OpenFunction is a cloud-native, open-source Function-as-a-Service (FaaS) platform built on Kubernetes that lets developers deploy business logic as functions without managing underlying infrastructure. It supports both synchronous and asynchronous functions, builds OCI-compliant container images directly from source code, and provides scale-from-zero autoscaling and an event management framework.

Use cases

• run serverless functions on my own kubernetes cluster
• deploy functions from source code without writing dockerfiles
• build event-driven functions that consume from message queues
• scale functions from zero to N based on load
• self-hosted alternative to AWS Lambda
• process async events with functions on kubernetes
• integrate backend services with dapr bindings

When to choose

• you already run Kubernetes and want a self-hosted FaaS platform
• you need both sync (HTTP) and async (event-driven) functions in one platform
• you want scale-to-zero and event-metric-based autoscaling
• you want functions built into OCI images directly from source
• you prefer cloud-agnostic, pluggable runtimes over vendor lock-in

When to avoid

• you have no Kubernetes cluster and don't want to operate one
• you want a fully managed serverless offering with zero ops
• you need a lightweight function runtime without Kubernetes dependencies
• your team is small and Knative/Dapr's operational complexity outweighs the benefits
