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


In the previous chapter, the architectural evolution of traditional architectures to serverless designs was discussed. In addition, the origin and benefits of serverless were presented to explain its high adoption and success in the industry. In this chapter, the focus will be on the serverless platforms of cloud providers. Let's start with the evolution of cloud technology offerings over the years.

At the start of cloud computing, the primary offering of cloud providers was its provisioned and ready-to-use hardware, namely the infrastructure. Cloud providers manage hardware and networking operations, and therefore, the product they were offering was Infrastructure-as-a-Service (IaaS), as illustrated in the following diagram. All cloud providers are still offering IaaS products as their core functionality, such as Amazon Elastic Compute Cloud (Amazon EC2) in AWS and Google Compute Engine in GCP.

In the following years, cloud providers started to offer platforms...
