There are many ways to design IAM architecture:

  • Traditional organizations usually sync Active Directory (on-prem) with a nearly “all-in-one” cloud IAM solution like Okta or Entra ID.
  • In fully remote workspaces, some might opt to go all-in with a cloud provider like AWS, using AWS IAM for workforce IAM and AWS Cognito for CIAM.
  • In certain industries, such as higher education, institutions often rely on a mix of 10+ solutions, (many of which are industry-specific, like those provided by InCommon) all centered around a directory service like Active Directory for centralized user management.

How IAM architecture is designed depends largely on how a company stores data, strictness of compliance requirements, and complexity of its access needs.

Note: The following list of IAM solutions is not exhaustive.
