Before implementing SD-WAN, it is crucial to identify and understand the organization’s needs and its role in business strategy. The following use cases highlight the diverse applications of SD-WAN, tailored to specific business environments and objectives. Understanding how SD-WAN can benefit your business and customers is key.

1. Direct Internet Access (DIA)

Integrated cloud-based security can effectively guard against internet threats. With Dedicated Internet Access, you can offload bandwidth from the WAN, enhance security, and accelerate internet access for branch employees and visitors. DIA allows local connections for branch employees and customers, reducing WAN traffic and boosting internet speed. This not only saves time and money but also improves overall network efficiency.

While SD-WAN primarily relies on software, it still requires hardware devices such as SD-WAN routers to operate. Unlike traditional WANs, SD-WAN devices (e.g., those provided by Cisco) are often plug-and-play, reducing the need for management intervention at branch locations.

2. Branch-to-Branch Connectivity

Organizations requiring high-throughput, continuous connections between multiple offices traditionally rely on MPLS circuits or VPN tunnels. MPLS routes data by identifying existing paths between endpoints, while VPNs encrypt data over public networks.

SD-WAN simplifies branch-to-branch connectivity, reducing management complexity and costs. With centralized control and automation, SD-WAN users can easily connect to virtual locations, eliminating bottlenecks and enhancing application performance.

3. Application Performance Optimization

SD-WAN helps network administrators define Service Level Agreements (SLAs) that meet business needs, such as setting parameters for uptime, repair time, and latency. By effectively routing traffic to meet these SLAs, SD-WAN alleviates network congestion, improves application performance, and reduces network costs.

Post-installation, applications no longer need to be rerouted through a central site. SD-WAN enables administrators to prioritize mission-critical applications and route traffic using the best available transmission method. For example, SD-WAN devices can be configured to prioritize voice traffic (such as VoIP), ensuring a smooth call experience.

4. Cloud Migration

SD-WAN supports superior branch and cloud connectivity, application prioritization, and improved network traffic visibility, making it an ideal choice for implementing a cloud-first strategy.

Traditional WANs only support applications from a central data center, whereas SD-WAN meets the stringent demands of cloud computing. It supports direct cloud access for all applications, application-based routing, direct internet access for branches, and provides visibility and simplified management.
