Agree with Kevin,

Currently Tricircle mainly focuses on the API gateway and networking automation across multiple OpenStack instances. The hybrid cloud PoC is built based on Tricircle in Tokyo Summit: https://www.openstack.org/summit/tokyo-2015/videos/presentation/huawei-openstack-enabled-hybrid-cloud

Where Tricircle manages multiple small OpenStack instances, and different OpenStack instance using "jacket" to integrate AWS/vCloud. The jacket provide a way of abstract of hybrid cloud.

Hi Gordon,

Thank you for your suggestion.

I think jacket is different from tricircle. Because tricircle focuses on OpenStack deployment across multiple sites, but jacket focuses on how to manage the different clouds just like one cloud.  There are some differences:
1. Account management and API model: Tricircle faces multiply OpenStack instances which can share one Keystone and have the same API model, but jacket will face the different clouds which have the respective service and different API model. For example, VMware vCloud Director has no volume management like OpenStack and AWS, jacket will offer a fake volume management for this kind of cloud.
2. Image management: One image just can run in one cloud, jacket need consider how to solve this problem.
3. Flavor management: Different clouds have different flavors which can not be operated by users. Jacket will face this problem but there will be no this problem in tricircle.
4. Legacy resources adoption: Because of the different API modles, it will be a huge challenge for jacket.

I think it is maybe a good solution that jacket works to unify the API model for different clouds, and then using tricircle to offer the management of  a large scale VMs.

Best Regards,
Kevin (Sen Zhang)
