Amazon EC2 Capacity Manager Updates

Amazon EC2 Capacity Manager now offers real-time supportability checks and capacity fulfillment metrics. These features help customers find capacity by scoring how well each instance type and Availability Zone can support a request, without launching or reserving instances. Capacity fulfillment metrics show how much capacity was delivered against the amount requested.

Global enterprises can now use the supportability checks in Capacity Manager to understand which Availability Zones and instance types give them the best chance of getting the capacity they need. The check returns a High, Medium, or Low score for each option, plus an overall score. Additionally, with fulfillment metrics, customers can measure fulfillment rates across their AWS organization, accounts, Regions, and tagged workloads, with a breakdown by instance type and Availability Zone.
