Minimum server requirements for a django project

Question

I want to deploy a django project with the following stack: Django with Nginx, Gunicorn, virtualenv, supervisor and PostgreSQL.

I was thinking to use a Linode 1GB server which has:

• 1 GB RAM
• 1 CPU Core
• 24 GB SSD Storage
• 2 TB Transfer
• 40 Gbit Network In
• 125 Mbit Network Out

At the beginning I expect to have very low traffic. Is a Linode 1GB enough or should I choose a better one with more RAM/cores? I would like to choose the minimum one that fits my needs now and upgrade as the traffic grows.

Bonus general question: How can I calculate the server requirements for a specific stack and traffic?

Solution

Is a Linode 1GB enough

Well, it'll all run on that. You don't say what sort of load you want to support though.

So - here's what you want to do.

1. Add some basic monitoring into the mix - mem/cpu/disk/network traces + record them.
2. Script your server so you can go from an empty vm to working system automatically. There's all sorts of stuff out there - puppet/chef/vagrant. You're already using python, so ansible might suit you.
3. Now test it. Fire up a local VM (or hire a Linode one by the hour) and stress-test it.
4. Rent a bigger one + test that too.

Now you know what size VM you need and when you'll need to switch.

An open source load testing tool. locust.io. I think, this will be useful.
