I've worked with several SD-WAN solutions over the past few years, and the product felt more like an automated provisioning tool. Unlike solutions from Palo Alto or other SD-WANs orchestrated by a SaaS solution, Juniper Contrail SD-WAN already had the files and built their SaaS to orchestrate the configuration. Initially, you didn't do much, but then it started adding some routing capabilities. The automation features do help with network operations. Manually configuring SD-WAN is complicated, so the automation simplifies that. However, the initial SD-WAN solution had many limitations, particularly regarding its features. At some point, the tool began looking for other solutions and bought the 128T, which led to implementing a different SD-WAN approach. It also acquired another company for its session smart router, and then it began to develop the exact SD-WAN solution on the Mist Cloud.
