In the last ten years, Rust grew from an auspicious experiment into one of the most respected technologies for creating fast, safe, and scalable software. Driven by memory safety guarantees, zero-cost abstractions, and a fearless concurrency model, Rust found favor in engineering teams whose work required high performance without sacrifice of safety.
Now, Rust is applied in mission-critical infrastructure of leading companies operating in cloud providers, fin-tech innovators, blockchain projects, and tech giants. Due to the growing interest in performance-oriented and secure software, an increasing number of companies want to partner with a Rust development company like Yalantis to scale up their language adoption and build next-generation solutions.
In this post, learn what the top companies using Rust are, why the trend is occurring, and best practices for helping engineering teams adopt Rust.
Why Rust is the number one choice for most modern engineering teams
Before we get into the companies adopting Rust, it’s useful to understand why the language has seen this explosion of popularity. First and foremost, Rust offers the following key advantages:
1. Memory Safety Without Garbage Collection
Without using a garbage collector, Rust automatically removes whole classes of bugs like null pointer dereferences and data races. This overall effect, in turn, makes Rust particularly well-suited for building systems software and performance-critical components.
2. High-performance, comparable to C and C++
Rust compiles to highly optimized machine code. Because of this, it often outperforms languages that incur runtime overhead.
3. Fearless Concurrency
Rust guarantees thread-safety at compile-time through ownership. Because of this, it’s simpler to write parallel applications.
4. Strong Developer Experience
Along with Rust itself, it includes Cargo, the package manager; modern syntax; and great documentation. All of these factors put together make the language powerful yet a delight to work with.
5. Growing Ecosystem and Community
Rust consistently rates as a top most-loved programming language in various rankings, and the Rust ecosystem grows every year.
Top Companies That Use Rust to Build High-Performance Solutions
Some of the most prominent companies using Rust to solve real-world engineering problems include the following:
1. Mozilla – The Birthplace of Rust
Rust was developed by Mozilla and uses the language extensively internally in a variety of its systems. Probably the best-known of these is the Servo browser engine, which is designed to make the most of parallelism and memory safety. Most parts of Firefox use Rust, too, for added security and performance enhancement.
Why Rust Works for Mozilla
- Eliminates memory vulnerabilities
- Enables safe concurrency in browser components
- It improves low-level performance in a system.
2. Amazon Web Services (AWS)
The result has been that AWS has become one of the most robust adopters of Rust. Key projects like Firecracker-the micro-VM technology powering both AWS Lambda and AWS Fargate-are written in Rust. Firecracker is designed to provide highly secure, lightweight virtualization, and Rust made high isolation with minimal overhead possible.
Why AWS chose Rust
- Strong Guarantees for Secure Sandboxing
- Ultra-high performance for micro-virtualization
- Offering low latency and efficient usage of resources.
3. Microsoft
Microsoft is using Rust to decrease the number of memory-related bugs in key components of Windows. Microsoft researches Rust for projects dealing with cloud infrastructure, device drivers, and security-sensitive layers of their operating systems.
Reasons Rust Is Valuable to Microsoft
- Reduces core system component vulnerabilities
- Assist in migrating legacy C/C++ code.
- Improves long-term maintainability
4. Google
Google’s engineering teams make use of Rust in a variety of projects, most visibly inside the Android Open Source Project. Google uses Rust to contribute to memory safety in the low-level components of Android and has advocated its use when building new system libraries.
What is appealing to Google about Rust?
- Memory-safe by design
- Ideal for the security needs of Android.
- Strong compile-time guarantees
5. Dropbox
Dropbox started rewriting performance-critical infrastructure in Rust. Rust powers the backend that stores and keeps synchronized large amounts of data.
What Dropbox Gains from Rust
- Faster, more predictable performance
- Improvement of memory control
- Efficient, safe concurrency for high workloads
6. Discord
Discord famously ported pieces of its backend from Go to Rust to handle extreme concurrency. Today, Rust powers a system that handles billions of real-time messages per day.
Why Discord Migrated to Rust
- High throughputs even under extreme stress
- Reduced latency for real-time applications
- Full control of the usage of the CPU and memory
7. Cloudflare
Cloudflare uses Rust throughout their edge computing network for security and efficiency. They have rewritten several key pieces of their code in Rust as part of the effort to minimize vulnerabilities.
Advantages for Cloudflare
- Improved security for Internet-scale services
- High performance on distributed edge servers
- Improved productivity for developers
8. Blockchain and Web3 companies
Rust serves as the perfect backbone for projects like Solana, Polkadot, and NEAR. For blockchain systems, performance, security, and concurrency are needed; Rust fits the bill perfectly.
Why Rust Dominates Web3 Development
- Safe, predictable execution of smart contracts
- High throughput, low latency
- Easier auditing compared to C++.
Why clients choose Yalantis for Rust development:
Though powerful, Rust has a steep learning curve. Hence, companies often outsource their work to other firms like Yalantis so that the job would be completed even faster.
How Yalantis Supports Rust Adoption
- End-to-End Rust Development Services: At Yalantis, we build scalable, secure, and performance-oriented solutions based on the latest Rust technologies.
- System-Level Engineering Competencies: The engineers in the company design high-performance software for cloud infrastructure, IoT, FinTech, and Web3.
- Modern Architectural Practices: They adopt microservices, asynchronous programming, and safe concurrency patterns tailored for each project.
- Code Quality, Security, and Maintainability: Yalantis focuses on clear coding standards, secure practices, and long-term maintainability-all strong sides which are aligned with Rust.
- Consulting for Engineering Teams: They help organizations embrace Rust more efficiently, modernize legacy systems, and build solutions from scratch.
Finally, cooperation with a dedicated Rust development company like Yalantis allows organizations to avoid common pitfalls and leverage all the possibilities this language provides.
Best Practices for Engineering Teams Adopting Rust
Here are the ways a company can successfully introduce Rust into its technology stack:
1. Start with Performance-Critical Components
Rewrite high-risk or slow components in Rust instead of rewriting whole platforms.
2. Leverage Rust’s Asynchronous Ecosystem
Frameworks like Tokio and Actix provide high-performance async runtimes.
3. Early Adopt Rust’s Ownership
Model Take time to understand ownership, borrowing, and lifetimes. They are the cornerstone of Rust’s safety.
4. Utilize Cargo’s Ecosystem
Cargo makes dependency management, testing, and versioning straightforward.
5. Continuous Integration and Automated Testing
Built-in testing in Rust makes the CI pipelines more efficient.
Conclusion
Rust is not a niche within programming anymore, but it’s a cornerstone to modern high-performance engineering. AWS, Google, Microsoft, Dropbox, and Discord each trust Rust to craft secure, scalable, and efficient systems. From cloud computing to real-time messaging to blockchain, Rust has shown it can outperform legacy languages with superior safety. In the light of this, and with more organizations realizing its potential, partnering with a leading Rust development company such as Yalantis will be indispensable when it comes to building long-lasting, secure, and high-performance software. With expert guidance on how to approach it in a structured manner, businesses can drive innovation and develop powerful solutions for the future.
