 Practice Question

A software company utilizes AWS Lambda for deploying a mission-critical application. In their upcoming release, they plan to incorporate a canary release strategy to introduce a new feature incrementally while mitigating risks. Assuming they already have a Lambda alias for their production environment, how should the company configure the alias to slowly route a small percentage of user traffic to the new feature while the majority still accesses the stable version?

  • Adjust the production alias to serve both the old and the new Lambda versions, and configure the alias routing with a small weight towards the new version, gradually increasing it based on the monitoring results.

  • Configure the Lambda alias to immediately redirect 100% of traffic to the new version to test the new feature in live conditions.

  • Deploy the new version as a separate Lambda function without an alias and manually invoke the new function to represent a percentage of total traffic.

  • Deploy the new feature as a new Lambda function and update the production alias configuration to point solely to the new function, relying on Lambda's inherent traffic shifting capabilities.
