Major Companies Are Switching to Rust: Trend 2025
2025 has become a turning point for the software development industry. More and more tech giants are announcing large-scale migrations of critical systems to the Rust programming language. While Rust was once considered a niche tool for systems programmers, today it is turning into a strategic standard for infrastructure projects.
Why Rust?
The main reason is memory safety at compile time. Unlike C and C++, Rust guarantees the absence of memory leaks and data races without using a garbage collector. This is critical for:
- Cloud services — reducing the number of vulnerabilities (Microsoft reported a 70% reduction in critical bugs after migrating part of Azure to Rust).
- Browser engines — Google already uses Rust in Chrome for font and media processing components, while Firefox completely rewrote its CSS parser in Rust.
- Blockchain projects — Solana, Polkadot, and Near Protocol were originally written in Rust due to requirements for determinism and performance.
Who has already switched in 2025?
The list of companies is impressive:
- Amazon Web Services (AWS) — rewriting the core of S3 and Lambda in Rust. According to engineers' estimates, this reduced maintenance costs by 35%.
- Microsoft — integrating Rust into the Windows kernel through the Rust for Windows project. Drivers for network adapters and the file system have already been rewritten.
- Meta (Facebook) — Rust is used in the dependency management system Buck2 and in Instagram's rendering module.
- Cloudflare — fully switched to Rust for processing DNS queries (the Pingora project), which increased throughput by 40%.
What does this mean for developers?
The trend of 2025 is not just a fad. Rust is becoming a mandatory skill for DevOps, database developers, and embedded engineers. Even the Python developer community is actively adopting Rust: libraries like PyO3 allow creating fast modules for Python in Rust (for example, accelerating NumPy operations by 10 times).
If you plan to stay in demand in 3-5 years, now is the best time to start learning Rust. At PythonLib, we have prepared a selection of materials to get you started: from basic syntax to integration with existing Python projects.
Summary
Rust is not a replacement for Python, but a powerful addition to it. Companies choose Rust not for hype, but for real savings: fewer errors, higher performance, easier maintenance. 2025 shows that even giants that have been using C++ and Java for decades are ready for change. Are you ready?
