 # Authelia
 
 [Authelia](https://github.com/authelia/authelia) is an open-source authentication and authorization server providing 2-factor authentication and single sign-on (SSO) for your applications via a web portal. It acts as a companion of reverse proxies like Nginx, Traefik, or HAProxy to let them know whether queries should pass through. Unauthenticated users are redirected to Authelia Sign-in portal instead.

 # Docker Swarm Mode
 
 For truly highly-available services with Docker containers, we need an orchestration system. Docker Swarm (*as defined at 1.13*) is the simplest way to achieve redundancy, such that a single docker host could be turned off, and none of our services will be interrupted.
