HarborCart packages its stateless catalog API as an HTTP container. Demand varies sharply, and its small team wants managed scaling without Kubernetes-specific controls. Which runtime is the best initial fit?

1. A self-managed Kubernetes control plane on Compute Engine.
2. Cloud Run with tested scaling bounds and dependency capacity.
3. A continuously running analytics cluster for the HTTP frontend.
4. One fixed peak-sized VM with manual release scripts.
