Site group (or station group custody) and independent servers are two different website custody methods. They have significant differences in resource allocation, control, performance and cost. The following are the main differences between the station group and the independent server:

　　1. Resource allocation:

　　Site group: Site group is a shared hosting mode, and multiple websites share resources on the same server. This means that the server's CPU, memory, storage and bandwidth resources are shared by multiple stations. Site groups usually use virtualization technology to achieve resource isolation, but there is still the possibility of resource competition.

　　Independent server: Independent server is a hosting mode of exclusive resource. A physical server is completely used by a single customer or tenant. You have all resources on the server and you don't need to share it with other websites, so you have greater resource usability.

　　2. Control:

　　Site group: station groups are usually managed and maintained by hosting service providers, and users have limited control over the server. You may not be able to customize the server's operating system, configuration or installation of specific software.

　　Independent server: You have higher control on independent servers. You can choose and customize the hardware and software configuration of the server, including operating systems, web servers, databases and other applications.

　　3. Performance:

　　Site group: The performance of the station group is affected by shared resources. If other sites use a large amount of resources on the same server, it may affect your website performance. Performance is not as stable as independent servers.

　　Independent server: Independent servers usually provide more stable and predictable performance because you don't have to worry about the interference of resources by other users. This makes independent servers more suitable for large websites or applications that require high performance.

　　4. Security:

　　Station group: The security of the station group is affected by other sites. If a site is subject to security vulnerabilities or attacks, other sites may be threatened.

　　Independent server: Independent servers usually have higher security, because resources are not shared, you can better control the server's security configuration and access control.

　　5. Cost:

　　Site group: The cost of the station is usually low, because resource sharing can reduce costs. This makes the station group apply to projects with limited small websites or budgets.

　　Independent server: Independent server usually costs high because you need to pay all resources. This is suitable for large projects that require high performance, high availability or specific configuration.

　　The station group and independent servers have their own advantages and uses. Your choice depends on your specific needs and budgets. If you need greater resources, higher performance and more control, independent servers may be a better choice. If your demand is small and sensitive, the station group may be an affordable choice.
