Architecture of Go (Golang) Applications

The book "Architecture of Go (Golang) Applications" is a comprehensive guide to designing and building reliable, scalable, and high-performance systems in Go. It is intended for developers who already have basic knowledge of Go and want to move to the next level — learning how to properly structure the architecture of their projects.

What is this book about?

The book covers in detail all key aspects of Go application architecture:

• Project Structure — proper organization of code, packages, and modules to ensure readability, testability, and scalability.
• Design Patterns — implementation of classic (Factory, Singleton, Strategy) and Go-specific patterns (Pipeline, Fan-In/Fan-Out, Context).
• Working with Goroutines and Channels — effective use of concurrency, state management, preventing leaks and deadlocks.
• Microservice Architecture — designing distributed systems, interaction via gRPC/REST, data and transaction management.
• Error Handling and Logging — error handling strategies, centralized logging, monitoring, and alerting.
• Testing — unit tests, integration tests, mocks, testing concurrent code.

Who is this book for?

This book will be useful for:

• Backend developers transitioning to Go from other languages (Python, Java, C++).
• Intermediate Go developers looking to deepen their knowledge of architecture.
• Tech leads and architects designing high-load systems.
• Students and interns learning industrial Go development.

What will the reader learn?

After reading this book, you will be able to:

• Design modular and easily maintainable applications.
• Effectively use concurrency without common mistakes.
• Select and implement appropriate patterns for specific tasks.
• Build microservice architectures with high fault tolerance.
• Write code that is easy to test, refactor, and scale.

The book contains numerous practical examples, diagrams, and ready-made code templates that can be immediately applied in real projects. This is not just theory — it is a tool for daily work.
