What is SD-WAN and Why Are So Many Companies Looking into This?

What is SD-WAN?

Software-defined WANs are quickly replacing traditional Wide Area Networks (WANs) as more enterprises realize the need to rethink networking for today’s cloud-centric world.

Today’s SD-WANs are providing organizations: Lower costs by eliminating reliance on expensive MPLS connections to interconnect remote sites Higher performance by leveraging multiple network paths and faster broadband connections for certain applications including cloud Increased network agility by decreasing manual configuration steps through increased programmability and automation. Deploying SD-WAN ensures your wide-area network is future-proof for cloud computing and can adapt to rapidly changing application and business requirements.

The benefits of SD-WAN include cost-effective delivery of business applications, meeting the evolving operational requirements of the modern branch/remote site, optimizing software-as-a-service (SaaS) and cloud-based services such as UC&C, and improving branch-IT efficiency through automation. "As public and private cloud use continues to grow, WAN performance becomes critical to latency-sensitive and mission-critical workloads and inter-datacenter business continuity," said Rohit Mehra, Vice President, Network Infrastructure at IDC. "Accordingly, as enterprises plan and implement comprehensive cloud strategies, WAN architectures need to be considered alongside, and in conjunction with, datacenter infrastructure.

Moreover, as enterprises move business processes to the cloud, there is a greater need to fully integrate cloud-sourced services into WAN environments to ensure workload/application performance, availability, and security."
