Bytell Cloud

Multi-cloud free-tier infrastructure powering services at bytell.com.

What lives where

The stack is intentionally split across providers, each used for its strongest free-tier surface. See Infrastructure overview for the full topology, current status per component, and identity model.

Layer Provider
Always-on compute OCI Phoenix (E2.1.Micro × 2 + Ampere ARM in flight)
Stateless HTTP / serverless containers GCP Cloud Run, fly.io, Render
Edge logic + frontends Cloudflare Workers, Cloudflare Pages
DNS / TLS / tunnels / R2 archive Cloudflare
Postgres (transactional + auth + realtime) Supabase
Postgres (edge-callable + branching) Neon
SQLite at the edge / multi-tenant Turso
Bulk KV OCI NoSQL (pending quota), Cloudflare KV
Cache / rate-limit / TTL state Upstash Redis
Realtime sync Supabase Realtime, GCP Firestore
Event bus GCP Pub/Sub
Analytics + warm logs GCP BigQuery

Why a wide free-tier footprint

This site is part of an experiment in building a meaningful production-shaped stack without a monthly bill. Each provider's always-free quota fills a different niche; together they cover every layer a real product needs. The trade-off is glue — making services across cloud boundaries find each other, authenticate to each other, and ship logs to one place. The Glue page covers the patterns we've adopted and the ones still ahead.
