Term	Kind	Topic	What it is
Billable-Event Metering Contract-Aligned Metering, Obligation-Point Metering	practice	Licence & Vendor Costs	Recording the event a contract actually charges for at the point in the system where that obligation is created, rather than inferring it from delivery telemetry that caching and retries make unreliable.
Licence Costs	concept	Licence & Vendor Costs	Software licensing whose pricing model frequently constrains architecture more than its technical characteristics do.
Licence Metric Risk	concept	Licence & Vendor Costs	The exposure created when a software licence is priced on a unit that cloud architecture changes unpredictably, such as cores, sockets or instances.
Sub-Capacity Licensing Virtualisation Capacity Licensing, Sub-Capacity Entitlement	practice	Licence & Vendor Costs	The vendor programme that allows a per-core licence to be counted against the cores a workload is actually allowed to use, which is conditional on approved metering and reverts to the whole host when the meter…
