Building Distributed Systems with Go and NATS

Learn to architect, implement, and scale robust distributed systems. This practical guide emphasizes real-world applications of domain-driven design, hexagonal architecture, and reactive systems, all within the context of the Go programming language and the NATS messaging system.

The book begins with foundational concepts and gradually progresses to advanced architectural patterns. You will first explore synchronous and asynchronous communication mechanisms before learning to design and implement individual services that are resilient, scalable, and responsive. From there, the focus expands to broader system architecture. You will learn to create software aligned with real-world business processes using domain-driven design. Finally, you ll explore hexagonal architecture and reactive systems to learn how to design modular, resilient systems capable of handling concurrency and asynchronous processing efficiently.

Today, the adoption of distributed systems is accelerating, necessitating a nuanced understanding of distributed architecture principles. Through clear methodologies, architectural discussions, practical examples, and real-world scenarios, you will be ready to build distributed systems with confidence.

What You Will Learn:

• Understand distributed systems basics, including communication protocols like req/rep, push/pull, and pub/sub.
• Grasp microservice internals such as service discovery, load balancing, and fault tolerance.
• Apply the concepts of domain-driven design, hexagonal architecture, and reactive systems practically.
• Build robust distributed systems using Go and NATS messaging system using real-world examples.
• Explore the architecture of interconnected components to design modular, maintainable systems.
