What this book covers

Chapter 1, DevOps Concepts and Assessment Framework, contains details on how to get a quick understanding of DevOps from 10,000 feet and how to prepare for changing a culture. It provides the base on which to build the foundation of the DevOps concepts by discussing what our goals are, as well as getting buy-in from organization management.

Chapter 2, Continuous Integration, explains how to install a Jenkins continuous integration server and perform various tasks related to compilation, unit test execution, code analysis, and creating a package file. This chapter also covers continuous integration using the Microsoft stack. The goal here is to gain as much information as you can about continuous integration as it is a base for the rest of the automation.

Chapter 3, Containers, explains how to use containers for a development or QA environment for better resource utilization. It contains details on how to create a Tomcat container so that we can deploy the application in it.

Chapter 4, Cloud Computing and Configuration Management, focuses on creating and configuring the environment for application deployment in cloud. It will cover the use of the Infrastructure as a Service and configuration management tool, Chef, to create a platform so that we can deploy an application later in the book using automation.

Chapter 5, Continuous Delivery, explains how to deploy a web application when the platform is ready in different ways. This will involve platforms such as AWS and Microsoft Azure Iaas, and PaaS offerings such as AWS Elastic Beanstalk and Microsoft Azure App Services. We will also cover script-based deployment and Jenkins' plugin-based deployment.

Chapter 6, Automated Testing (Functional and Load Testing), explains the various types of testing that can be carried out after deploying the application in non-production environments. It covers how to utilize automated testing techniques to enhance the quality of an application, such as functional testing and load testing using open source tools.

Chapter 7, Orchestration — End-to-End Automation, contains various ways to automate application life cycle management using orchestration. The build pipeline is utilized to orchestrate continuous integration, continuous delivery, and continuous testing. build and release definitions are configured in a way to form a pipeline, so end-to-end automation with proper approval-based mechanism is achieved.

Chapter 8, Security and Monitoring, speaks about security based on roles with only specific stakeholders, so they can manage configuration and builds. We will explore various tools to automate application life cycle management, monitoring, as well as notifications of the outcome based on success and failure, so the stakeholders can take the necessary steps to fix it.
