The remote command feature allows you to effectively perform O&M operations on cloud computers without the need to connect to the cloud computers from WUYING terminals. You can send remote commands to one or more cloud computers. You can also send remote commands to cloud computer pools. This topic describes how to use the remote command feature.
Background information
To use the remote command feature, you must activate Cloud Assistant. Cloud Assistant is a native O&M tool developed by Alibaba Cloud. You can use Cloud Assistant to remotely execute Bat, PowerShell, or Shell commands to automate O&M script execution and software installation or uninstallation on cloud computers, without having to connect to them.
By default, Cloud Assistant is installed and started on cloud computers. We recommend that you keep Cloud Assistant running to keep features at work. The service name of Cloud Assistant installed on Windows cloud computers is Aliyun Assist Service. The service name of Cloud Assistant installed on Linux cloud computers is aliyun.
