Production Go

Build modern, production-ready web services in Go

About the Book

With its focus on simplicity and getting things done, Go is a great language for developing performant, robust and maintainable applications. Production Go first teaches the basics of the Go language, then discusses how to bring an application from development to real users. The authors draw from years of experience running high-volume real-world Go applications to explain the tricks behind making—and keeping—Go applications performant, robust and maintainable.
