This talk shows how with the right configuration and some open source, a Software-Defined Wide Area Network (SD-WAN) can automagically optimize the Egress traffic of a Service Mesh. Using the 'Cloud Native SD-WAN' open-source project, Egress configuration from Service Meshes can now be used to program SD-WAN optimizations towards remote external services.This leverages the 'SaaS optimization' feature offered by several SD-WAN solutions. SaaS optimization enhances connectivity towards SaaS applications (either public SaaS or user-defined remote applications) by constantly probing the remote application from different points of the SD-WAN network to continually compute the best path to reach it.On the Service Mesh side, Egress configurations are used to learn which external services should be probed (and how) to get their traffic optimized. What is typically used to enforce security policies (e.g. allow/deny) can be transposed into traffic engineering optimizations on the SD-WAN.Click here to view captioning/translation in the MeetingPlay platform!
