Building Bulletproof Concurrent Applications on the JVM
summary
Argues that the JVM is suddenly practical for cloud native work thanks to ZGC and Shenandoah for low GC latency, Graal reducing startup to milliseconds and Loom virtual threads plus ZIO fibers for massive concurrency. Shows ZIO (Scala) provides statically typed error channels, composable retry schedules, scoped resource safety, testable simulated clocks, lazy streaming and fiber cancellation; cites Capital One and Disney Streaming adopters, a real-world $1M→$100k monthly infra savings example, and notes Scala is required to use ZIO today.
