Five Benefits of Managed SD-WAN

Five Benefits of Managed SD-WAN

SD-WAN is well-suited for cloud-centric and hybrid WAN environments. The SD-WAN approach to deploying and managing branch office connectivity is software-enabled and flexible. In an age when much of an organization’s traffic flows from branch offices to the cloud rather than to corporate data centers, SD-WAN taps into all available network resources by dynamically directing traffic across all bandwidth options from MPLS to public broadband connections. SD-WAN provides centralized control and orchestration so that business and application-related policies can be applied to deal with changing network patterns and performance requirements. It also applies techniques such as dynamic path control and adaptive forward error correction and AES 256 encryption to ensure data integrity. It is estimated that by 2018 some 30% of enterprises will use SD-WAN products and services in their branch offices. Another 10% will replace their WAN routing with SD-WAN-based path forwarding, analysts predict.


SD-WAN is available via two deployment models: as a hardware/software solution that IT departments can integrate into their existing infrastructure or as a managed service offered by WAN service providers.

A Managed SD-WAN solution is attractive to IT departments in many ways, including:
  • Implementation and management handled by third party experts
  • Centralized orchestration enables quick service deployment
  • Lock-in to a particular vendor solution is eliminated
  • Connectivity options by location types
  • Transport agnostic


While early proponents of SD-WAN technologies expected companies to replace their traditional WAN solutions entirely with SD-WAN, this has not happened. Companies are looking to reduce bandwidth costs by using broadband Internet. Organizations want to make optimum use of the connectivity they have. And rather than separating private WAN and Internet connections, they want to combine them in a hybrid approach with centralized policy management and resiliency. SD-WAN is not a replacement for existing connectivity solutions but rather a complementary option that delivers price/performance optimization when used in the appropriate environments. There are challenges that IT professionals should be aware of, namely the lack of interoperability standards. There’s also overhead associated with Internet tunneling that can impact network performance. Additionally, upload speeds can be constrained when using SD-WAN solely over broadband Internet. The centralized policy management and zero touch provisioning associated with SD-WAN make it seem like a plug and play solution, but there are considerable setup and deployment issues involved.
