FULL DISCLOSURE: I'm NOT working for RightScale and not for Gigaspaces ;-)

I guess you also can review RightScale option

Few interesting points:

• Self-Service Catalog
• Manage Application Life-cycle
• ETC ...

==========================

Also, very promising solution delivered by Gigaspaces, product Cloudify, would recommend to review it as well!

Good luck!

FULL DISCLOSURE: I work for Mirantis

Mirantis's FUEL offering is focused on OpenStack deployment and management.

My recommendation would be to review your needs, regarding the features you would need for concurrently managing multiple (geographically or otherwise) distinct cloud deployments.

If there are things you would find useful for the product to do, which are not currently implemented, you could file some feature requests with us, and quite possibly you'll see those features in a future version of FUEL.
