Hi,
It is very nice to see that people in the industry start to understand the revolution that Azure Active Directory Application Proxy brings: http://www.networkworld.com/article/2361973/infrastructure-management/microsoft-azure-service-lets-it-control-identity-and-access-management.html
We see in our dashboards that many of you are already trying it. We see connectors being downloaded and registered, applications being published and on-going usage. Don't hesitate and utilize it as much as you want. Internally, we publish on our test tenants public internet sites like bing.com and our entire team is using the URL that is exposed by the proxy to generate real-world load.
If you haven't already done this, go to your Azure AD tenant and try it by yourself.
