Cisco SD-WAN

What is SD-WAN, and what does it mean for networking, security, cloud?

SD-WAN has been around for a few years now, but it’s quickly becoming a buzzword in the networking world. In fact, it’s one of the most used terms at Cisco Live!. But what exactly is SD-WAN and what does it mean for networking, security, cloud? First, let’s take a look at the definition of SD-WAN, and then we’ll dive into what it’s used for. The hype around software-defined networking (SDN) is real, but it’s not always clear what it’s supposed to do for you. SDN and software-defined wide area networking (SD-WAN) are similar in that they both aim to make networks more flexible and agile, but they’re not the same thing. While SDN is a technology that can be used to enhance a wide variety of network services, SD-WAN is a more specific type of technology, designed to help companies ensure the availability and security of their remote network connections.
