The modern Java Virtual Machine (JVM) is the culmination of millions of hours of expert engineering, and is the foundation on which enormous portions of the digital landscape are built. However, as a runtime for AWS Lambda functions, it is often derided as a poor fit for an ephemeral world. However, the JVM is an excellent choice of runtime for a wide range of AWS Lambda use cases, and developers don’t need to constrain themselves to just the Java language to use it. In this chalk talk, Symphonia’s John Chapin gives a brief overview of AWS Lambda development using Java and Maven, outlines use cases (good and bad), and gives strategies and tips for developing performant JVM-based AWS Lambda functions. An extensive Q&A and whiteboarding session follow the presentation.
