<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I am investigating on inter cloud resource federation across OS based cloud deployments, this is needed to support multi regions, cloud bursting, VPC and more use cases. I came
up with a design (link below) which advocate a new service (a.k.a. Alliance), this service sits close to Keystone and help abstracting all the inter cloud concerns from Keystone. This service will be abstracted from end users and there won’t be any direct
interactions between user and Alliance service. Keystone will be delegating all inter cloud concerns to Alliance.
