Hi all,

I’m very pleased to announce a new project, Picasso[1][2] - Functions as a
Service (FaaS).

The mission is to provide an API for running FaaS on OpenStack, abstracting
away the infrastructure layer while enabling simplicity, efficiency and
scalability for both developers and operators.

Picasso can be used to trigger functions from OpenStack services, such as
Telemetry (via HTTP callback) or Swift notifications. This means no long
running applications, as functions are only executed when called.

Picasso is comprised of two main components:

   - Picasso API
      - The Picasso API server uses Keystone authentication and
      authorization through its middleware.
   - IronFunctions
      - Picasso leverages the backend container engine provided by
      IronFunctions <https://github.com/iron-io/functions>, an open-source
      Serverless/FaaS platform based on Docker.


   - Wiki
      - https://wiki.openstack.org/wiki/Picasso

      - Architecture
      - Picasso deployment architecture
      - Picasso/IronFunctions inter-component architecture

   - Examples
      - Triggering functions from Telemetry and Aodh

      - Application that queries Nova for a list of running servers

We’ve created some initial blueprints
<https://blueprints.launchpad.net/picasso> to show what the future roadmap
looks like for the project.

You can try out Picasso now on DevStack by following the quick start guide
Let us know what you think!
