There are many reasons but a few from the top of my head are:
1) The whole system is running on Amazon's Elastic Beanstalk (via Docker). Beanstalk provisions 3 instances for every site (1 Web, 1 Worker/cron, and 1 RDS) for every app with ELB on front.
2) It makes installing updates easy and automatic using deployment scripts which we have on every site.
3) Everything (web/cron/database) is configured to scale up and down automatically, i.e. new servers start as per demand. This may not be possible otherwise.
