Reading this article, and specially this paragraph:
The SKU and Scale of the App Service plan determines the cost and not the number of apps hosted in it.
Can I create as many Web Apps as I need into the same resource group with the same App Service Plan?
For instance, I have a RG named S1-Resources and a S1 App Service Plan. If I create for instance 3 Web Apps into that RG linking them to the App Service, Will I be charged $0.10/hr for each Web App?
