In this model, you build stateless web apps such as ASP.NET and Node.js and deploy your application's frontend as stateless Reliable Services. The Front End can communicate with Stateless Middle-tier Compute using Queue in case asynchronous processing is desired or using HTTP protocol in case synchronous communication is desired. The middle-tier is built using stateless web framework such as Web API or can execute as a continuously executing process. The model can be seen in the following image:
