Policy Simulator API service.
Policy Simulator is a collection of endpoints for creating, running, and
viewing a Replay. A
Replay is a type of simulation that
lets you see how your principals' access to resources might change if you
changed your IAM policy.
During a Replay, Policy Simulator
re-evaluates, or replays, past access attempts under both the current policy
and your proposed policy, and compares those results to determine how your
principals' access might change under the proposed policy.
