Go (Golang) and Microservices: From Idea to Production

The book «Go (Golang) and Microservices» is a comprehensive guide to building modern distributed systems in the Go language. The author, Andrey Volkov, an experienced backend developer and architect, shares proven practices that will help you transition from monolithic architecture to flexible, scalable microservices.

The book starts with the basics: you will understand why Go is ideal for microservice architecture and learn to design loosely coupled, high-performance services. Special attention is given to practical aspects — from choosing interaction protocols to organizing deployment in a production environment.

What you will learn from the book:

• Fundamentals of microservice architecture — decomposition principles, interaction patterns, data management.
• Creating HTTP/REST and gRPC services — routing setup, error handling, middleware.
• Working with databases — PostgreSQL, MongoDB, Redis, data access patterns.
• Inter-service communication — synchronous and asynchronous communications, message queues (RabbitMQ, Kafka).
• Containerization and orchestration — Docker, Docker Compose, deployment in Kubernetes.
• Monitoring and logging — Prometheus, Grafana, OpenTelemetry, centralized log collection.
• CI/CD and testing — unit, integration, e2e tests, build and deployment automation.
• Security — authentication (JWT, OAuth2), TLS, secret management.

Who this book is for:

• Go developers looking to master microservice architecture.
• Backend engineers planning to transition from monoliths to distributed systems.
• Team leads and architects seeking practical recipes for designing reliable services.
• Anyone who wants to learn the modern tool stack (Docker, Kubernetes, gRPC, Prometheus) in the context of Go.

Each chapter contains real code examples ready for use. You will build a complete microservice system, integrate it with external services, and set up a production environment. The book is suitable both for beginners who are confident in Go basics and for experienced developers looking to systematize their knowledge.

«Go (Golang) and Microservices» is not just theory, but a practical guide that will become your desktop reference when creating distributed systems. Start building reliable and scalable microservices today!
