An IAM user in the same AWS account as the role

A web service offered by AWS such as Amazon Elastic Compute Cloud (Amazon EC2)

Applications running on that instance can retrieve temporary security credentials and perform actions that the role allows

You can use AWS Security Token Service (AWS STS) to create and provide trusted users with temporary security credentials that can control access to your AWS resources. For more information about AWS STS, see Temporary security credentials in IAM. AWS STS is a global service that has a default endpoint at https://sts.amazonaws.com
