Kubernetes Native Serverless Functions with Fission

Tired of vendor locking your serverless functions? Say no more!

In this session, we’re going to dive into Fission, an easy to deploy and easier to use framework for Kubernetes native serverless functions. We’ll deploy Fission with flux and implement a function to handle our requests. Afterwards, we’ll explore the different methods to trigger functions and handle various kinds of events. Finally, we’ll explore the custom resource definitions and what’s behind the curtain of the framework.
