Verify and document that a cloud service exhibits the Rapid Elasticity characteristic per NIST SP 800-145 Section 2: capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. Document the elasticity automation mechanism (autoscaling group, horizontal pod autoscaler, serverless concurrency), the provisioning latency target, the maximum tested scale, and the cost-control guardrails. Address the elastic threat surface (quota exhaustion, denial of wallet, runaway autoscaling) in the architecture risk register.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
