In recent years, a significant number of organizations have transformed their wide area network (WAN). Many of these organizations have some kind of cloud-presence across on-premise data centers and remote site locations.
The vast majority of organizations that I have consulted with have over 10 locations. And it is common to have headquarters in both the US and Europe, along with remote site locations spanning North America, Europe, and Asia.
A WAN transformation project requires this diversity to be taken into consideration when choosing the best SD-WAN vendor to satisfy both; networking and security requirements. Fundamentally, SD-WAN is not just about physical connectivity, there are many more related aspects.
