Fission is a fast serverless framework for Kubernetes that allows developers to run short-lived functions with low latency and high performance. It supports various programming languages like Go, Node.js, PHP and Python and has a cold start time of around 100ms. Fission is suitable for developers who want to set up their own serverless environment on Kubernetes and customize environment images.
