Surfing the Network Transformation Wave: What Drives CIOs to Consider SD-WAN

Feroz Zaveri, Director, Customer Acquisition and Success, APAC, Aryaka Networks | Dec. 6, 2016
Here are the top four crucial reasons why CIOs should consider implementing SD-WAN for their companies/ enterprises.

Cost Reduction: SD-WAN helps businesses save costs compared to MPLS in terms of bandwidth savings. Also, having a global SD-WAN that is fully managed will save the CIOs and their enterprise a significant amount on network maintenance and management costs, freeing IT resources to focus on more business-critical activities.

Network Security: With mission-critical applications moving outside the corporate firewall all the way to the cloud, organisations need to ensure their networks are not only secure, but also adhere to the different compliance standards across geographies. SD-WANs, where the provider owns the network, can offer a multi-layer security model-providing enterprise-grade network security, physical security and access control.

Application Performance: While all the drivers mentioned above are strong indicators of shifting IT priorities, the fundamental role of the network is to deliver reliable and fast application performance. Most SD-WANs today fall short in this area because of their reliance on the public Internet (in the absence of MPLS). The fact that SD-WAN-based hybrid WAN architectures need to rely on MPLS for performance, results in these solutions inheriting the legacy network shortfalls, such as long deployment timelines, high cost, and lack of support for optimised cloud access. Without MPLS, conventional SD-WANs must depend on congested public networks that are prone to delivering frustratingly poor performance due to high packet loss and fluctuating latencies.

In the end, whether in the Cloud or on-premises, mission-critical or peripheral, the performance of your applications and ultimately your business is only as good as your network. While 2016 has certainly been the year where most enterprises have taken a step towards SD-WAN; the year ahead will determine which SD-WAN product is suited for your organization needs that focus on building a wide-area-network for modern enterprise requirements, helping CIOs around the world sleep easy.
