AWS IAM Identity Center (successor to AWS Single Sign-On) is now available in the Africa (Cape Town), Asia Pacific (Jakarta), and US West (N. California) regions. IAM Identity Center helps you securely create or connect your workforce identities and centrally manage their access to AWS accounts and cloud applications across your AWS organization. You can create user identities directly in IAM Identity Center or you can bring them from your Microsoft Active Directory or a standards-based identity provider, such as Okta Universal Directory or Azure AD. With IAM Identity Center, you get a unified administration experience to define, customize, and assign fine-grained access. Your workforce users get a portal for access to all of their assigned AWS accounts and cloud applications.
