OPN304: Migrating AWS Lambda's front end from Java 8 to Java 11

In this session, we explore the journey of migrating AWS Lambda's front-end service from Java 8 to Java 11 using Amazon Corretto, our no-cost distribution of OpenJDK. We also walk through the code and dependency changes required to migrate to Java 11, how we measured performance improvements, and how we safely deployed such a significant update to a large-scale service across multiple regions in production.
