The new Windows Server Technical Preview 3 topic Deploy Software Defined Networks using scripts demonstrates how you can deploy a Microsoft Software Defined Network infrastructure by using Windows PowerShell scripts.
The infrastructure includes a single node Network Controller, a Software Load Balancer (SLB)/MUX, virtual networks with Hyper-V Network Virtualization, and associated access control lists (ACLs). Additionally, another script deploys a tenant workload with which you can experiment.
With this script deployment you also deploy Windows Server Gateway, including a forwarding gateway, a site-to-site IPsec gateway, and a Generic Routing Encapsulation (GRE) gateway.
