I plan to replace Azure cloud services’ provided subdomain (myapp.cloudapp.net) with our own domain, customDomain.com. I eventually find out that I cannot do that. I have to configure a custom domain name to route traffic to myapp.cloudapp.net. Why does not Azure allow me to replace myapp.cloudapp.net with my own custom domain? I end up having two domains for one site. Please look at this site:
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-custom-domain-name/
That custom domain name also has an SSL certificate from a CA. In addition to that, I also use single sign on for my application (Identity and Access). In this case, I configure the Identity and Access (realm of my application) with my custom domain name. Is this the right way? It does not make sense to configure this with myapp.cloudapp.net. I currently have issues with ADFS but I could not figure out why.
