Architecture

mdleom.com is served from two identical VMs hosted in a cloud provider. The VMs are using NixOS and Caddy web server. The web server functions as a file server to serve static website. Each VM has cloudflared to connect the web server to Cloudflare CDN using an outbound tunnel. Each cloudflared instance acts as a replica that connects to the same tunnel to provide failover.

The web server is able to failover to mirrors (Cloudflare Pages, Netlify, GitLab Pages and GitHub Pages). Blog content is deployed from a GitLab repository which hosts the source. The source is compiled to static site using Hexo. The repo also hosts images and attachments; images are resized on-the-fly using Statically.

More details are available in the following series of posts:
