## Architecture
![Architecture behind mdleom.com](about/website-architecture.png)
2021-02-24 02:14:57 +00:00
mdleom.com is served from two identical VMs hosted in a cloud provider. The VMs are using [NixOS](https://nixos.org/) and [Caddy](https://caddyserver.com/) 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](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/deploy-cloudflared-replicas/) that connects to the same tunnel to provide failover.
2024-10-04 22:49:22 +00:00
The web server is able to failover to mirrors ([Cloudflare Pages](https://curben.pages.dev), [Netlify](https://curben.netlify.app), [GitLab Pages](https://curben.gitlab.io) and [GitHub Pages](https://curbengh.github.io)). Blog content is deployed from a [GitLab repository](https://gitlab.com/curben/blog) which hosts the source. The source is compiled to static site using [Hexo](https://hexo.io). The repo also hosts [images and attachments](https://gitlab.com/curben/blog/-/tree/site), images are resized on-the-fly using [Cloudflare Images](https://gitlab.com/curben/blog/-/blob/master/cf-images/index.js). [microblog](/microblog/) source is hosted on the [`microblog`](https://gitlab.com/curben/blog/-/tree/microblog) branch.
