I like the basic technical idea behind Backplane, which is that your backend servers "dial-out" and connect to the edge load balancers. Does anyone know why this technique is not used more? Or is it actually common but I just haven't heard of it? If so who/where is it actually done this way?
I believe Cloudflare offers this as an option: https://www.cloudflare.com/products/argo-tunnel/
