Over the summer, you probably heard a lot of buzz about SD-WAN and how this new technology will revolutionize the way we do business. Hitting the mass media's attention in mid-2017, SD-WAN is heralded as being "the next big thing" to revamp the Wide Area Network. However, if you're not fluent in network speak, the jargon being thrown around by high-tech experts is probably whizzing in one ear and out the other. We're about to give you a crash course in SD-WAN technology, including why your company might soon be using it. Sit tight in your chair, because it's time to blast into the future.
The Basics of SD-WAN
In a nutshell, Software-Defined Wide Area Network (SD-WAN) is the younger sibling of Software Defined Network (SDN). SD-WAN was created to improve the user experience of the wide area network (WAN). It allows for a larger array of options for top-quality network connectivity and visibility. SD-WAN is primarily used to join different networks together, even if there are large geographical separations at play. For instance, this technology can connect separate office networks to a singular main business network. SD-WAN also uses cloud technology, so expensive hardware installation isn't required here.
SD-WAN's Biggest Perks
There are a variety of reasons why tech experts are singing SD-WAN's praises. Since you don't have to call up the IT department to install SD-WAN, switching to this new technology is relatively quick and easy. Besides slashing the costs of installation, SD-WAN is also believed to save companies money in the long run. Some businesses have found that SD-WAN can forego Multiprotocol Label Switching (MPLS) connections. By using broadband services instead, which is largely more cost-effective and easily available, SD-WAN is less expensive overall.
Other perks of SD-WAN relate to its superior levels of security, connectivity, and reliability. On SD-WAN, network traffic is fully encrypted and secured during its travels between networks and within the cloud. The connectivity isn't affected by geological distance and app performance is actually enhanced, leading to an improved user experience. Finally, SD-WAN is more reliable, since it increases network visibility. Thus, any problems are addressed sooner and more easily.
