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
