Before this update, restricting access to AWS HealthOmics workflows required creating multiple IAM roles for tenants or runs, which increased complexity. Support for IAM session policies allows applying inline, temporary policies that further restrict permissions at runtime without modifying the underlying roles.
This capability simplifies access management and supports scenarios such as limiting S3 bucket access per tenant or granting temporary, isolated access for individual analysis runs. AWS made this feature available in multiple global regions and positioned HealthOmics as a HIPAA-eligible service for sensitive healthcare research environments.
