It has low delay, high bandwidth and good stability, and is suitable for application scenarios that require high quality network connections.

Bandwidth and flow limitation:

According to your site group needs and estimated website visits, choose the appropriate bandwidth and traffic limit. Ensure that the bandwidth of the server can meet the needs of all websites in the station group, and avoid website access speed restrictions due to bandwidth restrictions.

Hardware and configuration:

Consider the hardware performance and configuration of the server, including processor, memory, storage, etc. Make sure the server's hardware can support the operation and access requirements of all websites in your site group.

Security and technical support:

Make sure that the server provider provides good security measures, such as firewalls, DDoS protection, etc., and provides 24/7 technical support to deal with possible problems and failures.
