Trio2o

The Trio2o provides an OpenStack API gateway to allow multiple OpenStack instances, spanning in one site or multiple sites or in hybrid cloud, to be managed as a single OpenStack cloud.

The Trio2o and these managed OpenStack instances will use shared KeyStone (with centralized or distributed deployment) or federated KeyStones for identity management.

The Trio2o presents one big region to the end user in KeyStone. And each OpenStack instance called a pod is a sub-region of the Trio2o in KeyStone, and usually not visible to end user directly.

The Trio2o acts as OpenStack API gateway, can handle OpenStack API calls, schedule one proper OpenStack instance if needed during the API calls handling, forward the API calls to the appropriate OpenStack instance.

The end user can see avaialbility zone(AZ) and use AZ to provision VM, Volume, through the Trio2o. One AZ can include many OpenStack instances, the Trio2o can schedule and bind OpenStack instance for the tenant inside one AZ. A tenant's resources could be bound to multiple specific bottom OpenStack instances in one or multiple AZs automatically.

Description
Trio2o is to provide APIs gateway for multiple OpenStack clouds to act as a single OpenStack cloud.
