C++ and Microservices: Building High-Load Systems

The book "C++ and Microservices" is a comprehensive practical guide for developers who want to master building microservice architecture using C++. Unlike popular languages like Go or Java, C++ offers unique advantages: low-level memory control, minimal resource consumption, and the highest performance. However, building microservices in C++ requires a special approach — and this book fills all the gaps.

What is the book about?

The author consistently guides the reader from the basics of the microservice approach to industrial deployment. You will learn:

• How to design service boundaries and choose interaction protocols (REST, gRPC, message brokers).
• Features of asynchronous programming in C++ (Boost.Asio, C++20 coroutines) for building non-blocking services.
• Integration with Docker and Kubernetes: creating lightweight images, orchestration, health checks.
• Working with databases in a microservice environment (PostgreSQL, Redis, Saga pattern).
• Writing tests (unit, integration, contract tests) and ensuring fault tolerance (circuit breaker, retries).
• Monitoring and logging: OpenTelemetry, Prometheus, structured logging.

Who is this book for?

• C++ developers who want to transition from monoliths to microservices.
• Software architects looking for efficient solutions for high-load systems.
• DevOps engineers wanting to understand the specifics of C++ when deploying microservices.
• Students and researchers studying modern approaches to distributed computing.

What will you gain after reading?

• Ready-made templates for creating microservices in C++ from scratch.
• Understanding of trade-offs between performance and development complexity.
• Skills in working with real tools: gRPC, Protobuf, CMake, Docker Compose.
• The ability to avoid common mistakes when working with memory and threads in a distributed environment.

The book contains numerous code examples, architectural diagrams, and practical exercises. All examples are tested on modern compilers (GCC, Clang) and are relevant for C++17/20. This is not just theory — you will be able to immediately apply the knowledge gained in your projects.

If you want to build fast, reliable, and scalable systems in C++ — this book will become your reliable assistant.
