在ASP之间进行通信的最好方法。NET应用和工人角色

I have both ASP.NET app and Worker Role set up and now I wonder how do I communicate between them? I think that the idea is that the solution will be distributed across different geographic locations. So how do I link the distributed Worker and Web Roles in a simple and efficient way? I have started to look into WCF, but it looks to me to be an overkill and overcomplicated. Another thought I had is to use SignalR client inside the Worker roles to talk with the server in the Web roles.I have both ASP.NET app and Worker Role set up
