Huddle01 vs Fly.io: Which Platform Handles Blockchain Node Hosting Better?
Deployment Anatomy: Validator & RPC Node Clusters on Huddle01 and Fly.io
Recommended infrastructure and deployment flow optimized for reliability, scale, and operational clarity.

Deployment Flow
Spin up Huddle01 VMs in the region closest to your main userbase e.g., Mumbai for Indian dApps or validators. Request NVMe-local disk for archive nodes. On Fly.io, deploy an app with attached persistent volume in your target edge city.
Containerize the blockchain node using your usual Dockerfile. Avoid heavy systemd; use s6 or tini for restarts. Bind volumes for chain data (~800 GB-2 TB for full/archival nodes).
Wire up network security. On Huddle01: map VLANs for each cluster, assign static IPs, and set up real inbound firewalling. On Fly.io: set Wireguard keys for each instance, enforce access policies note, firewalls operate over their mesh, which can get confusing if instances migrate.
Start the chain node with a seed peer set (especially for state sync). If you’re using distributed validators, configure consensus keys to avoid double signing. This bites more teams than it should.
Integrate metrics exporters Prometheus for node state, custom scripts for syncing lag. If you’re on Fly.io, watch read/write IO like a hawk network disk stalls, especially during reindex.
Test simulated failure: power cycle VMs, nuke network links, observe container restart time and block replay windows. On Huddle01, cold reload from NVMe is <4 hours for ~1.2TB Polygon arch. On Fly.io, expect 8-12 hours for same reindex due to networked disk and possible mesh handshake slowness.
Trigger alerting hooks (UptimeRobot or Healthchecks.io endpoints). At true fault, check network plumbing first on Fly.io mesh gets funky if neighboring edge is degraded. On Huddle01, it's almost always disk/VM or peering config.
Monitor cost in-flight. On heavy RPC output, tally egress per day. On Fly.io, after 1.5 TB/month, costs can tip. Huddle01’s zero egress means flat bills regardless (unless physical move needed).
