An ASE provides a dedicated and isolated environment to run Azure App Service. ASE is a premium service offered in Microsoft Azure. It provides more instances to scale if Azure Web Apps is hosted in an ASE. In Azure Web Apps, we have a Networking section where we can integrate Azure Web Apps with Azure VNet. In ASE, we can host Azure Web Apps in the VNet itself. In other words, ASE can be created in the subnet of a VNet as they are deployed in a VNet created by the account owner.
The benefit of hosting Azure App Service or Azure Web Apps in the ASE is that we can configure security for Azure Web Apps the way we do it for Azure VNet. In simple terms, we can use Network Security Groups (NSGs) to make it more secure. We can create NSGs with inbound and outbound rules to control traffic to Azure Web Apps. Thus, we can create a hybrid cloud scenario where Azure Web Apps can communicate with on-premise resources over a secure connection.
