SDN showdown: Examining the differences between VMware's NSX and Cisco's ACI

Ethan Banks, Owner, Packet Pushers Interactive | Jan. 7, 2014
The arrival of Software Defined Networking (SDN), which is often talked about as a game changing technology, is pitting two industry kingpins and former allies against each other: Cisco and VMware.

Conclusion
Philosophically, NSX and ACI are rather different. On the one hand, NSX touts rich virtual switch functionality, abstracting the network using a controller and overlays. On the other, ACI melds both hardware and software into a policy-driven network infrastructure built around the needs of specific applications.

Both approaches will impact IT operations. Are these solutions and SDN in general worth exploring? Yes. NSX and ACI are evidence that software defined networking is real, providing a technological foundation that will allow speedy, reliable application delivery for organizations.

Sure, it'll change how engineers exercise the art of networking. But sometimes change is good.
