+Red Hat OpenShift Service on AWS (ROSA) is a fully-managed turnkey application platform that allows you to focus on what matters most, delivering value to your customers by building and deploying applications. Red Hat and AWS SRE experts manage the underlying platform so you do not have to worry about infrastructure management. ROSA provides seamless integration with a wide range of AWS compute, database, analytics, machine learning, networking, mobile, and other services to further accelerate the building and delivering of differentiating experiences to your customers.
+
+ROSA makes use of AWS Security Token Service (STS) to obtain credentials to manage infrastructure in your AWS account. AWS STS is a global web service that creates temporary credentials for IAM users or federated users. ROSA uses this to assign short-term, limited-privilege, security credentials. These credentials are associated with IAM roles that are specific to each component that makes AWS API calls. This method aligns with the principals of least privilege and secure practices in cloud service resource management. The ROSA command line interface (CLI) tool manages the STS credentials that are assigned for unique tasks and takes action on AWS resources as part of OpenShift functionality.
+//For a detailed explanation, see "ROSA with STS Explained" (add xref when page is migrated).
+
+A list of the account-wide and per-cluster roles is provided in the xref:../../rosa_architecture/rosa-sts-about-iam-resources.adoc#rosa-sts-account-wide-roles-and-policies-creation-methods_rosa-sts-about-iam-resources[ROSA documentation].
