Top Reasons to Employ SD-WAN SD-WAN is a stable, highly scalable, and cost-effective alternative to conventional WANs because it virtualizes endpoints and prioritizes and optimizes connections.

FREMONT, CA: Organizations need quicker, more scalable, and stable Wide-Area Network (WAN) structures as their reliance on cloud-based services and applications grow. The costs and performance problems associated with conventional hardware-based WANs that route all traffic via a central hub are no longer affordable for most businesses.

The Software-Defined Wide-Area Network, or SD-WAN, was created to resolve hardware-based WANs' shortcomings in terms of bandwidth, efficiency, and scalability. SD-WAN is a stable, highly scalable, and cost-effective alternative to conventional WANs because it virtualizes endpoints and prioritizes and optimizes connections. SD-WAN has a range of advantages that, when combined, make it a better option than typical WAN implementations.

Compared to conventional WANs, SD-WAN has many cost advantages. SD-WAN lowers the network's hardware and resources requirements. An SD-WAN reduces IT teams' need to configure and manage additional hardware at the branches thanks to centralized control and virtualized edges.  SD-WAN also saves money by reducing the need for expensive network connections. SD-WAN, in particular, optimizes traffic flow between more expensive MPLS connections and lower-cost broadband connections by using dynamic route selection. As a result, SD-WAN is less expensive than standard MPLS-based WANs.

SD-WAN Improves the Efficiency of Applications And The User Interface

SD-WAN prioritizes traffic based on device priority, giving mission-critical applications precedence over general Internet access, for example. If it is a single branch or a complex multi-cloud network, SD-WAN may evaluate different routes' efficiency in real-time and allocate resources accordingly. This instance solves many of the problems that conventional WANs have with network congestion, allowing priority applications to perform better.

SD-WAN Allows for More Scalability

Since the edges are virtualized, SD-WAN is more scalable than conventional WANs. In a traditional WAN, increasing the number of endpoints or facilities will necessitate significant hardware investments. In comparison, SD-WAN enables an enterprise to easily and cost-effectively incorporate new branches, applications, and services. SD-WAN can also help with scaling in multi-cloud environments.
