Practical DevOps - Second Edition

By: joakim verona

Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all code workflows from testing environments to production environments. It stresses cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. Practical DevOps begins with a quick refresher on DevOps and continuous delivery and quickly moves on to show you how DevOps affects software architectures. You'll create a sample enterprise Java application that you’'ll continue to work with through the remaining chapters. Following this, you will explore various code storage and build server options. You will then learn how to test your code with a few tools and deploy your test successfully. In addition to this, you will also see how to monitor code for any anomalies and make sure that it runs as expected. Finally, you will discover how to handle logs and keep track of the issues that affect different processes. By the end of the book, you will be familiar with all the tools needed to deploy, integrate, and deliver efficiently with DevOps.

Why do we build code?

Most developers are familiar with the process of building code. When we work in the field of DevOps, however, we might face issues that developers who specialize in programming a particular component type won't necessarily experience.

For the purposes of this book, we define software building as the process of molding code from one form to another. During this process, several things might happen:

  • The compilation of source code to native code or virtual machine bytecode, depending on our production platform.
  • Linting of the code, which involves checking the code for errors and generating code quality measures by means of static code analysis. The term linting originated with a program called lint, which started shipping with early versions of the Unix operating system. The purpose of the program was to find bugs in programs that were syntactically correct...
