How I Learned to Hate the DCI: Layer 2 data center interconnects (DCI) is still alive and well. I blame VMware with vMotion and now every other Hypervisor vendor on the planet.

Why the NOS will decouple
Over the next couple of years some of us expect the networking industry to have some fairly significant changes. There are really two options: A distributed approach we have today or a controller based centralized model.

Death to the Firewall
[fancy_header3 variation=”slategrey”]Death to the Firewall[/fancy_header3] The Firewall will die soon. Blackbox hardware just doesn’t make sense anymore.
