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
