Go (Golang) and Microservices: From Idea to Production

Modern software development is increasingly built on a microservice architecture. The Go language (Golang), thanks to its performance, simplicity, and built-in concurrency support, has become one of the best tools for creating microservices. The book "Go (Golang) and Microservices: From Idea to Production" is a practical guide that will take you through the entire journey of building a microservice application in Go.

What is this book about?

The book covers the full development cycle of microservices: from architecture design to deployment in a production environment. You will learn:

• How to properly decompose a monolithic application into microservices
• Principles for building a reliable and scalable architecture in Go
• Working with REST API and gRPC for inter-service communication
• Managing state and databases in a distributed system
• Containerizing microservices with Docker and orchestrating them in Kubernetes
• Testing microservices: unit, integration, e2e
• Monitoring, logging, and error handling in production

Who is this book for?

The book is intended for:

• Go developers looking to master microservice architecture
• Backend engineers transitioning from other languages (Python, Java, C#)
• Software architects seeking practical examples in Go
• DevOps engineers working with microservices and containerization

A basic knowledge of Go syntax and a general understanding of web development are sufficient for reading.

What will you learn?

After reading the book, you will be able to:

• Design a microservice architecture considering the domain model
• Create efficient REST and gRPC services in Go
• Configure inter-service communication (synchronous and asynchronous)
• Work with message queues (RabbitMQ, Kafka)
• Containerize applications and deploy them in Kubernetes
• Write tests and ensure the reliability of a distributed system
• Apply patterns such as Circuit Breaker, Retry, Bulkhead

Why should you read it?

The book is written by a practicing developer with many years of experience building microservices in Go. All code examples are available in the repository, and each chapter includes exercises to reinforce the material. This is not just theory — you will get ready-made solutions that you can apply in your own projects.

Format: The book is available in PDF and EPUB. Example code is hosted on GitHub.

Note: The book covers current versions of Go (1.22+) and popular libraries (gin, echo, protobuf, testify, etc.).
