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 Kubeless

Kubeless is an open source and Kubernetes-native serverless framework that runs on top of Kubernetes. This allows software developers to deploy code into a Kubernetes cluster without worrying about the underlying infrastructure. Kubeless is a project by Bitnami, who is a provider of packaged applications for any platform. Bitnami provides software installers for over 130 applications, which allow you to quickly and efficiently deploy these software applications to any platform.

Kubeless functions support multiple programming languages, including Python, PHP, Ruby, Node.js, Golang, Java, .NET, Ballerina, and custom runtimes. These functions can be invoked with HTTP(S) calls as well as event triggers with Kafka or NATS messaging systems. Kubeless also supports Kinesis triggers to associate functions with the AWS Kinesis service, which is a managed data-streaming service by AWS. Kubeless functions can even be invoked at specified intervals using scheduled triggers...
