AWS Compute Optimizer now supports the ability to filter your rightsizing recommendations by tags in the AWS GovCloud (US) Regions. This includes tag keys, tag key and value pairs, or combinations of both. Tag filtering will be available on these rightsizing recommendations pages: Amazon Elastic Compute Cloud (EC2) instance types, Amazon Elastic Block Store (EBS) volumes, AWS Lambda functions, and Amazon Elastic Container Service (ECS) services on AWS Fargate.
