##  these are the steps I take to create a new fc instance
##  log into aws, launch new AMI instance
##  ssh into machine
##  sudo to root
##  download and run boot.sh (this file -- either from s3 or ssh), this can take 10 minutes
##  NOTE: start.sh usually fails due to env vars, etc..
##  as ec2-user, run start.sh
##  add arbiter db config, and mongo replicated set config, import mongo data using mongorestore command
##    I usually create and grab the latest mongodb backup from S3 (created from existing live server)
##  add dev public keys to /home/ec2-user/.ssh/authorized_keys
##  update /home/ec2-user/.bashrc with AWS env vars
##  add /home/ec2-user/fc/fcbackup/.fcbackup.env (populated with AWS env vars)
##  restart fc app
##  add crontab, using fc/util/crontab-example.txt as example as needed.
##  update cloudwatch monitors for cpu, disk, etc..
##  as root, start epl monitor script in /home/ec2-user/fc/util/start-fc-epl-monitor.sh
##  check app health and switch DNS as desired
