Becoming KCNA Certified

By: Dmitry Galkin

Overview of this book

The job market related to the cloud and cloud-native technologies is both growing and becoming increasingly competitive, making certifications like KCNA a great way to stand out from the crowd and learn about the latest advancements in cloud technologies. Becoming KCNA Certified doesn't just give you the practical skills needed to deploy and connect applications in Kubernetes, but it also prepares you to pass the Kubernetes and Cloud Native Associate (KCNA) exam on your first attempt. The book starts by introducing you to cloud-native computing, containers, and Kubernetes through practical examples, allowing you to test the theory out for yourself. You'll learn how to configure and provide storage for your Kubernetes-managed applications and explore the principles of modern cloud-native architecture and application delivery, giving you a well-rounded view of the subject. Once you've been through the theoretical and practical aspects of the book, you'll get the chance to test what you’ve learnt with two mock exams, with explanations of the answers, so you'll be well-prepared to appear for the KCNA exam. By the end of this Kubernetes book, you'll have everything you need to pass the KCNA exam and forge a career in Kubernetes and cloud-native computing.

Cloud Native architectures

In the first two chapters, we’ve already covered the definition of Cloud Native. Let’s check it one more time for a quick recap.

Cloud Native

This is an approach to building and running applications on modern, dynamic infrastructures such as clouds. It emphasizes application workloads with high resiliency, scalability, a high degree of automation, ease of management, and observability.

Yet, despite the presence of the word cloud, a Cloud Native application is not strictly required to run in the cloud. It’s an approach that can be followed when building and running applications also on-premises. And yes—you can also build resilient, scalable, highly automated applications on-premises that are Cloud Native, albeit not running in the cloud.

It is important to understand that simply picking a well-known public cloud provider and building on top of its service offerings (whether IaaS, PaaS, SaaS, or FaaS) does not mean your...
