VPS (virtual special server) cloud host and physical server are two different hosting solutions. They have some differences in architecture, performance, flexibility, and use scenarios.

　　1. Architecture and technology:

　　VPS cloud host: VPS is a virtual server divided from physical servers through virtualization technology. Multiple VPSs can run on the same physical server, but they logically isolated.

　　Physical server: Physical server is an independent physical server that is not virtualized. It has its own hardware resources, including processors, memory, hard disks, etc.

　　2. Performance and resource isolation:

　　VPS cloud host: Although VPS has certain resources isolation, they share the resources of the same physical server. If other VPS on the physical server takes up too much resources, it may affect your VPS performance.

　　Physical server: The physical server provides more thorough resource isolation. You have independent hardware resources and are not affected by other servers.

　　3. Flexibility and scalability:

　　VPS cloud host: VPS usually has higher flexibility, you can adjust computing resources at any time as needed. It supports rapid expansion and reduction.

　　Physical server: The expansion of the physical server is relatively complicated, and it is usually necessary to buy new hardware and physical connection. Poor scalability, especially in a short time.

　　4. Management and maintenance:

　　VPS cloud hosting: The management of VPS is usually responsible for providers, including the update of hardware maintenance, network management and virtualization technology. Users mainly pay attention to their VPS.

　　Physical server: The management responsibility of physical server is more on the user, including hardware failure exclusion and operating system update.

　　5. Cost:

　　VPS cloud hosting: VPS is usually relatively economical, because multiple VPS can share the same physical server and reduce costs.

　　Physical server: Physical server usually requires greater capital investment because you need to buy independent hardware devices.

　　6. Applicable scenario:

　　VPS cloud hosting: It is suitable for small and medium -sized websites, applications and small and medium -sized enterprises. It requires more flexible resources and does not need to monopolize the entire server.

　　Physical server: Applicable to large enterprises and higher requirements for performance and security, and the resources of the entire server are required.

　　Select VPS cloud host or physical server depends on your specific needs and budgets. VPS is suitable for users who are not very high and cost -sensitive for resources, while physical servers are suitable for users with higher requirements for performance, security and resource monopoly.
