Hands-On Software Engineering with Golang

By: Achilleas Anagnostopoulos

Overview of this book

Over the last few years, Go has become one of the favorite languages for building scalable and distributed systems. Its opinionated design and built-in concurrency features make it easy for engineers to author code that efficiently utilizes all available CPU cores. This Golang book distills industry best practices for writing lean Go code that is easy to test and maintain, and helps you to explore its practical implementation by creating a multi-tier application called Links ‘R’ Us from scratch. You’ll be guided through all the steps involved in designing, implementing, testing, deploying, and scaling an application. Starting with a monolithic architecture, you’ll iteratively transform the project into a service-oriented architecture (SOA) that supports the efficient out-of-core processing of large link graphs. You’ll learn about various cutting-edge and advanced software engineering techniques such as building extensible data processing pipelines, designing APIs using gRPC, and running distributed graph processing algorithms at scale. Finally, you’ll learn how to compile and package your Go services using Docker and automate their deployment to a Kubernetes cluster. By the end of this book, you’ll know how to think like a professional software developer or engineer and write lean and efficient Go code.

A list of software development models that all engineers should know

The software engineering definition from the previous section alludes to the fact that software engineering is a complicated, multi-stage process. In an attempt to provide a formal description of these stages, academia has put forward the concept of the SDLC.

The SDLC is a systematic process for building high-quality software that matches the expectations of the end user or customer while ensuring that the project's cost stays within a reasonable bound.

Over the years, there has been an abundance of alternative model proposals for facilitating software development. The following diagram is a timeline illustrating the years when some of the most popular SDLC models were introduced:
