 OpenStack project
Status changed from Stackforge to OpenStack under Heat program
https://github.com/openstack/heat-translator
http://docs.openstack.org/developer/heat-translator/
• Implementation of new TOSCA features – networking, block
storage, object storage, capabilities etc.
• Availability to use on command line
• Support for user input parameters
• Growing TOSCA ecosystem
• Implementation of TOSCA relationship templates, custom types

Kilo: Heat-Translator in Action!
• Clone the project
• heat_translator.py --template-file=translator/toscalib/tests/data/tosca_helloworld.yaml
--template-type=tosca
• Can provide input parameters per template need as, --parameters="purpose=test“
TOSCA YAML HOT YAML
Liberty plan:
o Implement CLIFF framework to build friendlier CLI
o Make Heat-Translator available to use in python-openstackclient (OSC) via plugin

Kilo: Network Modeling (Neutron)
• Application Model separate from Network Model
• Allows developers to Model JUST the application and
bind to existing tenant networks
• Supports a Plurality of Logical Public & Private Networks
• Connected via logical Ports nodes (via LinksTo and BindsTo)

Container Application Modeling
• Agnostic of PaaS Cloud Provider
• PaaS on OpenStack, Cloud Foundry, Azure, etc.

PaaS Layer exposes “runtimes”
as TOSCA Capabilities
• Docker, Nodejs, JSP, J2EE, etc.
Heat-Translator could automatically retrieve and
deploy a Docker image from a declared
Repository
• TOSCA Templates can model their repositories
(e.g., Docker Hub)
• Heat could dynamically “pull” templates, definitions,
scripts, configuration files, etc. from multiple repos.

TOSCA v1.0 intends to support policies in the areas of :
 Placement (Affinity), Scaling and Performance
‒ with Rules that are evaluated to execute Automatic and Imperative Triggers
Liberty Plans: Policies
Policies be modeled as Requirements using TOSCA Capability Types
1. That can be attached to Interfaces or specific Operations,
2. Nodes and
3. Groups of Nodes

Future Plans: Network Functions Virtualization (NFV)
Plan: Heat-Translator working with Neutron related OpenNFV projects
• TOSCA liaising with ETSI NFV and OpenNFV standards work groups
Support for NFV graph constructs:
TOSCA Profile Drafts model
Software Defined Networks (SDN) on OpenStack
• Support Network Service Descriptors (NSD)
• Virtual Network Function Descriptors (VNFD)
• Forwarding Graphs as sequences of Connection Points (CPs)
(In-Progress)
