7. WHY A VM ON A CLOUD SERVICE?
   WHY NOT A DEDICATED SERVER? OR A PAAS SERVICE LIKE HEROKU?
   tl;dr-it's a balancing act between advantages of abstraction layers
   Extremely easy setup, trivial scaling, etc.
   Configurability, determinism in performance, etc.
   Services like Azure, EC2, etc., imo, a sweet spot

10. LINUX
    INITIAL SETUP
    After you ssh into your server
    Copy your public key into the authorized_keys file
    Allows you to login to your server with better security than a simple
    password
    But recommended that you password protect your private key
    mkdir ~/.ssh
    vim ~/.ssh/authorized_keys
    chmod go-w ~/.ssh
    chmod 600 ~/.ssh/authorized_keys

    Allows you to search for records
    Think of the database as a giant excel spreadsheet
    that allows you to retrieve information really quickly
