API Gateway supportAllows to map API endpoints to OpenWhisk actions. API Gateway takes care of security, control (e.g. rate limiting), mediation, parameter mapping, schema validation & supports different verbs

Web actions

Serverless microservice APIs/backend

What is OpenWhisk good for?

Another way to invoke an action is via our newest web action capabilities. Those OpenWhisk actions quickly enable you to build web based applications. Allowing backend logic which your web application can access anonymously without requiring an OpenWhisk authentication key. It is up to the action developer to

IBM Bluemix OpenWhiskOpenWhisk & Containers

Basically, OpenWhisk is based on Docker… but we added some smartness to meet our performance goals…

Behind the scenes: It’s about containers

This ecosystem allows you…… to run short running scalable functions in a serverless fashion and … longer running processes on a containerized infrastructure also forming the basis for the said serverless platform
