Golang Crash Course: Use Golang to build high-performance concurrent cloud-native applications (English Edition)

Golang, which is created and maintained by Google, is one of the most powerful programming languages used to build cloud-native applications and distributed systems. The simplicity, concurrency model, and efficient runtime of the programming language make it a preferred choice for modern cloud and microservices. The Golang Crash Course is a comprehensive and structured guide that covers all the necessary concepts to become a Golang expert, including concurrency, microservices architecture, and scalable API development. The book begins with the basics of Golang’s syntax, data structures, functions, and error handling. It then explores Golang’s powerful concurrency model using goroutines and channels, which helps readers design highly efficient parallel programs. In the final section, readers will learn how to build real-world microservices, develop REST APIs, secure services, deploy applications using Docker and Kubernetes, and finally manage data in distributed systems. By the end of this book, readers will be able to design, build, secure, and deploy production-ready Golang applications. They will gain practical experience in building scalable backend services and cloud-native systems using modern development tools and best practices.What you will learn● Understand Golang’s syntax, types, and language fundamentals.● Building efficient programs using goroutines and channels.● Designing scalable REST APIs and microservices in Golang.● Organizing Golang applications using packages and modules.● Securing services with authentication, TLS, and RBAC.● Deploying Golang applications using Docker and Kubernetes.Who this book is forThis book is designed for engineering students, software developers, backend engineers, cloud engineers, and DevOps professionals who want to learn Golang for building modern and cloud-native distributed applications. It is suitable for beginners to intermediate developers who have basic programming knowledge in any languages like Java, Python, C, or C++.Table of Contents1. Introduction to Go2.
