The “TL;DR” for those who are interested is that this solution bypasses the normal iptables layer involved in most Kubernetes implementations to load balance traffic directly to Pods in the cluster. Servers/Hardware. Unfortunately, this appears to be GKE-specific. Nothing this time around. Virtualization.

Last week I had the opportunity to join John Troyer on the VMware Communities podcast. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February. emphasis mine).

The only major things missing from their "Starter Kit" suite they offer are the addition of VMware - not cheap if you choose to purchase it - as well as the addition of a blade (or two) to serve as controllers of the system. The UCS Manager software bundled with the system provides core functionality (see diagram, right).

Think of it this way: Fabric Computing is the componentization and abstraction of infrastructure (such as CPU, Memory, Network and Storage). The next step is to define in software the converged network, its switching, and even network devices such as load balancers. Provisioning of the network, VLANs, IP load balancing, etc.
