Software Asset Management licensing
Software Asset Management (SAM) licensing is based on five categories of managed IT resources: Server, End User Computing Device, SaaS Subscription User, PaaS Resources, and IaaS Storage. Each category is counted toward your subscription at a different ratio.
Each managed IT resource category is represented as a configuration item (CI) or table record in Software Asset Management. The subscription ratio differs by category, since the management effort required varies by resource type.
