SD-WAN is a software-defined approach to managing the Wide Area Network. Times have changed. As businesses adopt the use of SaaS and infrastructure-as-a-service (IaaS) applications in multiple clouds, IT is realizing that the user application experience is poor. That is because WANs designed for a different era are not ready for the unprecedented explosion of WAN traffic that cloud adoption brings. That traffic causes management complexity, application-performance unpredictability, and data vulnerability.
SD-WAN addresses the current IT challenges. This new approach to network connectivity can lower operational costs and improve resource usage for multisite deployments. Network administrators can use bandwidth more efficiently and can help ensure high levels of performance for critical applications without sacrificing security or data privacy.
Reducing costs with transport independence across MPLS, 4G/5G LTE, and other connection types.
Improving application performance and increasing agility.
Optimizing user experience and efficiency for software-as-a-service (SaaS) and public-cloud applications.
Simplifying operations with automation and cloud-based management.
