When enterprise applications can seamlessly move between theirinternal & external clouds leveraging the elasticity & multi-tenancythat 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 extensionof 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) andconfiguration (for others).

This will require a convergence of

Current ideas, as well as

A slice of new technologies (like LISP) at appropriate levels to tacklethis 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 2for Services RDF/SPARQL, OWL

Cloud 1 / Cloud 2 transport XMPP

Cloud 1 selects; receivesprotocols, interface Web Services; REST API

Cloud 1 calls services inCloud 2 Metering, SLAs
