For years, Multiprotocol Label Switching (MPLS) networks have been connecting organizations with their remote locations. The stability, performance and scalability of MPLS has always been appealing. The price tag? Not so much. Internet connectivity has always been much cheaper and more flexible than MPLS, but concerns about security and performance have prevented organizations from making changes to the wide-area network (WAN) – until recently.
Widespread adoption of cloud-based service and applications has resulted in a large portion of traffic traveling back and forth across broadband Internet connections. Cloud environments are often more secure than on-premises IT environments, and technological advances have minimized performance issues. As a result, many organizations have decided that if the Internet is good enough for many business applications, it’s good enough for the WAN.
