# Provisioning infrastructure in AMS Developer mode
<a name="developer-mode-provisioning"></a>

Users that don't have the Developer mode IAM role, `AWSManagedServicesDevelopmentRole`, in accounts where Developer mode is enabled, are required to follow the AMS Advanced change management process that leverages AMS Advanced AMIs. Users with correct role (**MALZ**: `AWSManagedServicesDevelopmentRole`, **SALZ**: `customer_developer_role`) can use the AMS Advanced change management system and AMS Advanced AMIs but are not required to. 

**Note**  
An AWS AMI, that has not been processed through AMS Advanced workload ingestion, or created in an AMS Advanced account, will not include AMS Advanced-required configurations.
