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 Setup

Kubernetes is a flexible system that can be installed on various platforms from Raspberry Pi to high-end servers in data centers. Each platform comes with its advantages and disadvantages in terms of service quality, monitoring, security, and operations. Kubernetes manages applications as containers and creates an abstraction layer on the infrastructure. Let's imagine that you set up Kubernetes on the three old servers in your basement and then install the Proof of Concept (PoC) of your new project. When the project becomes successful, you want to scale your application and move to a cloud provider such as Amazon Web Services (AWS). Since your application is designed to run on Kubernetes and does not depend on the infrastructure, porting to another Kubernetes installation is straightforward.

In the previous chapter, we studied the development environment setup using minikube, the official method of Kubernetes. In this section, production-level Kubernetes platforms...
