DESCRIPTION
MSFT operates very large datacenters worldwide. Lessons learnt from these large-scale deployments are delivered through Windows Server 2012 R2 and System Center 2012 R2, for private and hybrid cloud deployments. Ravi and Rajeev will walk you through SDN specific technologies shipping today as part of the Windows platform. This will include: - The Hyper-V Extensible vSwitch as the policy edge of the network - Hyper-V Network Virtualization as the overlay networking solution - Windows Gateways providing the bridge between networks, including Windows Azure - Using OMI for configuring the underlay network - Using System Center Virtual Machine Manager as a centralized network controller RSVP @ http://www.meetup.com/openvswitch/
