Which consumption model provides the organization with an agreed-upon number of authorized users?

Per-seat licensing, also known as per-user licensing, is a model where a specific license is purchased for each individual named user who needs access to a software product or service. This directly corresponds to an "agreed-upon number of authorized users" because each user must have their own designated license to operate the software, making it common for productivity suites and SaaS applications.

Concurrent-use licensing allows a certain number of users to access software simultaneously, but doesn't tie a license to a specific named user, only to the number of active sessions.

Volume licensing involves purchasing multiple licenses at a reduced cost for a large number of users or devices, but the core mechanism often still depends on whether it's per-user or per-device, not just the "volume" itself as the direct answer to an agreed-upon number of authorized users.

Pay As You Go is a consumption-based model where charges are incurred based on actual usage (e.g., data processed, compute time), not specifically on an "agreed-upon number of authorized users."
