Multi-Tenant Network Req’s

• Tenant wants to easily move VMs to/from the cloud

• Hoster wants to place VMs anywhere in the data center

• Both want: Easy Onboarding, Flexibility & Isolation

Cloud Data Center Woodgrove Bank Blue 10.1.0.0/16

Contoso Bank Red 10.1.0.0/16

One Solution: PVLAN

• Isolation Scenario

• Hoster wants to isolate all VMs from each other and allow internet connectivity

• #1 Customer Ask from hosters

• Community Scenario

• Hoster wants tenant VMs to interact with each other but not with other tenant VMs

• Requires a VLAN id for each “community” (limited scalability, only 4095 VLAN IDs)

Generic Routing Encapsulation • 1 Provider Address per HOST (shared by all VMs on the host)

• Embed Tenant Network ID in the GRE header Key field

Address Virtualization Summary

IP Rewrite Performance and

Compatibility

No need to upgrade existing NICs, existing switches, and existing network appliances

Immediately and incrementally deployable today without sacrificing performance

GRE Encapsulation Deeper Multi-Tenancy

Integration

Standards based – RFCs 2784 & 2890

As few as one IP address per host lowering burden on the switches Full MAC headers and explicit Tenant Network ID marking supports for traffic analysis, metering and control Any encapsulation will break stateless offloads in the host server (LSO, Checksum, RSC, RSS, VMQ)
