You will inevitably rewrite everything right if you see good growth? This type of architecture stuff is surely over engineering mostly? Im not an engineer but have developed lots of web apps < 1000 users. Maybe outsource anything that requires this type of architecture, e.g. for satellite imagery processing GEE or Sentinel hub. Even then Sentinel Hub just serves from same region as where imagery presides. People are ok with that.
