Description

This project aims to define a tool- and cloud-independent specification to automate infrastructure provisioning, which, together with a Configuration Managment System like Chef or Puppet should for the first time fully deliver on the promise of "Infrastructure as code".

Amazon's Web Services recent outage has paradoxically highlighted the need for a tool like AWS CouldFormation that is vendor independent.

There are already Open Source cloud-agnostic libraries for cloud APIs (Fog, libcloud...), and several tools that make use of it (Chef's knife, Spiceweasel) but a tool-independent infrastructure specification is still missing.

Deployments are defined in JSON, following the same syntax as Chef's nodes, roles and cookbooks.

An example of the specification draft (from example.json):
