Why should you upgrade to a VPS or Dedicated Server? This may have to do with the type of site you have. If you have a lot of photos and videos that are password protected, this may be against your host’s rules for shared accounts which often prohibit file storage. Or you have a lot of site visitors, the metaphorical guests in your apartment, and your account may start getting crowded as those guests start clogging up the “hallways” otherwise known as CPU capacity. Another reason is to have full control over the configuration of your server, if you own a house you can make modifications you may not be allowed to make in an apartment or townhome.
