AWS Single Sign-On (AWS SSO) is a cloud service provided by Amazon that allows you to grant user access to AWS resources, such as Amazon EC2 instances, across multiple AWS accounts. AWS Single Sign-On centralizes the administration of users and permission sets across multiple AWS accounts using the concept of AWS organizations. This enables administrators to establish federation with an identity provider once and manage access to AWS. This integration allows organizations to use Idira Identity as an identity provider for AWS Single Sign-On, automatically provisioning users and groups, and providing simplified, secure user access to authorized AWS accounts and resources.
