Hi All, 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.
https://wiki.openstack.org/wiki/Inter_Cloud_Resource_Federation Apart from basic resource federation use cases, Alliance service will add following features 1. UUID token support across cloud 2. PKI Token support 3. Inter Cloud Token Validation 4. Inter Cloud Communication to allow * Region/endpoint Discovery * Service Discovery * Remote Resource Provisioning 5. Resource Access Across Clouds 6. SSO Across Cloud 7. SSOut Across Cloud (or Inter Cloud Token Revocation) 8. Notification to propagate meter info, resource de-provisioning .... I would appreciate if you guys take a look and share your perspective. I am open to any questions, suggestions, discussions on the same. Thanks for your time, Arvind Please excuse any typographical error.
