But in answering this, I wonder if there are actually two use cases here Yes, I see the use cases as the design decision points you are forced to make at varying points in the scale of increasing data volumes: 1) 0-10s of gigabytes: Slam in the RAM on a single server and all is plain sailing 2)

A nice clear post. The choice of Router is obviously key. For the given routing examples based on user or geo it should be possible to map a request to a server. For many other situations it may prove much harder to determine which server has a warm cache because there is no user and there is
