SDWAN also has a place in a Multi Cloud architecture. It is easier to deploy SDWAN if you’re only connecting a few sites but when you reach a certain threshold, the number of subscriptions you need to purchase, and costs will increase.
However, SD WAN is fantastic for bonding cheap links together and providing QoS and Failover across lower cost links. Cloud Solutions Group works with the best of breed SD-WAN vendors which have solutions that integrate with the Public Clouds both for SaaS and IaaS as well as vendors from which you can consume SD WAN as a Service.
