- Loop free layer two by sacrificing half the links.
- VM or workload mobility anywhere at any time.
Smaller shops might be fine with giving up a few links, but extending a L2 domain is asking for trouble. Larger shops need every link they can get and demand the flexibility to move a VM anywhere. So we are being forced down a road of L2 everywhere. How do we do it?
Our current model is broken, or better said, it's out dated. We need a technology that is adaptable to the movement of the application. This will take some time...
Right now though, we have VMs needing to move within pods or zones or even DCs. Yup and application teams still require L2 domains between all this mess. So how do we make everyone happy?
Its not the protocol we need but its the protocol we deserve.
