Transitioning to SD-WAN for Cloud Connectivity

This technical report discusses the transition from traditional hub-and-spoke WAN architectures to Software-Defined Wide Area Networking (SD-WAN) as a solution for modern networking challenges. It outlines the inefficiencies of conventional models, particularly in the context of increasing cloud service adoption and the resultant rise in Internet-bound traffic. The document details how SD-WAN enables more efficient routing by allowing local breakout of Internet traffic, thus enhancing user experience and network performance. It further explains the role of SD-WAN virtual appliances in establishing secure connections to cloud services, ensuring that user traffic is routed through private VPN tunnels rather than the public internet. The report includes case studies from organizations such as Centric Health, Cpl, and St. Francis Credit Union, illustrating the practical benefits of SD-WAN in improving network efficiency, scalability, and security. These examples highlight how SD-WAN has become integral to cloud migration strategies for various businesses.
