One of the most important steps towards digital transformation is the move to Software-Defined Orchestration. In networking, Software-Defined Wide Area Network (SD-WAN) is becoming a strong contender for managing enterprise networks. Cato Networks’ “State of WAN 2018: Too Complex to Ignore” report predicts SD-WAN will grow 200% year-over-year. Unlike legacy WAN technologies, SD-WAN can offer the programmability, automation and orchestration to enable innovation and accelerate growth.

You might be wondering why your customers might need SD-WAN when their current WAN architecture works perfectly fine. How good is good enough? What are the benefits of SD-WAN and how can it be tailored to their organisation’s network needs? At the crossroads, these might be some of the reasons why your customers should consider embracing SD-WAN…

#1 Increasing Need for Network Performance

The rise of Cloud, Big Data and IoT has driven demands for greater speed in the delivery of services. Enterprises must adapt quickly to meet the changing needs of consumers while ensuring quality performance of their Cloud-based applications. These business-critical applications that cannot afford any jitter or packet loss.

The programmability of SD-WAN offers greater control and orchestration to guarantee the most suitable path with minimum latency and adequate bandwidth. It also provides real-time monitoring of the network to prevent congestion and uses automation to intelligently route traffic based on policy.
#2 Increased Costs for Growing Bandwidth Volumes
Bandwidth demand is growing rapidly with the adoption of Cloud-based applications and consumption of digital contents. Many enterprises today still depend on MPLS for their bandwidth requirements. While it can be highly reliable and offers guaranteed quality of service, high-bandwidth MPLS services are very expensive.
Cost-savings with SD-WAN is real. Unlike MPLS, SD-WAN can add new links without making changes to the network or infrastructure and uses less expensive connectivity such as internet broadband or Ethernet. Gartner analyst Andrew Lerner estimates that an SD-WAN can be up to two and a half times less expensive than a traditional WAN architecture.
#3 The Need to Scale Up Quickly
The world is changing faster than ever. Most enterprises understand the need to adapt quickly and are constantly looking for new models to enhance business agility. Across the ecosystem, there is a realisation that the network cannot be a bottleneck for innovation.
To mirror the speed and agility of the Cloud, SD-WAN lowers the complexity of connecting enterprise networks and reduces time to deploy new services. By delivering SD-WAN through the Cloud, enterprises can gain increased flexibility that allows them to scale connectivity up or down to suit their business needs.
#4 Worried About Security
Network is the lifeblood of many enterprises today. It keeps the business operations running and enables staff to be productive, especially those working remotely. Security can be extremely challenging for enterprises that need to connect multiple offices. If the network is compromised, everything will grind to a halt.
Traditional WANs were not designed to secure distributed network architecture and Cloud-based applications. Instead of managing physical appliances at multiple branch locations, SD-WAN presents new security capabilities such as a full network security stack without the need to deploy security appliances, backhaul traffic or introduce new security services.
