Summary

In this chapter, we have seen the main concepts pertaining to cloud-native architectures. Starting with the goals and benefits, we have seen the concept of PaaS and Kubernetes, which is currently a widely used engine for PaaS solutions. An interesting excursus involved the twelve-factor applications, and we also discussed how some of those concepts more or less map to Kubernetes concepts.

We then moved on to the well-known issues in cloud-native applications, including fault tolerance, transactionality, and orchestration. Lastly, we touched on the further evolution of microservices architectures, that is, miniservices and serverless.

With these concepts in mind, you should be able to understand the advantages of a cloud-native application and apply the basic concepts in order to design and implement cloud-native architectures.

Then, we moved on to look at a couple of methodologies for application modernization, and when and why these kinds of projects are worth undertaking...
