C++ and Microservices: A Practical Guide to Development

The book "C++ and Microservices" is a practical guide to designing, developing, and deploying microservice architectures using the C++ language. Unlike popular languages like Go or Java, C++ offers unique advantages: minimal memory consumption, predictable performance, and full control over resources. This book will show you how to leverage these capabilities to build fast and reliable distributed systems.

Who is this book for?

• C++ developers who want to master microservice architecture
• Software architects seeking efficient solutions for high-load systems
• DevOps engineers working with C++ services
• Developers transitioning from monoliths to microservices

What you will learn from the book:

• Fundamentals of microservice architecture and its differences from monolithic applications
• How to organize inter-service communication: REST, gRPC, message queues (RabbitMQ, Kafka)
• Design patterns for C++ microservices: Circuit Breaker, Saga, CQRS, Event Sourcing
• Working with containerization (Docker) and orchestration (Kubernetes) for C++ services
• Testing microservices: unit, integration, contract (Pact)
• Monitoring, logging, and tracing (OpenTelemetry, Prometheus, Grafana)
• Ensuring fault tolerance and scaling
• Microservice security: authentication, authorization, TLS

The book contains numerous practical code examples in C++17/20, ready-to-use templates, and architectural solutions. You will learn to design services that can be independently developed, tested, and deployed.

Book highlights:

• Focus on performance: zero-copy, memory pooling, lock-free structures
• Working with modern libraries: Boost.Asio, gRPC, Crow, drogon
• Examples of real projects: from a simple API gateway to a distributed data processing system
• Coverage of common mistakes and how to avoid them

This book will become an indispensable resource for those who want to build fast, reliable, and scalable microservices in C++. Whether you are starting from scratch or already have experience, you will find valuable knowledge and practical advice here.
