Overview of this book

DevOps is a practical field that focuses on delivering business value as efficiently as possible. DevOps encompasses all the flows from code through testing environments to production environments. It stresses the cooperation between different roles, and how they can work together more closely, as the roots of the word imply—Development and Operations. After a quick refresher to DevOps and continuous delivery, we quickly move on to looking at how DevOps affects architecture. You'll create a sample enterprise Java application that you’ll continue to work with through the remaining chapters. Following this, we explore various code storage and build server options. You will then learn how to perform code testing with a few tools and deploy your test successfully. Next, you will learn how to monitor code for any anomalies and make sure it’s running properly. Finally, you will discover how to handle logs and keep track of the issues that affect processes

Continuous Delivery


After the Continuous Integration steps have completed successfully, you have shiny new artifacts that are ready to be deployed to servers. Usually, these are test environments set up to behave like production servers.

We will discuss deployment system alternatives later in the book.

Often, the last thing a build server does is to deploy the final artifacts from the successful build to an artifact repository. From there, the deployment servers take over the responsibility of deploying them to the application servers. In the Java world, the Nexus repository manager is fairly common. It has support for other formats besides the Java formats, such as JavaScript artifacts and Yum channels for RPMs. Nexus also supports the Docker Registry API now.

Using Nexus for RPM distributions is just one option. You can build Yum channels with a shell script fairly easily.
