Hybrid WAN and SD-WAN Monitoring
Enterprises are increasingly adopting cloud-based services, such as SaaS applications, which in turn increases reliance on the Internet to deliver WAN traffic. Use of traditional MPLS services makes sub-optimal use of costly backhaul WAN bandwidth given that many critical applications and services are no longer internal. As a result, enterprises are migrating to hybrid WAN architectures and SD-WAN technology that combines direct Internet access (DIA), IP VPN tunnels, and traditional MPLS circuits. A robust market of SD-WAN vendors and managed SD-WAN providers has arisen in the last several years to meet this need. Analysts predict that adoption of SD-WAN solutions will become nearly ubiquitous as enterprises refresh their branch office routers over time. An SD-WAN network leverages controllers and orchestration software to optimize hybrid WAN modernization, as orchestration enables automated, near real-time bandwidth management between DIA, backhaul tunnels and MPLS links.
