Server and minimum stack

If you want 1Desk, SeaTable, n8n, and Dify AI on one small stack, the server must be sized for the AI layer first.

Minimum practical VPS​

For a pilot or small production installation, start with:

  • 4 vCPU
  • 8 GB RAM
  • 80-120 GB SSD
  • Ubuntu 22.04 or 24.04
  • Docker and Docker Compose
  • HTTPS reverse proxy
  • regular backups

This is the minimum that can work, but it is not luxurious.

Comfortable production VPS​

For a real business installation, I would rather start with:

  • 8 vCPU
  • 16 GB RAM
  • 160 GB SSD or more
  • separate backup volume or backup target
  • clear monitoring and restart policy

Rough service load​

  • 1Desk: light
  • n8n: light to medium
  • SeaTable: medium
  • Dify: the heaviest part of the stack

The bottleneck is usually memory and disk I/O, not raw CPU.

How the stack is usually published​

If you already use the 1it.pro server pattern, keep the proxy layer separate and publish apps through HTTPS on the shared proxy network.

Typical services:

  • 1desk
  • seatable
  • n8n
  • dify
  • database and cache services required by the stack

What the server must also have​

  • enough disk space for files, logs, and attachments
  • backups that can be restored
  • clean domain and subdomain mapping
  • monitoring for uptime and disk usage
  • update policy so the stack does not drift silently

What not to do​

  • do not put the AI stack on a tiny VPS and expect comfort
  • do not skip backups
  • do not expose admin ports directly to the internet
  • do not mix prod and dev data on the same instance without a reason
Practical advice

If the client expects real usage, not just a demo, Dify is the first component that deserves extra RAM.
