Heat/Vocabulary

This is a comparison of the equivalent vocabulary for describing the primitives used during orchestration. The first column references This DSL.

This is work in progress. Experts please amend as appropriate, and more comments at right or underneath.

This DSL	CFN	TOSCA	CAMP	Comments
Component	juju charm; puppet, chef roles	Node Template	Application Component, Platform Component	Maybe a AWS::CloudFormation::Init section at a stretch? Answer: no.
Blueprint	template	Service Template / Topology Template	Assembly Template
Deployment	stack	service instance (note: the TOSCA spec does not explicitly define instance objects)	Assembly
Static Resource	more properties/metadata	Deployment Artifact	Application Component Template
Deployment Resource	resource	Node Template / Deployment Artifact	Application Component	Mostly the same
Options	Parameter declarations	Node- and Relationship Type Properties
Inputs	Parameters	Properties defined in Node- and Relationship Templates	Parameters	CAMP Parameters = WIP
Constraints	Parameter constraints	Property Constraints or restrictions in XSD
Provider	(none)	covered by Capabilities concept; instantiated Node Types could act as proviers, where the Node Type Implementation would be the provider implementation	(out of scope, related to requirements and capabilities)	Resource Plugin exposed so the user can choose the plugin they want? Answer: An abstraction for implementation details.
Environment	(none)	not defined; Requirements can be expressed against the environment	(out of scope, related to requirements and capabilities)	An Environment may span multiple providers in multiple clouds
