SD-WANs The SMB Way

Industry Commentary
SD WAN technology is well understood in large enterprises and many medium-sized businesses. But small businesses have not yet caught on to their benefits, partly because of the complexity and cost – but also to a large extent because they don’t understand what SD-WAN it can bring to them.
A Software Defined Wide Area Network, or SD-WAN can mean many things to many people (principally which marketing person you are talking to!). But at its core is the ability to scale performance, increase reliability, and generally improve user experience. In its most general form, an SD-WAN allows an Managed Service Provider to “manage” the connectivity between multiple sites – either physical offices or cloud setups – without having to go out there and physically reconfigure routers or install new ISP connections.
Also, a “true” SD-WAN often includes a path optimization piece, that constantly monitors all the paths over the Internet backbone between every pair of sites, and adjusts traffic distribution to maximize quality. If one link in the chain goes down, for example, the software defined wide area network system can rejigger the traffic distribution on the fly to find the best QoS for the entire system, and not merely reroute the traffic around the failed link as in standard routing setups.
Needless to say, all this comes with an attendant level of cost and a steep learning curve. To create a “true” SD-WAN, you have to go around the country buying ‘nailed-up’ connections between various Points of Presence (PoPs), and then install policy-based routers that respond to commands from centralized monitoring and control NOCs.
Fortunately, small businesses don’t need all of the complexity and cost of a “true” SD-WAN to realize many benefits. How so? Read on.
SMBs rarely require ‘nailed-up’, QoS-controlled, dedicated connections between sites. Instead, they look for:
So what would be usable for an SMB would be a system that lets them inexpensively realize these benefits without spending an arm and a leg. Enter Uplevel Systems.
Uplevel Systems secure remote worker gateways support an “SMB-friendly” form of SD-WAN technology that is implemented as follows:
This is fairly advanced technology under the hood, marrying together real-time QoS measurements, policy-based routing, automatic tunnel management, etc. But it works, and it provides a number of benefits:

Getting nailed-up MPLS trunks for your very own SD-WAN backbone is, to say the least, expensive. Enterprise-class SD-WAN providers have to pay these costs; so did you realize that with most SD-WAN services, you wind up paying by the megabit? It’s far cheaper to go down to your friendly neighborhood ISP and have them install a second ISP service for your customer.
Plug in the two WAN links, click a few buttons on the dashboard, and voila! It’s set up and running. Once it’s running, the system keeps it monitored, configured, and running.
The “SD-WAN Lite” mode of an operation simply falls back to standard failover if one of the ISP links goes down. Of course, the customer might notice that the service is not quite as stellar as it was with two links, but at least it’s there!
Adding a site? Just drop in a gateway and connect up the two ISP links, and the system automatically reconfigures to bring up and fold in the new office.
SD-WAN is becoming popular, with more companies adopting the services and more SMBs needing the benefits of these services. A conscientious Managed service providers understands the requirements of small businesses and examines what solution can suit their needs well.
Uplevel Systems helps such MSPs provide SMBs with powerful infrastructure credentials and an accomplished team of experts to drive their network needs. With the latest solutions from Uplevel Systems, your business can move off often efficient network management.
Uplevel Systems, as a small business IT infrastructure managed service provider, enables any of these options. Uplevel’s subscription offering is the most popular with SMBs, but some prefer Uplevel’s new equipment purchase program and use a CapEx model.
