The contemporary business environment uses cloud applications, distributed work environments, working from home and a variety of network connections, and as a result, managing traditional WAN topologies becomes more difficult. With SD-WAN, this is made easier due to the use of software-defined policies for traffic optimization over broadband, MPLS, LTE and 5G network services.
Different SD-WAN suppliers have different focuses – some of them concentrate on security integration, cloud connectivity, SASE, application performance, automation and managed network solutions. The choice of the appropriate solution depends on the size of the corporate network, cloud usage, security demands, and application needs.
What Should Businesses Look for in SD-WAN Products?
When selecting an SD-WAN vendor, businesses need to understand how compatible the selected product will be with their existing infrastructure and future needs. Among the aspects that are worth considering are application-aware routing, management capabilities, automation, traffic visibility, failover, multi-WAN support, cloud connectivity, security, scalability, and analytics.
Companies may have different preferences regarding the management style – they may opt for self-managed solutions, managed SD-WAN, or hybrid. As stated by IBM, SD-WAN allows centralizing the management process among different WANs and optimizing traffic depending on application and network specifics.
Below you can find some vendors offering different options for SD-WAN.
