Go (Golang) and Microservices: From Idea to Production

The book "Go (Golang) and Microservices: From Idea to Production" is a practical guide that will take you through all the stages of creating modern microservice applications in Go. The author, an experienced developer and architect, shares proven patterns, best practices, and real-world cases that will help you avoid common mistakes and build a reliable, scalable system.

What the book is about

The book covers the full lifecycle of a microservice project: from architecture design to production deployment. You will learn how to properly decompose a monolith, organize interaction between services, and ensure fault tolerance and monitoring. Special attention is given to the features of the Go language: goroutines, channels, efficient memory management, and performance.

• Microservice Architecture: decomposition principles, Saga, CQRS, Event Sourcing patterns, protocol selection (REST, gRPC, GraphQL).
• Development in Go: API design, working with databases (PostgreSQL, MongoDB), error handling, logging, and configuration.
• Integration and Data Exchange: synchronous and asynchronous interaction, message queues (RabbitMQ, Kafka), event brokers.
• Containerization and Orchestration: Docker containers, Docker Compose, deployment in Kubernetes, CI/CD pipelines.
• Security: authentication and authorization (JWT, OAuth2), secret management, protection against DDoS and other attacks.
• Monitoring and Debugging: metric collection (Prometheus), tracing (Jaeger), centralized logging (ELK), code profiling.
• Testing: unit tests, integration tests, contract testing (Pact), load testing.

Who this book is for

The book will be useful for:

• Go developers who want to transition from writing monolithic applications to microservice architecture.
• DevOps engineers seeking a deeper understanding of the specifics of deploying and operating Go services.
• Architects looking for proven approaches to designing distributed systems.
• Team leads and technical managers wanting to evaluate Go's capabilities for microservice development.

What you will learn

After reading the book, you will be able to:

• Design microservice architecture considering performance, scalability, and fault tolerance requirements.
• Write efficient and secure microservices in Go using the standard library and popular frameworks.
• Configure interaction between services via REST, gRPC, and asynchronous queues.
• Containerize applications and deploy them in Kubernetes.
• Implement monitoring, logging, and tracing to control system state.
• Conduct microservice testing at all levels.

The book contains numerous code examples, diagrams, and practical exercises. Each chapter concludes with a summary and self-test questions. This is
