Our business has an API that can be used for displaying dynamic information at point of sale (i.e. dynamic in that it cannot be cached and will need a DB call).

While we encourage our customers to try and use us asynchronously, we have a number of enterprises that don't and therefore demand incredibly fast response times with low latency. They pay us accordingly, so as a result we have geolocated databases (in our case though, we are using AWS Aurora replication).
