WAN optimization has been with us for a long time. Born alongside the expensive MPLS data service, WAN optimization appliances allowed organizations to squeeze more bandwidth out of thin pipes through compression and deduplication, as well as prioritizing traffic of loss-sensitive applications such as remote desktops.

In recent years, the rapid development of cloud-based networking, network abstractions such as SD-WAN, and controller-based campus networking has meant that basic, day-to-day network operations have become easier for non-network engineers. For example, a cloud engineer may be a novice in how encapsulation technologies work.

I read with some surprise the interview with Zscalers CEO, Jay Chaudry, in CRN where he stated that the network firewalls will go the way of the mainframe, that the network is just plumbing and that Zscaler proxy overlay architecture will replace it with its application switchboard. The proxy firewalls faded. I guess not.

The market for SD-WAN has been driven in part by its ability to reduce bandwidth costs and improve the performance of cloud access. Traditionally, Wide Area Networks (WANs) and network security were loosely coupled entities. This amicable live-and-let-live separation falls apart with todays SD-WAN.
