Independent server (solo) and virtual special server (VPS) are two different types of hosting solutions. They have some significant differences in resource isolation, performance, cost, and scalability. The following is the main difference between them:

　　1. Resource isolation:

　　Independent server:

　　With an independent physical server, it does not share hardware resources with other users.

　　All computing resources (CPU, memory, disk) of the independent server are specifically assigned to a single user.

　　Has higher resource isolation and better performance stability.

　　Virtual Special Server (VPS):

　　Although virtualization technology can provide a certain degree of isolation, it is still shared hardware resources on physical servers.

　　VPS uses virtual machine (VM) technology to divide the physical server into multiple virtual instances, and each instance has some resources to a single user.

　　There is a certain neighborhood, that is, other VPS activities on physical servers may affect your performance.

　　2. Performance:

　　Independent server:

　　It usually provides higher performance because you monopolize the entire physical server.

　　It is suitable for applications that need to process large amounts of data, high flow or high performance requirements.

　　Virtual Special Server (VPS):

　　Performance may be affected by other shared VPS, especially when resource demand surges.

　　It is suitable for small and medium -sized applications and websites, and the performance requirements are relatively low.

　　3. Cost:

　　Independent server:

　　Usually more expensive than VPS because you monopolize the cost of the entire physical server.

　　It is suitable for companies with higher requirements for performance and resources and willing to pay higher prices.

　　Virtual Special Server (VPS):

　　Provide a relatively low cost because multiple users share the same physical server.

　　Suitable for small enterprises or individuals, more sensitive to cost.

　　4. Scalability:

　　Independent server:

　　More hardware resources can be added when needed, but it may need to be stopped for maintenance.

　　Virtual Special Server (VPS):

　　It has relatively good scalability, because without affecting other VPS, resource allocation can be adjusted as needed.

　　5. Management and control:

　　Independent server:

　　Provide greater freedom and control, and users can fully control software and configuration on the server.

　　Virtual Special Server (VPS):

　　Although users have certain control, they cannot modify certain configurations on the physical server by the restrictions of the host node level.

　　Independent servers are suitable for enterprises that have higher requirements for performance and resource isolation, and VPS is suitable for small and medium applications and websites with more sensitive costs and low performance requirements. Choice depends on your specific needs, budgets and expectations of performance.
