SD-WAN Is Emerging as an Important Driver of Business Results
The increasing need for anywhere, anytime access to applications requires more from enterprise networks than ever before. Distributed enterprises, including those with multiple branches, multiple site types, and remote workers, need to transform their Wide Area Networks (WANs) to service this critical need.
This ongoing transformation is governed by six key principles of today’s business-enabling WAN:
1. Hybrid WAN is common in today’s enterprise
2. WAN connectivity is an essential building block for Digital Transformation (DX)
3. Cloud applications demand more from the WAN than ever before
4. The WAN must become an asset to DX success
5. Adept use of WAN drives positive business results
6. SD-WAN offers new capabilities for enterprise connectivity, and with it come potential benefits
MPLS and Other Technologies Form Increasingly Complex Environments
More and more, enterprises are adding additional communication technologies alongside MPLS to provide interoffice connectivity using hybrid WAN.
MPLS pros: any-to-any routing, class-of-service, performance guarantees
Cons: expensive, complex configuration, long installation lead times
Adept Use of WAN Drives Positive Business Results
Enterprises with mature WAN technology and management (“WAN innovators”) vastly outperform slow movers in WAN technology. These slow movers place great emphasis on cost and security when it comes to WAN technology. While WAN innovators also take security seriously, they place much less emphasis on cost than on key business capabilities like application performance, remote access, and speed to provisioning.
SD-WAN Offers Manageability and Control to Take the Complexity out of Hybrid WAN
SD-WAN is an all-network solution, able to control and manage all the different components combining to provide your network capability, including broadband. Broadband has emerged as an important alternative for today’s enterprise, with cost-effective, secure options available at high bandwidth.
SD-WAN enables new technical capabilities:
The findings in this infobrief derive directly from IDC’s March 2017 study of
For this study IDC surveyed 805 IT and telecom professionals who have strategic insight and knowledge of their enterprise WANs. Qualifying executives worked for U.S. midsize and large companies (with 250 or more employees and at least 10 locations). Respondents came from a mix of industries with emphasis on healthcare, retail, and banking.
