API server: HTTP REST API service for heat.
CFN: An abbreviated form of "AWS CloudFormation".
Constraint: Defines valid input parameters for a template.
Dependency: When a resource must wait for another resource to finish creation before being created itself. Heat adds an implicit dependency when a resource references another resource or one of its attributes <resource attribute>. An explicit dependency can also be created by the user in the template definition.
Environment: Used to affect the run-time behavior of the template. Provides a way to override the default resource implementation and parameters passed to Heat. See Environments.
Heat Orchestration Template: A particular template format that is native to Heat. Heat Orchestration Templates are expressed in YAML and are not backwards-compatible with CloudFormation templates.
HOT: An acronym for "Heat Orchestration Template".
Input parameters: See Parameters.
Metadata: May refer to Resource Metadata, Nova Instance metadata, or the Metadata service.
Metadata service: A Compute service that enables virtual machine instances to retrieve instance-specific data. See Metadata service (OpenStack Cloud Admin Guide).
Multi-region: A feature of Heat that supports deployment to multiple regions.
Nested resource: A resource instantiated as part of a nested stack.
Nested stack: A template referenced by URL inside of another template. Used to reduce redundant resource definitions and group complex architectures into logical groups.
Nova Instance metadata: User-provided key:value pairs associated with a Compute Instance. See Instance specific data (OpenStack Operations Guide).
OpenStack: Open source software for building private and public clouds.
Orchestrate: Arrange or direct the elements of a situation to produce a desired effect.
Outputs: A top-level block in a template that defines what data will be returned by a stack after instantiation.
Parameters: A top-level block in a template that defines what data can be passed to customise a template when it is used to create or update a stack.
Provider resource: A resource implemented by a provider template. The parent resource's properties become the nested stack's <nested stack> parameters. See What are "Providers"? (OpenStack Wiki).
Provider template: Allows user-definable resource providers <resource provider> to be specified via nested stacks <nested stack>. The nested stack's outputs become the parent stack's attributes <resource attribute>.
Resource: An element of OpenStack infrastructure instantiated from a particular resource provider. See also Nested resource.
Resource attribute: Data that can be obtained from a resource, e.g. a server's public IP or name. Usually passed to another resource's properties <resource property> or added to the stack's outputs.
Resource group: A resource provider that creates one or more identically configured resources <resource> or nested resources <nested resource>.
Resource Metadata: A resource property that contains CFN-style template metadata. See AWS::CloudFormation::Init (AWS CloudFormation User Guide)
Resource plugin: Python code that understands how to instantiate and manage a resource. See Heat Resource Plugins (OpenStack wiki).
Resource property: Data utilized for the instantiation of a resource. Can be defined statically in a template or passed in as input parameters <parameters>.
Resource provider: The implementation of a particular resource type. May be a Resource plugin or a Provider template.
Stack: A collection of instantiated resources <resource> that are defined in a single template.
Stack resource: A resource provider that allows the management of a nested stack as a resource in a parent stack.
Template: An orchestration document that details everything needed to carry out an orchestration <orchestrate>.
Template resource: See Provider resource.
User data: A resource property that contains a user-provided data blob. User data gets passed to cloud-init to automatically configure instances at boot time. See also User data (OpenStack End User Guide).
Wait condition: A resource provider that provides a way to communicate data or events from servers back to the orchestration engine. Most commonly used to pause the creation of the stack while the server is being configured.
