Check out more on my blog at: https://www.mcbeev.com/Blog/April-2019/I-m-Speaking-at-Beer-City-Code-2019 Azure App Services are basically the de facto standard as the best possible way to deploy and host a .Net Framework or .Net Core application, period. You can argue with me until you are blue in the face about other hosting methods or platforms, but you would still be wrong. However, utilizing an Azure App Service as your hosting method is not the same as utilizing standard IIS, especially when it comes to optimization. During the session we will deploy a .Net Core MVC application to Azure, determine an initial baseline for performance, and then walk through how to configure various properties and server-side configurations that make that site blazing fast.
