Summary

In this chapter, we first described conventional software development methods and discovered their boundaries. Precisely, we explained how conventional methods failed to encourage collaboration between development and operations, ultimately resulting in failures. Then, we discussed the motivation for the DevOps cultural shift.

We then progressed to introduce the DevOps toolchain in detail. Each stage of the toolchain was explained, firstly as a black box, and later, cloud-native modern implementations were discussed. We mentioned that each stage of the DevOps toolchain aims to increase collaboration and create a successful software project. Through the chain, a DevOps blog was planned, created, and released. At the end of the chapter, this DevOps blog was automated with a CI/CD pipeline within an activity.

The DevOps toolchain and DevOps practices discussed in this chapter will be revisited in later chapters to be implemented inside Kubernetes. In the next chapter, we will be describing the fundamentals of cloud-native technologies, microservices, and containers. These concepts are essential, since they are the building blocks of container orchestration and Kubernetes.
