Getting Started with IBM OpenWhisk

OpenWhisk is an open-source serverless compute platform. It executes your functions (actions) in response to events from triggers. It costs nothing when not in use.

Cost-Effective Computing

Pay only for the exact time your actions run, down to a fraction of a second. When an action is not working, it’s not in memory, so you don’t pay anything.

Super-Granular Scaling

Run your action thousands of times in just seconds, or a week, or just once a week. Action instances scale to meet demand exactly, then disappear.

Easy Integration

Trigger your actions from events in your favorite services, or directly via REST API. Interact with services directly in code or use our library of community packages.
