Go Microservices: Designing REST APIs with SQL, NoSQL, and Clean Architecture

Transitioning from basic Go syntax to building scalable, production-grade microservices requires a solid grasp of architectural patterns and database integrations. This text-based course guides you through the process of designing robust REST APIs using Go. You will transition from writing simple scripts to architecting clean, maintainable microservices. By reading through structured explanations and analyzing clear code snippets, you will learn how to organize Go packages, handle database persistence across different storage engines, and apply architectural patterns like MVC and Hexagonal Architecture. What you'll learn: - Understand the fundamentals of REST API design and application packaging in Go. - Apply clean architecture principles, including MVC and Hexagonal (Ports and Adapters) design patterns. - Configure and integrate diverse data stores such as SQL databases, Cassandra, and Elasticsearch. - Implement the Data Access Object (DAO) pattern to decouple business logic from storage layers. - Practice testing and mocking database dependencies to ensure code reliability. - Design concurrent microservices using goroutines for performance and structured logging for observability. The course begins with foundational concepts of microservice architecture and Go package structure before moving into database integrations and architectural patterns. You will read detailed code walk-throughs and complete written exercises to reinforce your learning. This course is designed for beginner to intermediate Go developers who want to learn software architecture and database integration. No advanced microservices experience is required.
