1. Established Trust Relationship

2. Compatible Infrastructure


When enterprise applications can seamlessly move between their internal & external clouds leveraging the elasticity & multi-tenancy that a cloud infrastructure offers

Extend secure data center to the cloud computing era

In order to get a portion of the SP cloud as a „seamless extension‟ of the enterprise data center, one also needs

• To migrate network context like VPN/VRF, VLAN, Load Balancing, firewall/NAT, QoS and may be some port profiles (for IKV/1K/5K) and configuration (for others).

This will require a convergence of

• Current ideas, as well as

• A slice of new technologies (like LISP) at appropriate levels to tackle this challenge.

Inter-Cloud: Key Questions

What is the “network model” ?

-network-based isolation for the multitenant SP cloud

-network abstractions for the enterprise tenants (seamless)

What are the “network features” that differentiate?

- isolation (per above), QoS, monitoring, CPE linkages

How are the network features exposed/integrated?

- control APIs (and underlying abstractions)

- cloud OS linkages

To what extent will we support workload mobility?

- live migration requirement?

- moving workload context

-Dude, where is my VM ?

Inter-Cloud In A Nutshell


Inter-Cloud ExampleDynamic Workload Migration – Simple VM Mobility

Cloud 1 finds Cloud 2→ Naming, Presence

Cloud 1 trusts Cloud 2→ Certificates, Trustsec

Cloud 1/2 negotiate→ Policy, Entitlement, Security, Metering

Cloud 1 / Cloud 2 transport→ XMPP

Cloud 1 sets up Cloud 2→ Placement, Deployment, Format, Motion

Cloud 1 sends to Cloud 2→ Transfer, Management

VM Runs in Cloud 2→ Addressing, VLAN, WWN, Filesystem


Inter-Cloud ExampleDynamic Workload Federation – Generalized Service Access

Cloud 1 finds Cloud 2→ Naming, Presence

Cloud 1 trusts Cloud 2→ Certificates, Trustsec

Cloud 1 queries Cloud 2 for Services→ RDF/SPARQL, OWL

Cloud 1 / Cloud 2 transport→ XMPP

Cloud 1 selects; receives protocols, interface→ Web Services; REST API

Cloud 1 calls services in Cloud 2→ Metering, SLAs
