DESCRIPTION
Holly Cummins talks with Ben Evans about his latest book "Optimizing Cloud Native Java", which updates his previous work "Optimizing Java" to reflect the realities of cloud native environments.
Ben explains that performance engineering is not just technical but also psychological, emphasizing the importance of user expectations and defining clear performance goals. They discuss how modern Java performance must account for cloud native architectures, with applications running across distributed microservices and containerized, single-core environments.
The book focuses on the importance of measuring relevant data, warns against relying on misleading micro-benchmarks, and highlights how system-level benchmarks offer a clearer picture. Ben also delves into the JVM's hidden complexities, such as changes in Java 17 and the impact of virtual threads. Practical, real-world examples in the book, like the "fighting animals" microservices application, help developers learn how to optimize Java performance in real network environments.
Finally, Ben touches on the future of Java concurrency, with virtual threads and structured concurrency offering new ways to handle performance challenges in cloud native systems.
