Summary

In this chapter, we introduced the CD process, including the idea behind it, its prerequisites, and the tools that will be used throughout this book. The key takeaway from this chapter is that the delivery process that's currently used in most companies has significant shortcomings and can be improved using modern automation tools. The CD approach provides several benefits, of which the most significant ones are fast delivery, a fast feedback cycle, and low-risk releases. The CD pipeline consists of three stages: CI, automated acceptance testing, and configuration management. Introducing CD usually requires the organization to change its culture and structure. The most important tools in the context of CD are Docker, Jenkins, and Ansible.

In the next chapter, we'll introduce Docker and show you how to build a dockerized application.
