The AzureDistributedService library provides a framework for making remote procedure calls (RPC) from front-end clients (WebRoles/WebSites) to back-end VMs (WorkerRoles) using Azure Storage Queues. The system is easy to set-up and the calls look like simple RPC calls. The system internally uses .NET 4.5+ async-await pattern to allow even a pair Extra Small front-end VMs to handle hundreds of simultaneous requests. And because the front-end communicates with the back-end through an Azure Storage Queue, the worker VMs can be auto-scaled trivially using Azure's built in auto-scaling.
