The Heat developers are pleased to announce the release of the Heat API version 4. We have added many new features including Ubuntu Precise host support. Heat is a project designed to work with OpenStack that provides a programmable interface to orchestrate multiple cloud applications implementing CloudFormation. To give it a spin on Fedora 17: https://github.com/heat-api/heat/blob/master/docs/GettingStarted.rst#readme Or on Ubuntu 12.04: https://github.com/heat-api/heat/wiki/Getting-Started-with-Heat-using-Master-on-Ubuntu Enhancements in version 4: + Cloud Watch high availability. Heat monitors services and VMs and can restart them or send alarms on failure. Also supported is escalation of service failure which can result in an instance restart. This is similar to the AWS CloudWatch functionality. https://github.com/heat-api/heat/wiki/Roadmap-Feature:-High-Availability + Authentication and identification. Heat now performs proper authentication on all API calls, identifying individual users, and creating stacks on a per-user basis. Heat now also supports AWS style keys as well as keystone username/password or token authentication. https://github.com/heat-api/heat/wiki/Roadmap-Feature:-Associate-users-with-templates-using-keystone + Nested stack support. Heat templates can now reference other templates enabling you to use them as building blocks to create larger deployments. https://github.com/heat-api/heat/wiki/Roadmap-Feature:-Nested-stacks + IAM::User support. https://github.com/heat-api/heat/wiki/Roadmap-Feature:-AWS-template-support-parity + API rework to align with AWS.
