- The purpose of software versioning is twofold. First, it allows software engineers to validate whether an external dependency can be safely upgraded without the risk of introducing issues to production systems. Secondly, being able to explicitly reference required software dependencies via their versions is a prerequisite for implementing the concept of repeatable builds.
- A semantic version is a string that satisfies the following format: MAJOR.MINOR.PATCH:
- The major component is incremented when a breaking change is introduced to the software
- The minor component is incremented when new functionality is introduced to the software in a backward-compatible way
- The patch version is incremented when a backward-compatible fix is applied to the code
- In the first case, we would increment the minor version as the new API does not break backward compatibility. In the second...

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.
