Claim:
1. A multi-tenant datacenter having Layer 2 architecture to maintain original client Layer 2 configurations without reconfiguration or virtualization of client systems and permit software defined networking, comprising: a plurality of physical client systems in a first datacenter each physical client system having a set of physical infrastructure resources and an original Layer 2 configuration; and a first cloud computing environment established in the first datacenter having Layer 2 architecture to maintain the original client Layer 2 configurations, and coupled to the physical client systems by OSI Layer 2 for the transfer of data frames prior to an OSI Layer 3 connection, each frame having a plurality of OSI Layer 2 tags applied prior to a Layer 3 activity permitting at least two client systems to have overlapping VLANs, the first cloud computing environment thereby virtually extending the physical infrastructure resources of each physical client system, wherein each client system maintains client's original Layer 2 configuration without reconfiguration or virtualization, and may self direct software defined networking.
