perresource

Perresource is a concept in resource management describing approaches that apply control, accounting, or configuration at the granularity of individual resources rather than at a global level. A resource can be any unit that consumes or provides capacity, such as a compute instance, storage object, API endpoint, or data item.

In practice, per-resource management enables policies to be defined and enforced for each resource separately. This can include access control, where per-resource permissions govern who can interact with a specific resource; quotas or rate limits, where usage ceilings are assigned to each resource; and billing, where consumption is tracked at the resource level for more granular cost reporting and chargeback. Per-resource configuration allows distinct settings for different resources, such as timeout values, replication factors, or caching policies, accommodating heterogeneous requirements within a single system.

Advantages of perresource approaches include finer-grained control, improved fairness and isolation between resources, and clearer auditing and accountability. They can support multi-tenant architectures and scalable operations by preventing a single resource from affecting others. However, they also introduce higher management overhead and greater complexity, requiring robust naming, tagging, and discovery mechanisms to keep policies consistent and enforceable across all resources.

Perresource concepts appear in cloud services, API management, and configuration and policy frameworks, where isolating behavior at the resource level can improve flexibility and scalability. See also resource tagging, quotas, policy-based management, and per-resource billing.
