Fission
Open source, Kubernetes-native serverless framework.
Overview
Fission is an open-source, Kubernetes-native serverless framework. It allows you to write short-lived functions in any language, and map them to HTTP requests or other event triggers. Fission takes care of the plumbing, managing the container lifecycle, scaling, and more, so you can focus on your code. It is designed to be fast, with a focus on low cold-start times.
✨ Key Features
- Fast cold starts (pools of warm containers)
- Language-agnostic (supports source code and Docker images)
- Runs on any Kubernetes cluster
- Built-in monitoring and logging integration (Prometheus)
- Automated Canary Deployments
- Workflows for orchestrating functions
🎯 Key Differentiators
- Focus on performance and low cold-start times through container pooling
- Emphasis on developer productivity and ease of use
- Does not require container images for simple functions (source-only deployments)
Unique Value: Achieve high-performance serverless on Kubernetes with fast cold starts and a focus on developer productivity.
