AWS Certified Data Analytics Specialty 2021 – Hands-On - STS and Cross Account Access

The video tutorial explains AWS Security Token Service (STS), which provides temporary and limited access to AWS resources. It is primarily used for cross-account access and federation, allowing users from one AWS account to access resources in another. STS can also be used for federating non-AWS users through Active Directory, SAML, or single sign-on. The tutorial covers the Assume Role API, which enables users to impersonate IAM roles with temporary credentials. The next lecture will delve deeper into federation.
