## AI overview

The article explains how MongoDB Atlas uses Cedar-based resource policies to decouple authorization logic from application code. It discusses role- and attribute-based access control, policy verification, centralized governance, and enforcement across multi-tenant database deployments and cloud providers.

## Source excerpt

As organizations scale applications, managing authorization becomes increasingly complex. What starts as role-based permissions quickly evolves into intricate rules spanning multiple services, regions, and compliance requirements. Traditional approaches of embedding authorization logic in application code lead to fragmented policies scattered across codebases, making them difficult to maintain, audit, and scale. These challenges have become more [...]
