Tricircle
|
|
=========
|
|
|
|
The Tricircle provides an OpenStack API gateway and networking automation
|
|
funtionality 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 Tricircle and these managed OpenStack instances will use shared KeyStone
|
|
(with centralized or distributed deployment) or federated KeyStones for
|
|
identity management.
|
|
|
|
The Tricircle presents one big region to the end user in KeyStone. And each
|
|
OpenStack instance called a pod is a sub-region of the Tricircle in
|
|
KeyStone, and usually not visible to end user directly.
|
|
|
|
The Tricircle 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, and deal with
|
|
tenant level L2/L3 networking across OpenStack instances automatically. So it
|
|
doesn't matter on which bottom OpenStack instance the VMs for the tenant are
|
|
running, they can communicate with each other via L2 or L3.
|
|
|
|
The end user can see avaialbility zone(AZ) and use AZ to provision
|
|
VM, Volume, even Network through the Tricircle. One AZ can include many
|
|
OpenStack instances, the Tricircle 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.
