I have 10 fingers, so that is definitely not "countless" hours of work. And No, Maintenance are minimal or non existent. You could even get smaller VPS behind each node balancer as HA. Since Linode VPS ( Unlike DO ) are deployed on physically different hardware.
While i say it is fair enough to use AWS because money doesn't matter, i thought there are definitely some better alternative for the same price( if you really cared about latency ) or cheaper options.
