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.

Since Munin graphs statistics over time, you can see resource allocation trends, which can help you find problems before they get serious. There are several other applications like Munin that create graphs; however, like Nagios, Munin is a good starting point.

It is designed to be easy to use and set up. The out-of-the-box experience gives you many graphs with little work.

In the legends of the Norse, Hugin and Munin were two pitch-black ravens. They tirelessly flew around the world of Midgard and collected information. After their journeys far and wide, they returned to the god king Odin to sit on his shoulders and tell him all about their experiences.

While Nagios...
