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.

The appeal of Cucumber from a DevOps point of view is that it is intended to bring different roles together. Cucumber feature definitions are written in a conversational style that can be achieved without programming skills. The hard data required for test runs is then extracted from the descriptions and used for the tests.

While the intentions are good, there are difficulties in implementing Cucumber that might not immediately be apparent. While the language of the behavior specifications...
