Problems solved by technology
If these commands are executed in real time in the cloud environment without control, more computing resources will be consumed, and the workload of the cloud environment will become unstable and difficult to predict and manage, thereby reducing the performance of the cloud environment
In addition, in order to execute commands in real time, it is necessary to establish a direct network connection with the remote machine. When there are a large number of commands to be executed in real time, a large number of such network connections will be established. At this time, once the network connection fails, the corresponding commands cannot be executed. , causing the task to fail
Moreover, due to the randomness of the command, the basic command line interface on the remote machine is also called uncontrollably, which increases the risk of command execution failure
On the other hand, for commands that do not need to be executed in real time, a cache mechanism is used to process these commands and temporarily store their execution results. If there is no corresponding update mechanism, the temporarily stored execution results will become inaccurate over time

Embodiment Construction
[0023] A command control method and a command controller according to embodiments of the present invention will be described below with reference to the accompanying drawings.
[0024] First, refer to figure 1 A command control method according to an embodiment of the present invention will be briefly described. The command control method may be performed by a command controller located on a management platform for constructing and updating a cloud environment and issuing one or more commands and a remote machine in the cloud environment for executing the commands issued by the management platform. between, or belong to a part of the management platform (in this case, it can be considered that the command control method is executed by the management platform).
[0025] Such as figure 1 As shown, in step S101, according to the predetermined attribute of each command in the plurality of commands, the priority of the command is determined. As described below, the predetermined...

The invention provides a command control method and a command controller which are used for controlling multiple commands to be executed on a remote machine. The command control method comprises the following steps of: determining a priority of each command in multiplex command according to a predetermined attribute of the command; determining the maximum total executing time of a command packageaccording to a current work load of the remote machine; respectively packaging the multiple commands into one or multiple command packages according to the descending order of the priorities; and sending one or multiple command packages to the remote machine. By utilizing the command control method and the command controller, the execution of the commands in a cloud environment can be optimized and the performance of the cloud environment is improved.
Description
technical field [0001] The present invention relates to a command control method and a command controller, and more particularly to a command control method and a command controller for controlling the execution of multiple commands on a remote machine in a cloud environment. Background technique [0002] At present, cloud computing has become one of the research hotspots. To effectively perform cloud computing, cloud environments need to be constructed and continuously updated. A cloud environment consists of a large number of remote machines. The remote machines mentioned here include remote physical machines and remote virtual machines, unless otherwise specified. A core method of constructing and updating the cloud environment is to remotely execute commands on the remote machine, so as to perform corresponding activities on the remote machine, or obtain dynamic information of the remote machine, wherein the dynamic information of the remote physical machine includes t...
