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.

Introduction to OpenWhisk

Until now in this book, we have learned about the Kubeless framework, which is an open source Kubernetes-native serverless framework. We discussed the Kubeless architecture, and created and worked with the Kubeless functions and triggers. In this chapter, we shall be learning about OpenWhisk, which is another open source serverless framework that can be deployed on top of Kubernetes.

OpenWhisk is an open source serverless framework that is part of the Apache Software Foundation. This was originally developed at IBM with the project code name of Whisk, and later branded as OpenWhisk once the source code was open sourced. Apache OpenWhisk supports many programming languages, including Ballerina, Go, Java, JavaScript, PHP, Python, Ruby, Swift, and .NET Core. It allows us to invoke functions written in these programming languages in response to events. OpenWhisk supports many deployment options, such as on-premises and cloud infrastructure.
