AOT - Ahead of Time

Ahead-of-Time (AOT) compilation is gaining significant traction—particularly in the context of cloud deployments, where optimizing performance and reducing costs are top priorities. By shifting certain workloads from runtime to build time, AOT enables more efficient, leaner deployments that consume fewer resources and start up faster. This session explores AOT techniques in the Java ecosystem, focusing on practical approaches to reducing runtime overhead. We'll look at the trade-offs and benefits of different strategies, including the use of GraalVM Native Image, and how they can contribute to more cost-effective, scalable Java applications in the cloud.
