Deep dive on serverless Java performance tuning on AWS, highly actionable.
AWS Hero Vadym Kazulkin presents a technical deep dive into overcoming Java's cold start and memory footprint challenges on AWS Lambda, comparing fully managed SnapStart with pre-snapshot priming hooks against GraalVM ahead-of-time compilation. He addresses the latest architectural implications of Project Leyden and Java 25, noting that Java adoption on Lambda remains in the single-digit percent range despite its enterprise popularity, primarily due to startup latency and cost factors. The talk covers practical tuning strategies including Amazon Corretto support timelines and the gap between Java 21 and upcoming Java 25 Lambda support.
