Many organizations with traditional WAN architectures have insufficient bandwidth and can no longer cost-effectively provide reliable and secure high-speed connections to their data center or cloud-based applications. These enterprises typically deploy dedicated links, like MPLS, from network service providers, but the rapid growth in WAN traffic has prompted these organizations to find less expensive options.
To help improve traffic handling and application performance, organizations are turning to software-defined WAN. SD-WAN products can improve bandwidth, help prioritize traffic for critical applications and offer significant operational benefits. SD-WAN uses software to combine multiple network sites into one logical network, and it hides the physical network with a virtual network overlay.
An organization's requirements for SD-WAN depend on its size, location and vertical industry. Organizations with a large number of remote employees and numerous branch offices -- such as financial services, restaurants, retail, healthcare, manufacturing and government -- can undergo major SD-WAN deployments.
Before selecting an SD-WAN vendor, it's crucial to carefully evaluate your branch networking requirements and determine what problem you're trying to solve. This information can help you make a compelling business case to management. For example, is your organization experiencing poor WAN connection reliability with a specific application? Or, does your network face a more general issue with WAN bandwidth, such as outages that affect the networking group's productivity?
This buyer's guide is designed to help reduce the guesswork of selecting an SD-WAN approach. By examining the features and functions of leading SD-WAN products and matching those to your organization's requirements, you can choose the offering that will best suit your needs.
