Is it possible to host odata webapp inside a cloud service?

I am using a sample odata webapp (eg. ODataSamples\ODataActionsSample). When I click Publish, I only have choices for App Service or Azure VM. I like to use App Service since it can use Azure authentication automatically (via blade setup). However, I want to access my data service which is stored in a Cloud Service.

 

Is it possible to bundle odata webapp in a cloud deploy but retain Azure authentication? I cannot find Azure authentication settings for cloud service (only for app service).

 

Or is it possible to leave odata webapp as a app service purely for the authentication, but redirect to another odata webapp inside cloud service?
