MPLS vs SD-WAN
SD-WAN evolved from MPLS technology, which has powered private connectivity for two decades. In many ways, SD-WAN can be seen as a software abstraction of MPLS technology that applies to wider scenarios: It brings secure, private connectivity that's agnostic to all kinds of links and providers and is cloud-aware. While MPLS handles failure scenarios with backup links, SD-WAN handles them with real-time traffic steering based on a centralized policy. Also, since SD-WAN unifies the entire WAN backbone, it delivers comprehensive analytics across the network globally. This wasn't possible before because of disparate pieces of infrastructure and policy.
