System requirements

Please keep in mind that OpenStudio is a web application which needs more resources then a standard website.

Hardware

Minimum

  • 2 (v)CPU cores*
  • 2 GB of RAM
  • 1 GB of free storage

Recommended

  • 2 (v)CPU cores*
  • 4 GB of RAM
  • 10 GB of free storage
  • SSD storage

* With performance comparable to at least a second generation Intel Core i5 @ 2.0 Ghz

Hosting platform

While in theory everything used to build OpenStudio should run on Windows and MacOS as well, it’s only tested on Linux. For a production system, this is probably the best choice.

General

  • Python 2.7 (Not Python 3)
  • MySQL 5.5 or later database
  • Redis server (Tested using version shipped with Ubuntu 18.04 - 4.0.9-1)
  • Web2py (http://www.web2py.com)

Optional but recommended for a production setup

  • Nginx
  • uWSGI
  • SSL Certificate

You might want to have a look at Let’s Encrypt and support the project if you can.
