A hospital group ran a single DR tier because that was what the previous contract offered — and it was wrong in both directions. The EHR carried a four-hour recovery target that was clinically unacceptable. Payroll carried the same expensive commitment as the record. Clinical AI — imaging models, summarisation, retrieval — had become part of workflow with no recovery path at all. And testing disrupted clinical operations, so it was deferred and the plan remained unproven. UPC DRaaS matched recovery time to clinical impact: EHR and clinical systems on Platinum with near-zero RPO and 15-minute RTO, diagnostics on Gold, back-office on Silver — with the AI stack in scope for the first time, and drills run on on-demand compute without taking clinical systems out of service.
