Summary

This chapter was the introduction to DevOps for architects. We learned that the enterprise architecture sets the architecture principles for the entire enterprise by using the TOGAF methodology. The business goals are defined at the enterprise level. DevOps projects and teams are concerned with IT delivery and fulfilling the business' demands by building, deploying, and running IT systems.

DevOps needs to adhere to the business goals and, therefore, with the enterprise architecture. Yet, DevOps features a specific architecture that enables CI/CD in IT systems. Because of this, we learned about the six DevOps principles and how these are applied to a reference model in which the enterprise still has full control of the products, but multidisciplinary teams can work autonomously on them.

Next, we looked at the different DevOps components and KPIs to measure the outcomes of DevOps projects. The key takeaway from this is that every project needs to add to a better user experience and thus add business value. Due to this, we briefly studied the VOICE model.

In the next chapter, we will learn more about automation, collaboration, and integration by designing CI/CD pipelines.
