AWS re:Invent 2019: [REPEAT 1] Best practices for AWS Lambda and Java (SVS403-R1)

Published on Dec 07, 2019

In this session, we follow a customer’s journey as they optimize an AWS Lambda function written in Java to meet their cold start time requirements. We start from a simple yet slow PoC and walk through all of the changes, tricks, and trade-offs we made to reduce the cold start time by over 70%. Finally, we explore new technologies such as Quarkus and GraalVM that can make Java even faster in Lambda.
