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.

Summary

In this chapter, we first described the four key considerations to analyze the requirements for the Kubernetes cluster setup. Then we studied the three groups of Kubernetes platforms: managed, turnkey, and custom. Each Kubernetes platform has been explained, along with their responsibility levels on infrastructure, Kubernetes, and applications. Following that, we created a production-ready Kubernetes cluster on GKE. Since Kubernetes is designed to run scalable applications, we studied how to deal with increasing or decreasing workload by autoscaling. Furthermore, we also looked at application migration without downtime in production clusters to illustrate how to move your applications to the servers with higher memory. Finally, we performed autoscaling and migration activities with a serverless function running in a production cluster to minimize the costs. Kubernetes and serverless applications work together to create reliable, robust, and scalable future-proof environments...
