問題文
An organization runs workloads with two different cloud providers and also keeps a private environment of its own. Why does this arrangement arise in practice rather than by design?
選択肢
- Private environments are required by every regulator that supervises a business of this kind, so a private part always exists in addition to whichever public providers have been chosen.
- Only one provider can host any given kind of workload.
- Providers require that every workload be duplicated with a second provider before it can be placed in production, so the presence of more than one provider is a condition of using any of them rather than a choice made by the organization.
- Individual teams adopt whichever provider suits the service they are building, and acquisitions and legacy systems add more, so the estate grows in several places at once.
