'Any service at any server in any cloud.' Next generation data centers should allow dynamic resource allocation and consolidation across large resource pools. The topological constrains of today’s data center networks limit how services can be assigned to servers. Windows Server 8 enables you to create an agile, multi-tenant cloud on top of your existing infrastructure by virtualizing the network. Network virtualization decouples server configuration from network configuration to provide a virtual dedicated network to each tenant. This allows seamless migration of workloads, while continuing to provide security isolation between tenants. Partners have the opportunity to become multi-tenancy aware and provide the next generation of services, devices, appliances, both physical and virtual, to augment and complete the Windows offering to build secure, scalable, multi-tenant public and private clouds.
