9. Virtual Private Inter-Cloud / CloudBursting
 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.

10. 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 ?

12. Inter-Cloud Example
Dynamic Workload Migration – Simple VM Mobility
Cloud 1 / Cloud 2 transport
→ XMPP
Cloud 1 finds Cloud 2
→ Naming, Presence
Cloud 1 trusts Cloud 2
→ Certificates, Trustsec
Cloud 1/2 negotiate
→ Policy, Entitlement,
Security, Metering
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 12

13. Inter-Cloud Example
Dynamic Workload Federation – Generalized Service Access
Cloud 1 / Cloud 2 transport
→ XMPP
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 selects; receives
protocols, interface
→ Web Services; REST API
Cloud 1 calls services in
Cloud 2
→ Metering, SLAs
