A bit OT, but do you mean the servers for AppGet?

Yeah, there is quite a bit of background infrastructure to allow checking for installed app updates, search, and automatically updating package manifests when a developer releases an update.

Are you using an App Service, and is the infrastructure documented publicly?

I'm an architect, so just keen to understand your architecture on the backend :)

I wrote a brief description a while back here, https://github.com/appget/appget/issues/24#issuecomment-4648...

after all this is over, I'll probably do a write up of hall it all worked behind the scene + all the server code.
