If you’re an IT manager, you’re likely interested in SD-WAN topics. After all, it’s a fast-growing market. You can expect to see more SD-WAN offerings over the next few years, which means more opportunities for WTG channel partners. In fact, 90% of network managers plan to upgrade to SD-WAN technology. If you don’t have the time to attend an SD-WAN conference, you can find on-demand webinars to answer the most pressing questions about the SD-WAN technology and provide in-depth insight into various SD-WAN topics.
For IT pros interested in SD-WAN, there are some topics that must be understood before taking an SD-WAN exam. These include SD-WAN hardware platforms, SD-WAN APIs, and Cisco IOS-XE and “Viptela” code. The book also includes chapter quizzes, which act as practice exams for the ENSDWI exam. This textbook is highly recommended, and will give you a solid grounding in the fundamentals of SD-WAN.
While SD-WAN is an emerging technology, the process of setting it up is very similar to traditional branch routers. Instead of using branch routers, SD-WAN routes traffic to remote locations using centralized management and policy control. A good example of this is the ability to manage total transport outages with sub-second failover. In this way, the outage will not interrupt business-critical applications. Further, SD-WAN extends software-defined networking concepts to WANs.
With SD-WAN, the network layer has evolved with the integration of major cloud providers, Secure Access Service Edge (SASE), and application-aware routing (AAR). These new features provide the ultimate in application diversity and performance. They also give users the opportunity to work securely from anywhere. IT teams must carefully analyze the user workflow and document the business application flows. With SD-WAN, you’ll be able to track and measure productivity gains and efficiency.
