At the moment, not really. You can set up a standalone Heat server and point it at an existing OpenStack cloud, but only one cloud at a time (and increasingly many features will not work with this setup). There is a blueprint for multi-region support in progress, and we hope to extend that to multi-cloud in the future.

Heat does not now, and probably will never, support instantiating resources on AWS. However, it does support the majority of the CloudFormation template format and a lot of the AWS resource types, so it may be possible to write a CloudFormation template that is deployable both by AWS and by OpenStack.

Thanks for your response, Look at the following link : http://docs.openstack.org/developer/h.. . which shows to get Heat to work with a remote OpenStack. Is it works ?

Your link is broken; it should be: http://docs.openstack.org/developer/h...

That does work, but only for one OpenStack cloud at a time. You can't connect one standalone Heat to multiple OpenStack clouds simultaneously.

Folks have talked about using multiple backends (for example, supporting an AWS backend by replacing auth and the key api functions) for things like internal/external autoscale, but the pain is not worth the gain. If you really want to scale across different cloud providers, you could easily(?) write your own shell script hooks to get the job done.
