# Details
This PR gives Fleet servers the ability to connect to RDS MySQL and
Elasticache Redis via AWS [Identity and Access Management
(IAM)](https://aws.amazon.com/iam/). It is based almost entirely on the
work of @titanous, branched from his [original pull
request](https://github.com/fleetdm/fleet/pull/31075). The main
differences between his branch and this are:
1. Removal of auto-detection of AWS region (and cache name for
Elasticache) in favor of specifying these values in configuration. The
auto-detection is admittedly handy but parsing AWS host URLs is not
considered a best practice.
2. Relying on the existence of these new configs to determine whether or
not to connect via IAM. This sidesteps a thorny issue of whether to try
an IAM-based Elasticache connection when a password is not supplied,
since this is technically a valid setup.

- [X] RDS MySQL connection using username/password
- [X] RDS MySQL connection using IAM (no role)
- [X] RDS MySQL connection using IAM (assuming role)
- [X] regular (non Elasticache) Redis connection
- [X] Elasticache Redis connection using username/password
- [X] Elasticache Redis connection using NO password (without IAM)
- [X] Elasticache Redis connection using IAM (no role)
- [X] Elasticache Redis connection using IAM (assuming role)
