Businesses and their IT teams face three major challenges:
Increased access cost for MPLS-based bandwidth to support application performance
High complexity in branch deployments
Architectural issues with traditional WAN that is both static and private, inhibiting the migration to dynamic and public cloud environments.
Benefit of SD-WAN
Business agility. Rapid deployment of WAN services (suchas bandwidth and firewall) to distributed branch operationswithout the need to send IT personnel on-site. Bandwidthcan be easily added (with additional circuits) or reduced asbusiness requirements evolve.
Internet economics. Internet connectivity (including cable,DSL and ethernet) is widely available, quick to deploy and afraction of the cost of equivalent MPLS circuits. SD-WANprovides the benefits of reliable, secure WAN service atInternet price points.
Optimized cloud architecture. SD-WAN eliminates thebackhaul penalties of traditional MPLS networks and leveragesthe Internet to provide secure, high-performance connections from the branch to cloud. With SD-WAN, remote users will seesignificant improvements in their experience when using thecloud/SaaS-based applications.
