Supported Server Types

  • ECS
  • BMS
  • Third-party cloud server
  • Offline server

    HSS does not allow multiple offline servers to use the same EIP. A server protected by HSS must use a unique EIP. If there are servers sharing the same EIP, contact technical support.

Supported OSs

HSS agents can run on Linux OSs, such as CentOS and EulerOS; and Windows OSs, such as Windows Server 2012 and 2016.

The agent is probably incompatible with the Linux or Windows OS versions that have reached end of life. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
