I saw Mike Benkovich speak on blueprints in the Azure space at the Minnesota Developers Conference.

@config["FavoriteColor"] might be, in Razor markup, the way to pull something directly from appsettings.json. I've never needed to do this before but this showed up in one of Mike's examples. He made on the fly an MVC application and then went on to discuss how FavoriteColor in appsettings.json could be changed out from the Azure side. A blueprint in Azure is a collection of resource groups, policies, role-based access controls (RBAC), and templates. Blueprints in Azure allow you to create starting spots for an app with some of the stuff you know you are going to want already baked out. SWIFT CSP stands for the Society for Worldwide Interbank Financial Telecommunication and Customer Security Programme respectively. A personal access token is referred to as a PAT token. This is some of the stuff you might preconfigure. You may version blueprints. At Application Insights (analytics) you may have key values in the cloud and you may change out the app settings in the cloud to point into app settings for an App Service. A resource group object in an App Service will make an app setting override the app setting in the appsettings.json file and there you are. The Azure Resource Manager or ARM lets you deploy stuff in Azure and ARM speaks ReST natively.
