Learning Apache Openwhisk: Developing Open Serverless Solutions
With Early Release ebooks, you get books in their earliest form--the author's raw and unedited content as he or she writes--so you can take advantage of these technologies long before the official release of these titles. You'll also receive updates when significant changes are made, new chapters are available, and the final ebook bundle is released.
Serverless computing greatly simplifies software development. Your team can focus solely on your application while the cloud provider manages the servers you need. This practical guide shows you step-by-step how to build and deploy complex applications in a flexible multicloud, multilanguage environment using Apache OpenWhisk. You'll learn how this platform enables you to pursue a vendor-independent approach using preconfigured containers, microservices, and Kubernetes as your cloud operating system.
Michele Sciabarr demonstrates how to build a serverless application using classical design patterns and the programming language or languages that best fit your task. You'll start by building a simple serverless application hands-on before diving into the more complex aspects of the OpenWhisk platform.
- Examine how OpenWhisk's serverless architecture works, including the use of packages, actions, sequences, triggers, rules, and feeds
- Learn how OpenWhisk compares to existing architectures, such as Java Enterprise Edition
- Design applications using common Gang of Four design patterns
- Use architectural design patterns such as model-view-controller to combine several OpenWhisk actions
- Learn how to test and debug your code in a serverless environment
Michele Sciabarrà is a veteran of Information Technology, currently CEO of a consultancy focused on Kubernetes and Serverless solutions (sciabarra.com), and a contributor of the Apache OpenWhisk project: most notably he is the author of the runtime for the Go programming language.
