Bluemix is built on 4
key open compute
technologies:
OpenWhisk, Cloud
Foundry, Docker, and
OpenStack, and
delivered by 3
deployment options:
Public, Dedicated and
Local.
It extends each of
these with a growing
number of services,
robust DevOps
tooling, integration
capabilities, and a
seamless developer
experience.

API Gateway
support
Allows 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

IBM Bluemix OpenWhiskWhat is serverless good for?
Volatile workload that can
be split in smaller short-
running pieces.
Suited for sporadic as well
as heavy load scenarios.
