Amazon Neptune adds tag-based IAM access control (TBAC)

Tue, 28 Jul 2026 12:49:37 +0000

Platform/SRE — Plan: New GA Neptune capability that replaces static ARN enumeration in IAM policies with attribute-based cluster access using resource and principal tags; plan to adopt TBAC if you operate multiple Neptune clusters in shared VPC environments to enforce team and environment isolation.
CI/CD — Skip
Leader — Learn: Neptune now supports attribute-based access governance across clusters via IAM tags, useful context for organizations running Neptune at scale, but no strategic, licensing, or cost decision is triggered.
