7 Need for Network Overlays 7

8 Needs of a Modern Day Cloud Enabled Data Center Automation Programmability Policy Flexible, on-demand overlays with underlay awareness Support scale out architectures Auto provision resources Visibility, Management & Troubleshooting Exposed standardized northbound APIs Support physical and virtual workloads Provide vendor agnostic southbound communication channels Intent driven, declarative and transactional Simplified, application oriented interfaces to the user Granular, policy driven instantiation of network overlays 8

9 Network Overlays/SDN in the Datacenter Separates virtual network configuration and topologies from the physical (underlay) networks VXLAN / MPLS DCI Allows redesign and upgrade of the physical network without affecting the virtual topology OVS OVS DVS DVS VTF Provides much more flexibility for the rapid creation, updating, and deletion of networks Provision a fast underlay unfettered by policy and control 9

10 Drivers for Overlay Networking in Data Center Simplified workload provisioning Multi-tenancy at scale Flexible workload placement/mobility 10

22 VTS Use Cases Multi-Tenant Data Centers Network-Function Virtualization 22

23 Multi-tenant Private Cloud Cloud Management Platform NETCONF 96*40GE REST API VTS To DC Router 40GE Link 10GE Link GE Link Hardware Based VxLAN GW DSW (DC Switch) PSW (Pod Switch) Region 1 PoD 1 4*40GE PoD N Region 2 EBGP based Underlay ASW (Access Switch) VPC 23 23

24 Multi-Tenant Private Cloud In FSI, customers have used the separated or isolated infrastructures for the sake of compliances. For example, a large US FSI has the following three infrastructures: Investment Banking Intranet (INET1) Corporate Financing Intranet (INET2) Global IT Intranet (INET3) The hardware resource waste resulted from three sets of infrastructures is horrendous. Leveraging Cisco s software overlay SDN will allow them to tap into the unused compute capacity and avoid hardware acquisition. Global Transport Internet (The Backbone) Firewall Firewall INET1: Investment Banking INET1 Campus Firm-Wide Campus INET1 Compute Farm INET3 Global IT Intranet Firm-Wide Compute Farm INET2: Corp Fin Intranet INET2 Campus INET2 Compute Farm 24
