Enterprise business requirements are getting increasingly complex in today's digital era. Customers, both internal and external, expect their requirements to be addressed quickly while maintaining a high level of user experience. This adoption of 3rd Platform technologies is placing unprecedented pressure on legacy networks, elevating the network's end-to-end importance to business operations. As organizations move to a software-defined architecture to address these network challenges, they can learn a lot from each other's network transformation journeys and avoid common pitfalls in migration to SD-WAN. We highlight some of those key learnings in this document. "Networks play a critical role in meeting the transformative demands of a evolving digital enterprise. As legacy WANs struggle to keep up with evolving workloads and moving to cloud, SD-WAN adds a new tool to the network manager's toolkit, bringing flexibility and control to static and inflexible networks. However, organizations must realize that this network transformation is not a straightforward. Hence, they should keep various pitfalls in mind and carefully select their network transformation partner," says Nikhil Batra, associate research director, Asia/Pacific Telecom and Internet of Things Practice.
