No More Xmx - Adaptable Heap Sizing for Containerized Java Applications

Discover Google's innovative solution for memory management of Java applications in containerized environments. Learn about Adaptable Heap Sizing (AHS), a project that eliminates the need for manual tuning of maximum heap size (--Xmx) and automatically adjusts Java heap usage based on container limits and usage. Explore the challenges of Java memory configuration in containers, the history of memory issues at Google, and how AHS improves application stability while often reducing memory usage. Gain insights into optimizing Java performance in containerized environments and understand the potential impact on both performance and cost. This 50-minute Devoxx conference talk, presented by Jonathan Joo, a senior software engineer on Google's Java Platform Team, offers valuable knowledge for developers working with Java in containers or seeking to enhance their understanding of memory management in containerized applications.
