Golang Crash Course: Use Golang to build high-performance concurrent cloud-native applications

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.
