Fission is an open-source, Kubernetes-native serverless framework for deploying functions as a service (FaaS). Developers write functions in languages like Python, NodeJS, Go, Ruby, PHP, or Bash, and Fission runs them on Kubernetes with event triggers (HTTP, message queues, timers) while abstracting away containers and Docker, with ~100ms cold starts via warm container pools.
Use cases
- run lambda-like serverless functions on my own kubernetes cluster
- trigger functions from http requests or message queues
- deploy functions without building docker containers
- build an event-driven api with low cold-start latency
- self-host a functions-as-a-service platform in a private datacenter
- run scheduled serverless tasks on kubernetes
- migrate aws lambda workloads to a portable open-source platform
When to choose
- you already run kubernetes and want a native FaaS platform
- you need low cold-start latency from warm container pools
- you want to write functions in multiple languages without managing containers
- you need a portable, self-hosted alternative to AWS Lambda
- you want declarative specs you can check into source control
When to avoid
- you have no kubernetes cluster and want the simplest serverless option
- you need fully managed serverless with zero infrastructure to operate
- your workloads are long-running rather than short-lived functions
- you need a managed multi-cloud FaaS with vendor-backed SLAs
