CNCF Intro & Demo - OpenFaaS framework
6 likes1,451 views
OpenFaaS is a serverless framework that allows users to build and deploy containerized functions. It provides an easy way to deploy stateless container functions that scale horizontally. OpenFaaS grew from an idea to run Lambda functions on containers and has since expanded to support Kubernetes and external providers. It aims to provide portability, ease of use, simplicity and avoid vendor lock-in while leveraging existing Docker skills.

- 5. How did OpenFaaS come about? STORY SO FAR • “Lambda but on containers for Alexa” • Dockercon Cool Hacks - “push Docker beyond what it was made to do” • Major changes since Dockercon • Top trending Open Source project overall • > 4.4k stars • Kubernetes & external provider support • Asynchronous processing via NATS • CLI - templating • Regular contributors & Slack Community
- 6. What is OpenFaaS? "A SERVERLESS FRAMEWORK BUILT ON CONTAINERS" • Basic primitive: containers in OCI format • Container security • r/o filesystem, privilege drop, content trust • Manage functions with scheduler/orchestrator • Rich container eco-system - commercial & community • Avoid vendor lock-in • Run anywhere - cloud or on-prem • Leverage existing skills in teams (including Windows) • Anything can be a function.
