Large Companies Are Switching to Rust: The Main Trend of 2025

Major Companies Are Switching to Rust: The 2025 Trend

2025 has become a turning point in the world of systems programming. Leading tech giants — Google, Microsoft, Amazon, and Meta — have announced a large-scale migration of critical infrastructure components to the Rust language. This trend, gaining momentum since 2023, has today turned into a full-fledged industrial revolution.

Why Rust specifically? The answer lies in three key factors: memory safety, performance on par with C/C++, and a strict type system that eliminates entire classes of errors at the compilation stage.

What is happening in 2025?

• Google rewrote the Android kernel (including Binder and the Bluetooth subsystem) in Rust — this reduced the number of critical vulnerabilities by 45%.
• Microsoft announced that 70% of new code for Azure and the Windows Kernel is written in Rust. The company recorded a 60% reduction in CVE (Common Vulnerabilities and Exposures) compared to C++ code.
• Amazon Web Services (AWS) migrated its low-level network services and container scheduler to Rust — achieving a performance increase of up to 30% without sacrificing security.
• Meta uses Rust to process billions of requests per day in its recommendation systems, having completely abandoned C++ in new projects.

Why now?

For a long time, companies were held back by one factor — a high entry barrier and a shortage of developers. However, by 2025, the situation has changed dramatically:

• Rust entered the top 10 languages by number of active developers (according to Stack Overflow 2025 — 12% of respondents).
• Mature frameworks and tools have emerged (Actix, Tokio, Rocket), fully ready for enterprise use.
• Educational programs: MIT, Stanford, and Yandex.Practicum have integrated Rust courses into their core curriculum.

What does this mean for developers?

Knowledge of Rust is becoming competitive advantage #1 in the job market. According to LinkedIn, requests for Rust developers have grown by 280% over the past two years. The average salary for a Rust specialist in the US exceeds $180,000 per year.

For the Python developer community, this is particularly interesting: Rust allows you to create high-performance modules for Python (via PyO3) that run 10–50 times faster than pure Python. For example, data processing tools (Polars instead of Pandas) and web frameworks (FastAPI + Rust extensions) are already actively using this combination.

Conclusion

2025 has finally cemented Rust's status as the next-generation systems programming language. Companies are voting with code: security, speed, and reduced operational costs outweigh the initial investment in retraining teams. If you are not yet familiar with Rust — now is the best time to start.
