# Using service-linked roles for AWS Batch
<a name="using-service-linked-roles"></a>

AWS Batch uses AWS Identity and Access Management (IAM) [ service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role). A service-linked role is a unique type of IAM role that is linked directly to AWS Batch. Service-linked roles are predefined by AWS Batch and include all the permissions that the service requires to call other AWS services on your behalf.

AWS Batch uses two different service-linked roles:
+ [AWSServiceRoleForBatch](using-service-linked-roles-batch-general.md) - For AWS Batch operations including compute environments.
+ [AWSServiceRoleForAWSBatchWithSagemaker](using-service-linked-roles-batch-sagemaker.md) - For SageMaker AI workload management and queuing.
