Hyperscale Data Centers: WinterGreen Research study: Market Shares, Strategies, and Forecasts, Worldwide, 2017-2023.  Worldwide hyperscale data center markets are poised to achieve unprecedented growth as enterprise data centers are upgraded to manage quantum increases in data traffic.  Apps and wireless smart phones drive huge increases in data traffic causing a bottleneck in the enterprise data center, creating the need to migrate workload off the enterprise data center to the hyperscale data center.  

Facebook next-generation data center network design is based on a fabric implementation.  Facebook redefined the datacenter and addressed the challenge of making the entire data center building one high-performance network.   Instead of a hierarchically oversubscribed system of clusters, the fabric can support high traffic data exchange across the servers with a clear and easy path.  Network functions virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.  This is an essential aspect of cloud 2.0.  Base orchestration enhancements provided by hyperscale data centers include high-speed access to low-latency, durable storage, APIs for NFV, and VM migration to deliver transparent availability in the face of system maintenance.  Andromeda is a re-working of Google underlying network virtualization architecture, and its SDN core.  Enhancements enable rapid iteration and delivery of new functionality.  This positions the Google cloud platform network as an agent of disruption to all cloud computing.
