Java on IBM Z: Evolving for the Future of Enterprise Workloads

Abstract:
Java remains a cornerstone for enterprise workloads on IBM Z, driving mission-critical applications with exceptional reliability, scalability, and performance. In this session, we’ll explore how Java continues to evolve on IBM Z—especially with the introduction of the latest IBM z17 system—to meet the demands of modern, cloud-native workloads and accelerate application modernization.We’ll begin with a look at current Java adoption trends on the platform, followed by a deep dive into the performance metrics that matter most to our customers: startup time, response latency, and throughput. You’ll learn how innovations in the JVM and hardware-level enhancements in IBM Z are helping us push the boundaries of what’s possible.Join us to discover how Java on IBM Z is not only keeping pace with modern application demands but also setting new standards for performance, security, and integration in hybrid cloud environments.
