Amazon ElastiCache now supports Tag-Based Access Control

Amazon ElastiCache now supports tag-based access control and adding tags to additional cluster resources. By using tags for access control, your AWS Identity and Access Management (IAM) users, groups, and roles get access only to the Amazon ElastiCache resources with matching tags. This provides you the capability to scale by reducing the number of distinct permissions you need to create and manage in your AWS account. You can define AWS IAM policies that grant or deny access to a resource based on its tags. Furthermore, you can use specific condition context keys to customize your AWS IAM policies to limit specific behaviors on Amazon ElastiCache resources. For a complete list of condition context keys for Amazon ElastiCache, visit the Amazon ElastiCache documentation.
