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.RECOMMENDED BOOKSBen Evans & Jim Gough • Optimizing Cloud Native JavaBen Evans, Jason Clark & David Flanagan • Java in a NutshellBen Evans, Martijn Verburg & Jason Clark • The Well-Grounded Java DeveloperBen Evans, Jim Gough & Chris Newland • Optimizing JavaBen Evans & Martijn Verburg • The Well-Grounded Java DeveloperBlueskyInstagramLinkedInFacebookCHANNEL MEMBERSHIP BONUSJoin this channel to get early access to videos & other perks:https://www.youtube.com/channel/UCs_tLP3AiwYKwdUHpltJPuA/joinLooking for a unique learning experience?Attend the next GOTO conference near you!
