Verplanke believes that DPDK (Data Plane Development Kit) and virtualization are key to virtualizing workloads that move around lots and lots of packets, such as firewalls, routers, and other similar functions. In recent years, we’ve seen more devices running off-the-shelf software (like Linux). Intra-VM communication.

Infrastructure Orchestration abstracts and defines/configures the infrastructure world (I/O, NIC cards, HBA cards, storage connectivity, LANs, switches, etc.).
