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. 9 Presentation_ID © 2008 Cisco Systems, Inc.

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 ? 10 Presentation_ID © 2008 Cisco Systems, Inc.
