SD-WAN network

Posted by aylin on January 16th, 2020

SD-WAN network is a software-defined approach to managing the wide-area network, or WAN.

Key advantages include:

  • Reducing costs with transport independence across MPLS, 3G/4G LTE, etc.
  • Improving business application performance and increasing agility.
  • Optimizing the user experience and efficiency for SaaS and public cloud applications.
  • Simplifying operations with automation and cloud-based management.

Times have changed. As businesses race to adopt the use of SaaS/IaaS applications in multiple clouds, IT is realizing that the user application experience is poor. That is because WAN networks 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.

Further opening the enterprise to the Internet and the cloud exposes major threat and compliance issues. It is extremely challenging to protect the critical assets of an enterprise when applications are accessed by a diverse workforce, whose role access ranges from employee to partner, contractor, vendor, and guest. Enabling broadband in the WAN makes the security requirements more acute, creating challenges for IT in balancing the user experience, security, and complexity.
