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.

For the time being, it is enough to understand that when we work with DevOps, we work with large and complex processes in a large and complex context.

An example of a CD pipeline in a large organization is introduced in the following diagram:

While the basic outline of this diagram holds true surprisingly often, regardless of the organization, there are, of course, differences, depending on the size of the organization and the complexity of the products that are being developed.

The early parts of the chain, that is, the developer environments and the CI environment, are normally very similar...
