Enterprises have long relied on multiprotocol label switching (MPLS) services or IPSec VPNs over broadband Internet to build wide area networks (WANs). Both of these methods have always had their challenges and were designed for a world where apps lived in a private data center and users were mostly in offices.
Fast forward to the present day — with more data-rich applications, more applications running in the cloud, and entire workforces enabled to work from home — and we see conventional WANs struggling to keep up.
Read this whitepaper to learn more about the challenges with traditional WAN architecture and how WAN-as-a-Service meets the demands of modern networks.
