SD-WAN lays the groundwork for SASE 

As applications move to the cloud, enterprises need a network that can keep up. To address the application performance issues of traditional wide area networks, a software-defined wide area network (SD-WAN) provides simplified and flexible deployment options, improved application performance, security, and complete visibility at the network edge.

SD-WAN solutions streamline management and deliver cost savings to the enterprise. They provide the foundation for cloud connectivity and modern operational models, allowing IT to deliver a new level of enterprise-wide service and user experience. This paper explains: 

• How traditional WAN evolved into SD-WAN

• How VMware SD-WAN™ simplifies WAN deployment with a cloud-delivered model

• The different stages of WAN transformation that lead to SASE

This white paper is part of a series adapted and updated from the book Journey into the World of SASE, by VMware technical product managers Rohan Naggi and Ferdinand Sales (VMware Press, April 2021). We’ve broken the book into shorter, easier-to-consume papers. Whether you read individual papers or the whole book, the goal is to help you understand your company’s journey to SASE: why SASE is important, how it works, and what you need to know to implement it successfully.
