We use SSL certificates from AWS Certificate Manager. These certificates are not downloaded as files and deployed on the servers like other SSL's. We use them with AWS Elastic Load Balancers (ELB). We use the ELB's in place of the ArcGIS Web Adapter.
I am now planning a deployment of Portal. My deployment will require using the ArcGIS Web Adapter to support Roads & Highways. I'm curious if there is a way to continue using my AWS SSL's and ELB's as well as the Web Adapter? If not, I imagine I will have to go buy an SSL certificate from a different provider to put on my Portal machine. Thoughts about AWS ELB's and the ArcGIS Web Adapter co-existing?
