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.

2. Introduction to Serverless in the Cloud

Introduction to Kubernetes

In the previous chapter, we studied serverless frameworks, created serverless applications using these frameworks, and deployed these applications to the major cloud providers.

As we have seen in the previous chapters, Kubernetes and serverless architectures started to gain traction at the same time in the industry. Kubernetes got a high level of adoption and became the de facto container management system with its design principles based on scalability, high availability, and portability. For serverless applications, Kubernetes provides two essential benefits: removal of vendor lock-in and reuse of services.

Kubernetes creates an infrastructure layer of abstraction to remove vendor lock-in. Vendor lock-in is a situation where transition from one service provider to another is very difficult or even infeasible. In the previous chapter, we studied how serverless frameworks make it easy to develop cloud-agnostic serverless applications. Let's assume...
