Major Companies Are Switching to Rust: The Main Development Trend of 2025

2025 has become a turning point for the software development industry. More and more tech giants are announcing large-scale migrations of their key projects to the Rust language. This language, once considered niche, is now confidently taking the position of the "gold standard" for systems programming, leaving C, C++, and even Go behind.

Why Rust specifically? The answer lies in three pillars: memory safety, performance, and a growing community. Companies are tired of vulnerabilities related to buffer overflows (which account for over 70% of all critical bugs according to Microsoft), and Rust offers a compiler that simply prevents such errors from occurring. At the same time, Rust is comparable in speed to C++, and its strict type system makes refactoring and code maintenance significantly cheaper.

Who Has Already Switched to Rust?

• Google — uses Rust in the Android kernel (the "Rust in the Linux kernel" project) and in ChromeOS components. In 2025, the company announced that all new security subsystems are written exclusively in Rust.
• Microsoft — is actively rewriting components of Windows and Azure in Rust. In March 2025, a beta version of the Rust SDK for the Windows kernel was released.
• Amazon Web Services (AWS) — Rust is used for critical services such as Firecracker (micro-VM) and S3. AWS even released its own Rust framework for cloud functions.
• Meta (Facebook) — Rust has become the primary language for developing internal tools, including the source code management system and a new compiler for Hack.
• Dropbox — completely rewrote its file system in Rust, reducing memory consumption by 30%.

What Does This Mean for Developers?

The job market for Rust developers has grown by 280% over the past year. The average salary for a Rust specialist in 2025 exceeds $180,000 in the US and €120,000 in Europe. If you write in Python, C++, or Java — now is the best time to start learning Rust. It perfectly complements Python: you can write fast, safe libraries in Rust and connect them to Python code via PyO3 or maturin.

How Can a Python Developer Get Started with Rust?

• Start small: rewrite one narrow function (parsing, cryptography, working with binary data) from Python to Rust.
• Use tools: install Rust via rustup, then learn maturin — it will automatically create a Python package from Rust code.
• Don't fear the compiler: Rust teaches you to write correct code from the start. Its error messages are the best in the industry.

The trend of 2025 is clear: Rust is ceasing to be the "language of the future" and is becoming the language of the present. Companies are voting for it with their money and the migration of millions of lines of code. Don't miss your chance to ride the wave.
