CyberAgent used generative AI to review about 200 live Lambda functions and refactor 38

Japanese internet company CyberAgent said on its engineering blog that it used generative AI to catalog about 200 AWS Lambda functions, small cloud programs running in production and managed by multiple people. It refactored and redeployed 38 of them. Risky steps such as production deploys required explicit approval from a human engineer.
