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. Youโll learn how this platform enables you to pursue a vendor-independent approach using preconfigured containers, microservices, and Kubernetes as your cloud operating system.
Michele Sciabarrร demonstrates how to build a serverless application using classical design patterns and the programming language or languages that best fit your task. Youโll start by building a simple serverless application hands-on before diving into the more complex aspects of the OpenWhisk platform.
