Abstract: Medical test peaks can triple within a few minutes, while traditional threshold-based scaling lags by 10 minutes and incurs a 45% higher cost, resulting in report delays exceeding 6 hours. This study proposes an integrated mechanism of “edge preprocessing + cloud elasticity + prediction trigger.” The edge filters invalid data in real time and reports the load, while the cloud pool scales up within 5 minutes based on “CPU > 75%” or “Flu-Prophet seasonal prediction.” Docker NS ensures CLIA-compliant hard isolation for multi-tenants. The experiment, based on 41 million real orders, maintained 99.93% availability and stabilized report issuance time at 2.4 hours under a 3.2× peak on Black Friday, with a 22% reduction in cloud bills. This study is the first to embed medical seasonal events into a cloud-edge collaborative closed loop, achieving non-collapse during peaks, cost savings, and compliance for easy replication in grassroots medical clouds.
