All digital and network transformation initiatives today are built on the foundation of speed and flexibility. The demand for reliable networking methods has risen dramatically as enterprises large and small throughout the world increasingly digitise in order to enhance operational resiliency.

Most digital transformation programmes have demands and complexities that traditional network architectures were not designed to handle. Worse, business-critical services are frequently dispersed across many clouds and service providers, further jeopardising network performance, particularly at branch sites. The expense of creating and maintaining a private network, particularly for SMEs, can be prohibitively expensive, and adopting older techniques (such as private WANs employing MPLS) can be financially ruinous.
