NIST SP 800-145 NISTSP145-2: Resource Pooling and Multi-Tenancy Characteristic

Verify and document that a cloud service exhibits the Resource Pooling characteristic per NIST SP 800-145 Section 2: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. Capture location independence in the procurement record (consumer generally has no control or knowledge over the exact location but may be able to specify location at higher abstraction such as country, state, or datacentre). Resources include storage, processing, memory, and network bandwidth. Record the data residency capability the provider exposes and the tenancy isolation guarantee in the architecture decision record.
