Multiprotocol layer switching (MPLS) networks have, for decades, been the gold standard for businesses that need wide-area network connectivity between several different locations. But due to their age, they have difficulty integrating with newer technologies such as cloud computing. They’re also notoriously expensive and difficult to configure. An increasingly popular alternative to MPLS is software-defined wide area networks (SD-WANs). As the name suggests, they’re a type of WAN that’s controlled via intelligent software. In addition to being far easier to implement with cloud computing, they’re often less expensive. They’re also far easier to configure, as every endpoint device on a network is unified by the software interface: Make a change in the software, and it can be automatically applied to all other networking hardware.
