As cloud-based communications become more of the natural fabric of business communications infrastructure, SD-WAN is becoming more important for the enterprise. And this is precisely the reason we chose an SD-WAN company (BigLeaf) to present the keynote at Virtual AstriCon, November 3-4, 2021. It is an essential subject to customers who may want to use it or partners who likely will need to offer this as one of their solutions to help their customers.
What is SD-WAN (Software-defined Wide Area Network)? First, let’s review how connectivity occurred before SD-WAN. A WAN for a company would be how a company connects different locations and sends data back and forth in a private manner (i.e., not using the open internet). Obviously, this has been happening for a long time via routers using MPLS. One could encrypt traffic over the MPLS network. All traffic back and forth between locations would use MPLS on this private network.
However, public clouds such as AWS and Azure are being used now with enterprises. Interaction with these public clouds is occurring within the enterprise. With SD-WAN, one can intelligently route traffic – send the traffic either over private WAN links or the internet depending on policies set up. Since some traffic doesn’t need to be on the private WAN, or some traffic will be on public clouds anyway, SD-WAN can manage this. You can scale easier and faster, can drive traffic flows, etc.
Firewalls also have to be set up when interaction with the internet occurs, and these are known as (believe it or not) NGFWs (Next-Generation Firewalls!). Some NGFWs have SD-WAN capability. And some do not, by design. And some SD-WANs have some NGFW capability, and some do not, also by design.
