(2) physical cloud is suitable for scenarios with high performance requirements and hardware customization requirements. Generally speaking, most physical cloud servers are used for database, distributed storage and other services. Databases require very high performance, and distributed storage services require large-capacity hard drives.

(3) hosted cloud: it is suitable for enterprises with their own assets. The existing servers can easily communicate with the public cloud through the managed cloud service.
