SD-WAN allows for more agile ways of working and improves site availability through simplified and faster failover and relocation of traffic. It helps optimize costs as once implemented, it allows for better aligned demand and supply model to reduce underutilised assets and increase efficiencies as well as utilise a range of cheaper underlying connectivity.
While it offers benefits of technology-agnostic overlay and dynamic routing, without a clear strategy and transformation plan, many of the SD-WAN benefits can be limited or lost such as the ability to consolidate multiple network functions in a single platform.
