a newbie question. I've done plenty Java dev (e.g. GAE) and mobile dev such as iOS and Android. I am investigating Windows Azure as the platform for our server-side services that our mobile devices interact with. I have to admit I have a hard time getting my head around it. Part of it is acronym-overload. Are there any good pointers how the various acronyms glue together? 

I've worked through some of the tutorials but they mostly focus on doing a web site in Azure. In our case, there really aren't any web pages but rather services (some REST, some otherwise) that the devices call into. To come perhaps to a specific question: how does a worker role, or a web role, retrieve the content of an http-post sent to the endpoint I created for it?
