Unlike traditional WANs, SD-WAN delivers increased network agility and cost reduction. Software-Defined WAN has its roots in Software-Defined Networking (SDN), the underlying principle of which is to abstract the network hardware and transport characteristics from the applications that use the network.
According to a recent IDC report, 73% of Canadian organizations have migrated at least some of their IT delivery to the Cloud. This rapid adoption of public and private clouds and SaaS-based applications has created a demand for increased bandwidth.
Canadian businesses rely heavily on hardware-centric legacy technologies like MPLS, Private lines and broadband solutions like DSL and Cable for connectivity. The rigidity of the traditional infrastructure makes it cost-prohibitive for mass adoption, especially by the smaller enterprise to mid-sized companies. Additionally, the complexity involved in managing traditional WAN solutions makes it unsuitable for larger organizations to manage their growing demands for higher bandwidth, speed and reliability. This is where SD-WAN excels and has grown in popularity.
