What is VPS n8n and How to Choose the Right VPS for Running n8n

When deploying workflow automation solutions, n8n is a powerful tool increasingly chosen by businesses and individuals. To operate n8n stably and continuously, using a VPS (Virtual Private Server) is the optimal solution. This article will help you understand VPS n8n and how to choose the right VPS to run n8n effectively.

What is n8n?

n8n (pronounced as "engine") is an open-source workflow automation platform that allows you to connect and integrate various applications and services without requiring deep programming knowledge. Similar to Zapier or Make (formerly Integromat), n8n helps automate repetitive tasks between different applications.

Some notable advantages of n8n compared to other automation platforms:

  • Completely open-source and free
  • Can be self-hosted on your own server
  • Ensures high data privacy
  • Supports many integrations with popular services
  • Intuitive and user-friendly interface

Why Do You Need a VPS to Run n8n?

Although n8n can run on a personal computer, using a VPS (Virtual Private Server) is necessary to ensure automated workflows operate continuously 24/7. A VPS provides a stable environment, high uptime capability, and dedicated resources for n8n.

Benefits of running n8n on a VPS:

  • Continuous 24/7 operation without interruptions
  • Stable performance, independent of personal computers
  • Scalability as the number of workflows increases
  • Static IP address, convenient for connecting to APIs
  • Better data security

VPS Configuration Requirements for Running n8n Effectively

n8n doesn't require extremely high configurations, but to ensure good performance, especially when running multiple complex workflows, you should consider the following resource requirements:

1. CPU

n8n can run with 1 CPU core, but to ensure good performance when running multiple workflows simultaneously, it's recommended to use at least 2 CPU cores.

2. RAM

Minimum 2GB RAM, but 4GB RAM is recommended to handle complex workflows or when multiple workflows run simultaneously.

3. Storage

About 20GB SSD is sufficient for most cases. However, if you store a lot of data or use a large database, consider increasing the storage capacity.

4. Operating System

n8n works well on Linux operating systems such as Ubuntu, Debian, CentOS. Ubuntu 20.04 LTS or newer is a popular and stable choice.

5. Bandwidth

Choose a VPS with unlimited or generous bandwidth to ensure n8n operates without interruptions when processing tasks involving large data transfers.
