Practical DevOps Second Edition

▶Book Description
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.

▶What this book covers
⦁ Chapter 1, Introducing DevOps and Continuous Delivery, deals with the background of DevOps and sets the scene for how DevOps fits in the wider world of agile systems development.

⦁ Chapter 2, A View from Orbit, will help you understand how all the systems we use in DevOps fit together, forming a larger whole.

⦁ Chapter 3, How DevOps Affects Architecture, describes the aspects of software architecture and what they mean to us while working with our DevOps glasses on.

⦁ Chapter 4, Everything is Code, explains how everything is coded and you need somewhere to store it. The organization's source code management system is that place.

⦁ Chapter 5, Building the Code, explains how you need systems to build your code. They are described in this chapter.

⦁ Chapter 6, Testing the Code, shows you that if you are going to release your code early and often, you must be confident of its quality. Therefore, you need automated regression testing.

⦁ Chapter 7, Deploying the Code, shows how, when the code has been built and tested, you need to deploy it on your servers so that your customers can use the newly developed features.

⦁ Chapter 8, Monitoring the Code, covers how the code is safely deployed on your servers with the deployment solution of your choice; you need to watch over it to make sure it's running properly.

⦁ Chapter 9, Issue Tracking, looks at systems used to handle development workflows within an organization, such as issue tracking software. Such systems are an important aid when implementing agile processes.

⦁ Chapter 10, The Internet of Things and DevOps, describes how DevOps can assist us in the emerging field of Internet of Things.
