SD-WAN: Guidance on WAN Transformation

SD-WAN: Guidance on WAN Transformation

This IDC study examines how digital transformation and cloud computing are driving the need for significant changes to enterprise WAN architectures, and it provides guidance on how the WAN can be transformed, through adoption of technologies such as hybrid WAN and SD-WAN, to meet a new set of challenges and requirements.“The growing enterprise adoption of SaaS, IaaS, and other cloud services will accelerate and heighten the need for significant architectural changes to the WAN. However, the need for SD-WAN is not only occasioned by the increased adoption of cloud services but also by the steady migration of enterprise data traffic from the enterprise branch directly to the Internet, and by the requirement to reduce the complexity and cost of WAN provisioning and management.”— Brad Casemore, director of research, Datacenter Networking, IDC
