Think about switching to Balrog for our server side Tor Browser update components
While discussing #19890 (moved) with Mozilla engineers we came across the topic on how we handle our server-side update part. It turns out that they basically did back then what we are doing now. They recommended to look at Balrog once we believe our needs do not scale anymore/or the system feels like being messed up etc. See: http://wiki.mozilla.org/Balrog for details.
