Fission is a fast serverless framework for Kubernetes with a focus on developer productivity and high performance.
Fission operates on just the code: Docker and Kubernetes are abstracted away under normal operation, though you can use both to extend Fission if you want to.
Fission is extensible to any language; the core is written in Go, and language-specific parts are isolated in something called environments (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 a small dynamic loader. When a function is first called, i.e. "cold-started", a running container is chosen and the function is loaded. This pool is what makes Fission fast: cold-start latencies are typically about 100msec.
We're built on Kubernetes because we think any non-trivial app will use a combination of serverless functions and more conventional microservices, and Kubernetes is a great framework to bring these together seamlessly.
Building on Kubernetes also means that anything you do for operations on your Kubernetes cluster — such as monitoring or log aggregation — 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"
$ fission function create --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.
$ fission function test --name hello
