This repository contains educational lab materials for a university course on scalable systems design.

The code is intentionally simplified for learning purposes. Some labs use configurations that would not be appropriate for production environments.

If you find a real security vulnerability in any script, configuration, or application code in this repository, please do not open a public GitHub Issue.

Instead, report it privately via email: alejandrogarcia@iteso.mx

Include:

• The affected file or module
• A description of the vulnerability
• Steps to reproduce (if applicable)

Reports will be reviewed and addressed as course materials are updated. This is an educational repository, so the priority will be to correct the material and add a learning note where relevant.
