The WAN, or Wide Area Network architecture, that most businesses use was implemented decades ago for the delivery of client/server and best-effort internet traffic.
Today with massive advancements in technology, cloud, mobility, unified communications, and the Internet of Things (IoT), WAN is now one of the fastest-growing application types. It drives significantly different traffic patterns compared to those just a decade ago.
The traditional network architecture is slowly becoming obsolete due to the following seven challenges:
- Slow network operations
- Unnecessary network outages
- Inefficient use of bandwidth
- Changing traffic patterns
- Video applications
- Encrypted traffic
- Business use of broadband
As businesses become more dynamic and distributed, wide area networks will be seen as more of a strategic resource and not just a tactical one.
To completely harness the power of digital transformation, organizational networks will evolve from WAN architecture to SD-WANs or software-defined wide-area networks.
