You can now use AWS Config to assess license compliance on Dedicated Hosts by turning on recording for instances and hosts. AWS Config records when instances are launched, stopped, or terminated on a Dedicated Host, and pairs this information with host and instance level information relevant to software licensing, such as Host ID, Amazon Machine Image (AMI) IDs, number of sockets and physical cores. This enables you to use AWS Config as a data source for license reporting.
