Network Programming with Go
Dive into key topics in network architecture and Go, such as data serialization, application level protocols, character sets and encodings. This book covers network architecture and gives an overview of the Go language as a primer, covering the latest Go release. Beyond the fundamentals, Network Programming with Go covers key networking and security issues such as HTTP and HTTPS, templates, remote procedure call (RPC), web sockets including HTML5 web sockets, and more. Additionally, author Jan Newmarch guides you in building and connecting to a complete web server based on Go. This book can serve as both as an essential learning guide and reference on Go networking. What You Will Learn Master network programming with Go Carry out data serialization Use application-level protocols Manage character sets andencodings Deal with HTTP(S) Build a complete Go-based web server Work with RPC, web sockets, and more Who This Book Is For Experienced Go programmers and other programmers with some experience with the Go language.
Network Programming with Go
Network Programming with Go teaches you how to write clean, secure network software with the programming language designed to make it seem easy. Build simple, reliable, network software Combining the best parts of many other programming languages, Go is fast, scalable, and designed for high-performance networking and multiprocessing. In other words, it’s perfect for network programming. Network Programming with Go will help you leverage Go to write secure, readable, production-ready network code. In the early chapters, you’ll learn the basics of networking and traffic routing. Then you’ll put that knowledge to use as the book guides you through writing programs that communicate using TCP, UDP, and Unix sockets to ensure reliable data transmission. As you progress, you’ll explore higher-level network protocols like HTTP and HTTP/2 and build applications that securely interact with servers, clients, and APIs over a network using TLS. You'll also learn: Internet Protocol basics, such as the structure of IPv4 and IPv6, multicasting, DNS, and network address translation Methods of ensuring reliability in socket-level communications Ways to use handlers, middleware, and multiplexers to build capable HTTP applications with minimal code Tools for incorporating authentication and encryption into your applications using TLS Methods to serialize data for storage or transmission in Go-friendly formats like JSON, Gob, XML, and protocol buffers Ways of instrumenting your code to provide metrics about requests, errors, and more Approaches for setting up your application to run in the cloud (and reasons why you might want to) Network Programming with Go is all you’ll need to take advantage of Go’s built-in concurrency, rapid compiling, and rich standard library. Covers Go 1.15 (Backward compatible with Go 1.12 and higher)
Learning Go with Networking
DESCRIPTION Golang has emerged as a powerful language for networking, known for its efficiency and concurrency, making it ideal for building resilient and scalable network applications. This book is designed to equip networking professionals with the Golang skills needed to navigate this dynamic landscape, providing a practical guide from fundamental concepts to advanced network programming. This book systematically guides you through Golang's core features, including concurrency, generics, and error handling, before diving into essential networking principles like IP, TCP, and UDP. You will learn to develop applications, design synchronous and asynchronous APIs (with a focus on Ponzu and Keycloak), and effectively handle data using formats like JSON and XML, along with stream processing with AMQP, Kafka, and MQTT. The book explores Golang network packages for protocols such as ARP, FTP, DNS, and raw sockets. It also emphasizes performance optimization, covering I/O, caching, and database techniques, and automation strategies, including device, network, and cloud deployment, along with Cisco DevNet. Security is thoroughly addressed, covering authentication, cryptography (SSL/TLS, asymmetric/symmetric), certificate handling, and OWASP Top 10 vulnerabilities, and the book concludes with an exploration of network penetration testing techniques. By the end of this book, readers will gain a solid foundation in Golang and its application to networking, enabling them to build efficient, secure, and automated network solutions and understand the security landscape, from defensive best practices to offensive techniques. WHAT YOU WILL LEARN ● Build scalable backend services using Go and its libraries. ● Understand TCP/UDP networking through real Go-based examples. ● Develop secure APIs with authentication and token handling. ● Automate infrastructure tasks using Golang and DevNet. ● Identify and fix OWASP Top 10 vulnerabilities in Go. ● Perform ethical hacking in a controlled lab environment. ● Optimize Go applications using profiling and performance tools. ● Handle data formats like JSON, XML, and Base64 effectively. WHO THIS BOOK IS FOR This book is for software developers, DevOps engineers, backend architects, and cybersecurity professionals who want to build scalable, secure, and efficient systems using Golang. It is ideal for anyone working in infrastructure, automation, or cloud-native development looking to sharpen their development skills in Golang with respect to network programming.
