問題文
A hospital must keep patient records on infrastructure that it owns and operates inside its own data center, but it still wants the pooling, self-service and elasticity that its developers associate with cloud. Which deployment model matches that requirement?
選択肢
- A private cloud, where the pooled infrastructure is dedicated to a single organization and can sit in that organization's own data center.
- A hybrid cloud, because any regulated workload requires two clouds, which means the hospital cannot own its records outright until it also rents capacity outside.
- A community cloud, since the records belong to a regulated industry, so the hospital shares the same pooled hardware with every other hospital that faces those rules.
- A public cloud, because a provider that serves many customers can always guarantee that one customer's records never leave the country in which that customer is located, and because a shared platform is the only way to obtain on-demand self-service.
