When migrating a .NET application to Azure, which service allows connection to on-premises SQL databases via Azure ExpressRoute?

Azure App Service
Hybrid Connection Manager
Azure Virtual Network
Azure API Management

The correct answer is: Hybrid Connection Manager

The Hybrid Connection Manager is designed to facilitate seamless connectivity between cloud services and on-premises resources. When migrating a .NET application to Azure, leveraging the Hybrid Connection Manager enables the application to connect to on-premises SQL databases through a secure channel. This tool acts as a bridge, allowing the Azure-based application to communicate with on-premises systems without the need to set up a VPN or a direct connection through other networking solutions. ExpressRoute is a service that provides a direct private connection to Azure, enhancing performance and security. However, while ExpressRoute itself provides connection possibilities, using the Hybrid Connection Manager allows specific applications in Azure App Service to access resources such as SQL databases hosted on-premises efficiently. In contrast, other services mentioned may not directly facilitate the same kind of seamless connection to on-premises databases in this context. Azure API Management is primarily focused on exposing APIs securely, and while Azure App Service also provides a platform to host web applications, it does not inherently include the necessary tools to connect directly to on-premises databases. Azure Virtual Network is essential for establishing networking but requires additional configurations for on-premises connectivity.
