As companies flow extra towards cloud computing, one very important issue for achievement is adopting multi-tenant software-defined networking (SDN) ideas in info facilities. Hyper-V community Virtualization (HNV) is a key enabler for a multi-tenant SDN resolution and is vital for enforcing a hybrid cloud atmosphere the place tenants can convey not just their very own IPs, yet their whole community topology because the virtualized networks are abstracted from the underlying textile community. community virtualization generally and Hyper-V community Virtualization particularly are fairly new innovations. in contrast to server virtualization, that is a mature, widely-understood expertise, community virtualization nonetheless lacks this type of vast familiarity.

The advantage of this approach is that Fabrikam can offer “bring your own IP or subnet” cloud services to multiple customers with overlapping IP address ranges. 0/24). As a result, Fabrikam must create a separate physical network for each tenant. This limits the flexibility Fabrikam can offer to customers and impedes business scalability. 0/24 in the Woodgrove Bank VLAN. There are several disadvantages of this approach: On-boarding of each tenant requires VLAN configuration of routers, switches, and hosts in the Fabrikam network.
Info Implementing cloud computing with Network Virtualization he previous chapter examined the internal workings of Hyper-V Network Virtualization (HNV). This chapter will identify some key cloud computing scenarios and examine how HNV helps cloud service providers enable these scenarios. It will also cover the different gateway functionalities in Windows Server 2012 R2. Key cloud computing scenarios enabled by HNV Cloud computing enables organizations to leverage the compute, storage, and networking infrastructure of a cloud services provider to meet their business needs with agility and minimal capital expenditure.
The Hyper-V switch broadcasts the ARP to the HNV filter. The HNV filter responds to the ARP with MACDFGW. MACDFGW is associated with the HNV filter itself. 1 in this case. 1) on VSID 5001 (included in the OOB data for this MAC address). Contoso1 sends an IP packet destined for the physical Contoso server with the MAC address of the default gateway so that the packet is delivered to the default gateway to be routed appropriately. This packet is delivered to the Hyper-V switch and gets the VSID associated (5001) with the sender’s VM network adapter as out-of-band (OOB) data.
