Category: AWS IAM Identity Center

AWS IAM Identity Center (successor to AWS Single Sign-On) provides administrators with a simple way to manage identity and access (IAM) across numerous AWS accounts. IAM Identity Center is available in the AWS GovCloud (US) Regions, enabling customers to simply manage access to numerous AWS accounts in their AWS GovCloud (US) organizations. In this blog post, learn four different architecture patterns for providing an organization’s AWS users with access to both standard and AWS GovCloud (US) accounts using IAM Identity Center that can help minimize administrative overhead and simplify the user experience.

AWS IAM Identity Center helps administrators centrally manage access to multiple AWS accounts that are members of an AWS Organization. End users can authenticate and then access all their AWS accounts from a single interface. Using IAM Identity Center as a SAML identity provider for your AWS accounts also has security benefits: user credentials provided via federation are temporary. IAM Identity Center does not automatically detect AWS GovCloud (US) accounts associated with standard AWS accounts in your AWS Organization. IAM Identity Center is also not currently available in AWS GovCloud (US). As a result, IAM Identity Center cannot be used to automatically provision access for your users into an AWS GovCloud (US) account. However, this functionality can be extended to enable federation into AWS GovCloud (US) with a “custom SAML 2.0 application” in IAM Identity Center.
