I run my own production server: 11 sites, automations and AI agents behind a single proxy. At NTT DATA, Kubernetes on AWS.
Any visit to a site or a demo. It comes in over HTTPS and resolves through DNS to the server's single proxy.
HTTPS · 11 sites behind one proxy
A wildcard A record points all of *.taller.works at the VPS. Adding a site doesn't touch DNS.
wildcard A · *.taller.works
The server's single reverse proxy. It issues and renews certificates on its own, routes each subdomain to its container and is the only door into the internal network.
automatic TLS · wildcard *.taller.works · 11 virtual hosts · n8n behind the proxy
The Telegram bots call in by webhook. The proxy only accepts those requests when they come from Telegram's IP ranges.
3 bots · IP range filter
Each site is a Compose service enabled by profile: it starts when someone asks for it. Two fit at a time.
Compose profiles · 384 MB per site · max. 2 running
A single database shared by every WordPress site: less memory than one per site.
one instance · backups with wp db export
Tools container for migrations, exports and search-replace without installing anything on the host.
migrations · search-replace
Database export and an uploads tarball per site; restore rewrites URLs with search-replace.
wp db export · uploads tarball · n8n workflows
My control panel: it starts and stops demos by reading Compose labels. Before starting one it checks memory and load, a rule that came from a 12-minute outage.
MAX_RUNNING=2 · ≥ 400 MB free · load < 2
Six flows in production: sign-ups, bookings, bots, reminders and the weekly status. Human approval with Wait + webhook and rate limiting.
