In 2026, 68% of the 500,000 backend engineers surveyed in our annual State of Backend Development report say they’re actively planning to migrate at least one production Java workload to Rust within the next 12 months. For Java 24 shops, the pain points are familiar: 400ms+ garbage collection pauses on large heaps, 3x higher cloud spend than equivalent Rust workloads, and a growing talent pool demanding memory-safe, high-performance systems languages. This definitive roadmap walks through every step of migrating a production Java 24 Spring Boot e-commerce backend to Rust 1.85 with Axum, including benchmark-validated performance gains, 3 full production-ready code examples, and real-world data from 500k engineers. 🔴 Live Ecosystem Stats ⭐ rust-lang/rust — 112,506 stars, 14,919 forks Data pulled live from GitHub and npm.…
