* our data is tiny and fits in RAM
* our data changes often
* we want to eventually get to an HA setup (3-5 etcd nodes now, a handful of backend server instances later)
* we want to be able to do blue/green deploys of our backend control server
* we want tests to run incredibly quickly (our current 8 seconds for all tests is too slow)
* we don't want all engineers to have to install Docker or specific DB versions on their dev machines
