In the next lecture, you will learn about AWS Single Sign-On (SSO).
As of July 26th, 2022, AWS IAM Identity Center has replaced AWS Single Sign-On (SSO).
From an exam perspective, they are both the same service as they perform the same functionality, and it will take AWS a long time until the exam reflects this change (usually six months).
When the exam does reflect this change, you can let me know in this form, and I will make sure to update the course right away.
Remember, if it ever happens in your exam: AWS IAM Identity Center = AWS Single Sign-On (SSO)
Happy learning!
