The update enabled users to activate up to five custom tag keys (e.g., environment, team) to organize capacity usage metrics for On-Demand and Spot Instances, improving granularity in monitoring. The new Account Name built-in dimension facilitates clearer identification of multiple accounts within organizational views.
This enhancement supports flexible analysis of capacity data by combining tag-based grouping with existing dimensions like Region and Availability Zone. It also includes default tags for services such as EC2 Auto Scaling and EKS clusters, with availability across all AWS Regions where Capacity Manager operates as of April 2026.
