Cloud-Native Applications with Go

Cloud-Native Applications with Go: From REST and gRPC to Docker and Kubernetes

Building modern applications isn't just about writing code-it's about creating systems that can scale, recover, and thrive in production. The challenge is clear: how do you go from a simple Go service on your laptop to a resilient, containerized, and observable application running smoothly in the cloud?

This book delivers the answer. Cloud-Native Applications with Go is a hands-on guide for developers who want to build powerful, production-grade microservices. It brings together the essential building blocks-REST and gRPC APIs, Docker containers, Kubernetes deployments, observability, leak detection, and resilience patterns-and shows you how to use them effectively with Go. Every concept is taught through practical application, so you can confidently take your code from development to deployment.

Inside, you'll gain the skills to:

• Design clean, testable REST and gRPC endpoints that form the backbone of microservices.

• Package and run Go services consistently with Docker, ensuring reliable behavior across environments.

• Deploy and scale your applications on Kubernetes with health checks, autoscaling, and smart service discovery.

• Apply resilience techniques such as circuit breakers, retries, and sidecar patterns to keep your system robust.

• Instrument logs, metrics, and distributed traces with Prometheus and Grafana for end-to-end visibility.

• Catch goroutine leaks and performance bottlenecks before they affect production.

• Build and ship a complete mini e-commerce system as a proof of mastery.

What sets this book apart is its relentless focus on practicality. Every chapter brings you closer to the skills professional Go developers rely on daily-skills that employers and teams expect when running real workloads at scale. The tone is direct, developer-first, and infused with the passion of building software that matters.

If you're ready to stop experimenting and start building production-ready systems, this book is your blueprint. With Cloud-Native Applications with Go, you'll not only write Go code-you'll build applications that can withstand traffic spikes, survive failures, and deliver value reliably.

Your next step is clear: pick up this book and start building Go microservices that are cloud-ready from day one.
