Cisco ConfidentialPresentation_ID 9 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. Virtual Private Inter-Cloud / CloudBursting

Cisco ConfidentialPresentation_ID 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 ?
