Optimizing Containerized Java Apps with Jib, GraalVM, CDS, and CRaC

Track: Cloud Native

Abstract

In today’s cloud-native world, keeping microservices reliable and scalable is essential. Java Java developers and architects often struggle to optimize containerized Java apps because configuring and integrating powerful tools into their build processes is complex. This session explores practical techniques to improve performance in cloud environments, including creating custom JREs, using Jib for easier container builds, and leveraging GraalVM for faster startup times. You’ll learn to use Class Data Sharing (CDS) and CRaC to improve startup times, while evaluating trade-offs to choose the best optimization techniques, ensuring your applications are optimized for scale, reliability, and efficiency in the cloud.
