Fission is a fast serverless framework for Kubernetes with a focus ondeveloper productivity and high performance.

Fission operates onjust the code: Docker and Kubernetes areabstracted away under normal operation, though you can use both toextend Fission if you want to.

Fission is extensible to any language; the core is written in Go, andlanguage-specific parts are isolated in something calledenvironments (more below). Fission currently supports NodeJS, Python, Ruby, Go,PHP, Bash, and any Linux executable, with more languages coming soon.

Fission maintains a pool of "warm" containers that each contain asmall dynamic loader. When a function is first called,i.e. "cold-started", a running container is chosen and the function isloaded. This pool is what makes Fission fast: cold-start latenciesare typically about 100msec.

We're built on Kubernetes because we think any non-trivial app willuse a combination of serverless functions and more conventionalmicroservices, and Kubernetes is a great framework to bring thesetogether seamlessly.

Building on Kubernetes also means that anything you do for operationson your Kubernetes cluster — such as monitoring or logaggregation — also helps with ops on your Fission deployment.

# Add the stock NodeJS env to your Fission deployment  $ fission env create --name nodejs --image fission/node-env# Create a function with a javascript one-liner that prints "hello world"  $ fissionfunctioncreate --name hello --env nodejs --code https://raw.githubusercontent.com/fission/examples/master/nodejs/hello.js# Run the function.  This takes about 100msec the first time.  $ fissionfunctiontest --name hello  Hello, world!
