Introduction

Overview

OpenFunction is a cloud-native open source FaaS (Function as a Service) platform aiming to let you focus on your business logic without having to maintain the underlying runtime environment and infrastructure. You can generate event-driven and dynamically scaling Serverless workloads by simply submitting business-related source code in the form of functions.

Architecture and Design

Core Features

• Cloud agnostic and decoupled with cloud providers’ BaaS
• Pluggable architecture that allows multiple function runtimes
• Support both sync and async functions
• Unique async functions support that can consume events directly from event sources
• Support generating OCI-Compliant container images directly from function source code.
• Flexible autoscaling between 0 and N
• Advanced async function autoscaling based on event sources’ specific metrics
• Simplified BaaS integration for both sync and async functions by introducing Dapr
• Advanced function ingress & traffic management powered by K8s Gateway API (In Progress)
• Flexible and easy-to-use events management framework
