In this chapter, we have learned what cloud-native apps or solutions are, the difference between cloud-native and cloud-ready solutions, the benefits of building cloud-native solutions, the different pillars of cloud-native apps (including microservices, containers, CI/CD, and automation), and the Twelve-Factor App methodology.
