Deploy Hermes 24/7 on a $5 VPS

A cheap VPS is viable if you keep the footprint boring

A $5 VPS will not forgive waste. The deployment works when the service stays simple: one process manager, one reverse proxy, constrained logs, and no unnecessary background jobs.

The value of a VPS is cost control and predictability. You trade away automatic scale, so the setup must be easy to inspect and easy to restart at 2 a.m.

When This Pattern Fits

• You need Hermes online continuously but do not want to pay serverless burst pricing.
• The workload is steady and small enough to fit on one modest Linux box.
• You prefer direct SSH and systemd operations over managed platform abstractions.

Reference Workflow

Provision a minimal Linux host and a non-root application user.

Install Node, fetch the project, and build the production bundle.

Run Hermes behind systemd and a reverse proxy such as Caddy or Nginx.

Add backups, log rotation, health checks, and basic alerting.

Step 1: Prepare the host before copying code

Create a dedicated user, enable your firewall, and decide where app code, logs, and environment files will live. Host layout drift becomes operational pain later.

sudo adduser hermes
sudo ufw allow OpenSSH
sudo ufw allow 80
sudo ufw allow 443
sudo ufw enable

Step 2: Use systemd for boring restarts

A small VPS does not need a complicated orchestrator. A systemd unit with restart-on-failure, clear working directory, and environment file support is usually enough.

Step 3: Treat DNS and HTTPS as part of the deployment

An app that only works on localhost is not deployed. Confirm DNS records, TLS issuance, and external reachability before calling the server production-ready.

Preflight Checklist

• Run the service as a non-root user.
• Enable automatic restarts and persistent logs.
• Verify DNS, HTTPS, and external health checks from outside the box.
• Back up environment files and any local state you cannot reconstruct.

Troubleshooting

Can a $5 VPS handle Hermes reliably?

Yes for light, steady workloads. Once tasks become bursty, memory-heavy, or latency-sensitive, you will feel the limits quickly.

Should I use PM2 instead of systemd?

Systemd is enough for many deployments and reduces moving parts. PM2 can still be fine, but it is not required if systemd already gives you restart and logging behavior.

What usually breaks first on a cheap VPS?

Disk and memory pressure show up before CPU in many setups, especially when logs are unbounded or builds happen on the same machine.

Next Steps

• Docker Production Deployment — Move from a single process to a containerized setup.
• Modal Serverless Guide — Compare with an on-demand runtime.
• Security Hardening Checklist — Lock the host down before public exposure.
