Rust and Microservices: Building Reliable Distributed Systems

Microservice architecture has become the standard for building modern high-load applications. And Rust is the language that guarantees safe memory management, high performance, and predictable behavior under load. The book "Rust and Microservices" connects these two worlds, offering a practical approach to developing distributed systems.

This is not another syntax reference. You will dive into real-world scenarios: from designing service boundaries to deploying to production. Each chapter contains ready-made code examples that can be adapted to your own tasks.

What you will learn:

• How to design microservices considering Rust's features (ownership, lifetimes, Send + Sync)
• Working with the Tokio async runtime and the Actix-web framework
• Service interaction via gRPC, RabbitMQ, and HTTP/REST
• Error handling, logging, and monitoring of distributed systems
• Testing: unit, integration, end-to-end (E2E), and property-based testing
• Containerization (Docker, Docker Compose) and orchestration (Kubernetes basics)

Who this book is for:

• Backend developers familiar with Rust at a basic level (or with another language but ready to learn)
• DevOps engineers who want to understand how microservices in Rust work from the inside
• Architects looking for a tool to build performant and secure systems

Why this book:

Rust is not a trendy fad, but a pragmatic choice for services where the cost of an error is high. You will learn how to avoid typical problems: data races, memory leaks, inefficient I/O operations. The author shares experience gained from developing fintech projects and highload systems.

In the book you will find the full development cycle: from the first line of code to monitoring in production. All examples are available in the repository and tested with current versions of Rust (edition 2024+).

If you want to build systems that run fast, don't crash under load, and scale easily — this book is for you.
