MARCH 31, 2023
The Pulumi program follows this overall flow: First, the program creates the base infrastructure objects that are required—a resource group, a virtual network, some subnets, and a network security group. This load balancer is used only for Kubernetes API traffic.) The last step is to bootstrap the cluster.

On Network Virtualization and SDN
Scott Lowe
APRIL 30, 2013
Is there a difference between network virtualization and Software-Defined Networking (SDN)? So, in a similar fashion to my post on network overlays vs. network virtualization , I thought I’d weigh in with some thoughts. With this definition in hand, let’s compare network virtualization to SDN.
