You need to be prepared for this by choosing architectures that will be able to rapidly scale as use grows. The reasons for this frequent choice is due to the architectural traits of these database systems. The horizontally scaling architectures of these database engines can easily grow to match user demand.

I’d heard of Plumgrid, but wanted to take this time to better understand their architecture. As it turns out, their architecture is quite interesting. Using eBPF, Plumgrid has created in-kernel virtual network functions (VNFs) that do things like bridging, routing, network address translation (NAT), and firewalling.

SDN wasn’t (and isn’t) about virtualizing network switches, routers, or firewalls; that’s NFV (Network Functions Virtualization). Similarly, running storage controller software as virtual machines isn’t software-defined storage, it’s the storage equivalent of NFV (SFV?).
