ABSTRACT
Public Internet has the advantages of being cost effective, bandwidth scalable, and ubiquitously available; meanwhile, Software-defined wide-area network (SD-WAN) is capable of overcoming the security, reliability, and performance challenges to using the public Internet for business applications. For an enterprise that has a bigger wide-area network footprint, the more savings it may reap from SD-WAN. For small and medium sized business, SD-WAN enables them to effectively run most of their applications and daily operations from the Cloud.SD-WAN technology has the ability to recognize all applications and configure them according to business requirements. A big benefit of SD-WAN is the ability to increase segmentation, where each segment can have a different topology, thus increasing security in the network. SD-WAN can bring up more enhanced and cost-effective security measures and defense for enterprises, especially for their formerly vulnerable branch offices. One big advantage is SD-WAN offers a holistic visibility into the amount and types of traffic traversing the network.
