## What it is
Apache OpenWhisk is an open source distributed serverless (FaaS) cloud platform that executes functions in response to events at any scale using Docker containers. It supports actions in many languages, event triggers and rules, and deploys on Kubernetes, OpenShift, Docker Compose, and other container platforms.

## Use cases
- run functions in response to events without managing servers
- self-host a serverless functions platform on kubernetes
- build serverless apis from functions
- compose functions into serverless workflows
- connect event feeds to functions with triggers and rules
- deploy a faas platform locally for development

## When to choose
- you need an open source, self-hosted alternative to AWS Lambda or Cloud Functions
- you want polyglot function runtimes including custom Docker-based actions
- you deploy on Kubernetes or OpenShift and want Helm-based serverless
- you need event-driven architecture with triggers, rules, and feeds

## When to avoid
- you only need managed serverless without infrastructure overhead
- your workloads are long-running rather than short event-driven functions
- you prefer a simpler single-node function runner
- your team cannot operate a distributed container-based platform

## Facets
- artifact type: service
- maturity: active
- function: serverless, deployment, workflow-automation, scheduling, api-framework, cli
- domain: cloud-computing, backend, apis, microservices
- platform: cloud, self-hosted, cross-platform
- tags: faas, functions-as-a-service, event-driven, apache, scala, serverless-platform, triggers, actions, devops, docker, kubernetes
