Rust and Microservices: Building Fault-Tolerant Distributed Systems

The book "Rust and Microservices" is a comprehensive practical guide to creating modern, fault-tolerant, and high-performance microservices in the Rust language. Unlike abstract manuals, this book is built around a real end-to-end project — an order management system for an online store, which you will develop from the first line of code to production deployment.

What is this book about?

You will start with the basics: setting up the environment, working with the Cargo package manager, and the Rust type system. Next, you will dive into the asynchronous programming ecosystem — studying the Actix Web framework and the Tokio runtime. Special attention is given to:

• Designing REST APIs and gRPC services using tonic
• Working with PostgreSQL and Redis via sqlx and redis-rs
• Organizing inter-service communication (gRPC, RabbitMQ, Kafka)
• Logging, metrics, and monitoring (tracing, Prometheus)
• Containerization with Docker and orchestration with Docker Compose
• Testing (unit, integration, load) and CI/CD

Who is this book for?

The book is aimed at developers who are already familiar with the basics of programming and want to learn Rust for backend development. You will feel comfortable if:

• You write in Go, Python, or Java and want to switch to Rust
• You already know Rust at a basic level but have not built production systems
• You work with microservice architecture and are looking for a safer and faster alternative to existing solutions

What will you learn?

After reading the book, you will be able to:

• Design and develop microservices from scratch in Rust
• Use asynchronous programming without fear of data races (thanks to the ownership system)
• Integrate services via gRPC and message queues
• Write safe and efficient code that compiles without errors
• Deploy applications in containers and set up monitoring
• Conduct load testing and optimize performance

The book contains over 50 practical examples, ready-to-use code snippets, and two full-fledged microservices in the final section. All source code is available on GitHub and accompanied by detailed comments.

"Rust and Microservices" is not just a textbook, but a reference book for any developer who wants to build reliable and fast distributed systems. Rust provides memory safety guarantees at the compilation level, while the microservice architecture offers flexibility and scalability. Combine them and get the technology stack chosen by industry leaders: Dropbox, Figma, Cloudflare.
