Driving success of SD-WAN transitions requires significant investment from IT in both time and effort. See what 451 Research Analyst Mike Fratto suggests when it comes to monitoring SD-WAN transformations.

As businesses continue to seek alternatives to expensive and often inflexible MPLS network architectures, software-defined WAN (SD-WAN) continues to show value as a key technology for managing application and network load over multiple connections. It’s particularly good for businesses with a large number of remote locations that mix cloud proxy traffic or data center traffic with direct internet access (DIA). Based on our recommended monitoring deployment, AppNeta can provide application context to what end users experience over your SD-WAN connection and over each bonded provider as well as provide 3rd-party validation for your SD-WAN deployment.
Organizations are deploying SD-WAN to pair multiple cheaper public internet connections, or pair a public internet connection with existing MPLS connectivity, to lower costs and add network reliability. SD-WAN isn’t new—load balancers for multiple internet connections have existed for some time. But SD-WAN technology allows IT Ops groups to centralize control of traffic routing across these multiple connections. You can send VoIP and other critical application traffic over a higher-quality connection, while moving recreational application usage to a lower-QoS connection. Cloud proxies can verify unknown traffic and known, trusted traffic can be routed over DIA. There are multiple ways to architect an SD-WAN deployment, but SD-WAN is focused on just that—the WAN. To get true end-to-end insight including WiFi, LAN, and your network infrastructure you need a comprehensive approach to validating and monitoring that your deployment is effective.

Find missing application performance information
While SD-WAN technology can help improve the reliability of connectivity, it provides limited information on the performance of applications across the wire. While SD-WAN can tell you that Connection A is operating faster than Connection B, it cannot tell you if the performance of your Point of Sale application is poor. Or that your network is unable to support VoIP. Or that the performance of your application over WiFi has degraded due to WAN connectivity.
As a power user of an SD-WAN solution, I can see how AppNeta adds real value.

How AppNeta Monitors SD-WAN
AppNeta lets you contextualize application performance with your SD-WAN deployment. By monitoring both apps and the network paths they are traversing, AppNeta shows you the real-time status and performance of the dynamic routing your SD-WAN provides. This comes in handy in a few particular situations.
AppNeta monitors through and around your SD-WAN provider to provide a real-time comparison
By design, your users see applications, not the complex, dynamic routes that deliver them. Seeing the end-to-end performance from their perspective is crucial to keep IT aware of their experience and improve response time when issues arise. AppNeta provides the real-time performance information you need to understand what is happening on the network. Based on our recommended deployment, AppNeta can provide visibility into the applications in use at each location and the connection that they are being delivered over. While some visibility is dependent on the setup and your SD-WAN vendor we can ensure complete visibility for every location with Usage.
If you’re relying on multiple ISP connections to serve employee or customer locations, you’re likely not getting the real-time visibility into what network you’re using. AppNeta can monitor traffic over specific links as well as send traffic through the SD-WAN logic. You can benchmark and compare your services for SLA validation, issue mitigation and proactive alerting. AppNeta offers comprehensive SD-WAN monitoring with the Small Office Monitoring Point.
SD-WAN functionality usually stops once it gets to your WiFi router. In retail spaces, many companies are deploying public WiFi as a benefit for their customers and to serve in-store offers and understand consumer foot traffic. In this new retail world, WiFi for the customers moves from being a cost center to being a source of revenue. It’s critical to provide fantastic network performance to keep customers on the WiFi while in store.
