Why the JVM Is Still Dominant in Production in 2026

Lucas and Luna dig into why the Java Virtual Machine, despite being over three decades old, remains the runtime of choice for mission-critical backend systems in 2026. They examine Project Loom's virtual threads, which have slashed latency for concurrent applications, and compare GraalVM's native-image compilation against Go's compiled binaries. The conversation cites real numbers: how a major trading platform cut p99 latency from 12 milliseconds to under 2 milliseconds using virtual threads, and why the JVM's mature garbage collectors handle multi-terabyte heaps more predictably than newer runtimes. The hosts also discuss the JVM's expanding role in data engineering through Apache Spark and its synergy with Kotlin.
