Serverless Architectures with Kubernetes

By: Onur Yılmaz, Sathsara Sarathchandra

Overview of this book

Kubernetes has established itself as the standard platform for container management, orchestration, and deployment. By learning Kubernetes, you’ll be able to design your own serverless architecture by implementing the function-as-a-service (FaaS) model. After an accelerated, hands-on overview of the serverless architecture and various Kubernetes concepts, you’ll cover a wide range of real-world development challenges faced by real-world developers, and explore various techniques to overcome them. You’ll learn how to create production-ready Kubernetes clusters and run serverless applications on them. You'll see how Kubernetes platforms and serverless frameworks such as Kubeless, Apache OpenWhisk and OpenFaaS provide the tooling to help you develop serverless applications on Kubernetes. You'll also learn ways to select the appropriate framework for your upcoming project. By the end of this book, you’ll have the skills and confidence to design your own serverless applications using the power and flexibility of Kubernetes.

Kubernetes Design and Components

Kubernetes, which is also known as k8s, is a platform for managing containers. It is a complex system focused on the complete life cycle of containers, including configuration, installation, health checking, troubleshooting, and scaling. With Kubernetes, it is possible to run microservices in a scalable, flexible, and reliable way. Let's assume you are a DevOps engineer at a fin-tech company, focusing on online banking for your customers.

You can configure and install the complete backend and frontend of an online bank application to Kubernetes in a secure and cloud-native way. With the Kubernetes controllers, you can manually or automatically scale your services up and down to match customer demand. Also, you can check the logs, perform health checks on each service, and even SSH into the containers of your applications.

In this section, we will focus on how Kubernetes is designed and how its components work in harmony.
