🔶 Adding Determinism and Safety to Uber IAM Policy Changes

Uber's production environment relies on a complex network of microservices and assets governed by IAM policies. Managing these policies effectively without disrupting production is challenging, as highlighted by an incident where an accidental IAM policy change caused Uber Eats outages. To address this, Uber introduced a Policy Simulator tool that allows policy authors to preview the impact of proposed changes in real time.
