I was seeing on the Cloudflare website that there is the Bandwidth Alliance, which helps reduce network egress costs.
I am moving my services to Google Cloud Platform (App Engine) where I will have nginx servers serving the content and my Cloudflare (Enterprise) account will connect to it to show the data to users.
How do I get the benefits of Bandwith Alliance? Do I need to configure something on my Cloudflare or Google Cloud Platform account?
