Introduction
OpenFaaS - Serverless Functions Made Simple¶
OpenFaaS® makes it easy for developers to deploy event-driven functions and microservices to Kubernetes without repetitive, boiler-plate coding. Package your code or an existing binary in a Docker image to get a highly scalable endpoint with auto-scaling and metrics.
Highlights
- Ease of use through UI portal and one-click install
- Write functions in any language for Linux or Windows and package in Docker/OCI image format
- Portable - runs on existing hardware or public/private cloud - Kubernetes and Docker Swarm native
- CLI available with YAML format for templating and defining functions
- Auto-scales as demand increases
