You don&#x27;t need to run your own server to use Let&#x27;s Encrypt.  You probably do want some sort of automated method for updating the cert due to the low expiration time (though it isn&#x27;t mandatory), but that can be done in many ways such as a desktop application, or just having the shared hosting service add built-in support for Let&#x27;s Encrypt, as Dreamhost has already done.
