Think of it this way: Fabric Computing is the componentization and abstraction of infrastructure (such as CPU, Memory, Network and Storage). This is very much analogous to how OS virtualization componentizes and abstracts OS and application software stacks. Provisioning of the network, VLANs, IP load balancing, etc.
