Regardless of how one might “feel” about SDN, the notion of agility in service delivery wherein the network can be exposed and consumed as a service versus a trunk port and some VLANs is…the right thing. Just because the network is “flat” doesn’t mean it’s services are or that the delivery of said services are any less complex. I just wrote about this here: The Tyranny Of Taming (Network) Traffic: Steering, Service Insertion and Chaining…
“Flat networks” end up being carved right back up into VLANs and thus L3 routing domains to provide for isolation and security boundaries…and then to deal with that we get new protocols to deal with VLAN exhaustion, mobility and L2 stretch and…
It seems like some of the people at the Gartner DC show (from this and other tweets as I am not there) are abjectly allergic to abstraction beyond that which they can physically exercise dominion.
