Lesson 1Identity and access control: IAM, Azure RBAC/AAD, GCP IAM — roles, service principals, cross-account access basicsCompare how identity and access work in AWS, Azure, and GCP. Get to know IAM roles, Azure AD and RBAC, service principals, and basic cross-account access to build secure patterns for multi-cloud use that protect your resources effectively.
