Gaia Digital Agency · Compute Fleet
The host for the ERP AI orchestrator. It runs one Hermes agent — Zedano — alongside the web and database services the orchestrator needs. Currently at MVP stage.
A single Google Cloud virtual machine in Singapore, built to run the ERP AI orchestrator — the service that takes ERP work and hands it to an AI agent to carry out.
It exists as its own host rather than sharing an existing one for two reasons. The orchestrator needs memory headroom that the AI fleet host no longer has, and keeping it separate means its agent, its database, and its web tier can be restarted or rebuilt without touching anything already live.
Sizing came from measurement, not estimate. The existing agent host runs two Hermes installations at a load average near zero but with only a few gigabytes of memory to spare — so this box is specified for memory, not cores.

Serving & data
nginx 1.22.1
RunningAnswers every web request and terminates HTTPS. Serves this page, and will pass application traffic through to the orchestrator.
PostgreSQL 15.18
RunningThe database engine for the orchestrator, running on this same host. No application database has been created yet.
Certbot 2.1.0
RunningHolds the Let's Encrypt certificate for this address and renews it on a timer.
Runtimes
Python 3.11.2
RunningWhat the Hermes agent runs on. Deliberately the same version as the existing agent host, so behaviour matches.
Node.js 22.22.3
RunningFor the orchestrator's web tier, managed through nvm. Pinned to the exact version the agent fleet already runs.
Go 1.26.5
RunningInstalled from the official upstream release, not Debian's package, which is seven versions behind. Lives at /usr/local/go and is on the path for every user.
PM2 7.0.3
RunningKeeps Node applications alive and restarts them after a reboot. Nothing is registered with it yet.
Agent
Zedano Hermes Agent 0.19.0
Needs API keysZedano is the agent that orchestrates ERP work on this host — the one Hermes installation here, at /opt/hermes-zen. Installed and verified, with its bundled skills in place, but it cannot do work until model provider keys are added.
Two directories hold everything that isn't the operating system: /opt for the agent, /var/www for anything served over the web.
/opt/hermes-zen988 MB
Zedano's installation, and the only thing in /opt. This directory is the agent's whole world — its persona, configuration, conversation state, memories and skills all live here, which is why one agent equals one directory. Named to match the hermes-gen and hermes-seo pattern on the AI fleet host.
/var/www/aicenter20 KB
This page, and nothing else. A single self-contained HTML file with no build step and no dependencies, so it cannot break.
/var/www/html8 KB
Left at its default. Its one real job is answering Let's Encrypt's challenge requests when the certificate renews.
Of the 49 GB available, 8.7 GB is in use — the agent accounts for a gigabyte of that, Go for another 269 MB, and the operating system the rest. Application code for the orchestrator will sit alongside these, under /var/www.
Access is by SSH key only — no passwords, and no serial console. Two people build and run everything on this host, and both hold full administrative rights on it:
$ ssh gda-aicenter
