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.
Write short-lived functions in any language, and map them to HTTP requests (or other event triggers).
Deploy functions instantly with one command. There are no containers to build, and no Docker registries to manage.
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.
Fission is free and open source software.
Key Features
- 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.
- Builds on Kubernetes.
- Extensible to any programming language (Python, NodeJS, Go, C#, PHP are supported today). It abstracts away containers by default, but you can build your own containers if you need to.
