Hosting a custom ASP.NET application in a containerized Azure environment can be effectively achieved through Azure Container Instances. This service allows you to run containers in the cloud without managing virtual machines, making it an excellent option for developers who want to deploy applications quickly and scale them in a flexible manner. Azure Container Instances supports various container images and provides a straightforward way to run your application in isolated environments.

This approach is particularly valuable for applications that require easy scaling, quick deployment, and the ability to run in an ephemeral and stateless manner. Container Instances offers a pay-as-you-go pricing model, which is beneficial for applications with variable workloads.

The other options, while useful in their respective contexts, are not primarily designed for containerized applications. Azure SQL Database is focused on relational database services, Azure Web App Service is generally used for web applications without containerization unless utilizing a specific configuration, and Azure Functions is tailored for serverless compute scenarios, which may not align with the needs of a custom ASP.NET application specifically designed to run within container environments.
