Amazon VPC NAT Gateway Now Supports Tag-on-Create
Amazon VPC Network Address Translation (NAT) gateway now supports adding tags at the time of resource creation, and tag-based access control. You can define fine-grained access controls for NAT gateways using tags and AWS Identity and Access Management (IAM) policies. Tags are simple key-value pairs that you can assign to resources to easily organize, search, and identify resources, create cost allocation reports, and control access to resources.
