AI Technical Summary
Problems solved by technology
However, due to the dynamic variability of the system load, it is often difficult for the fixed interval control strategy to respond quickly to the load surge in a short period of time.
(2) Lack of mechanism for quantitative trend prediction
The existing technology does not fully analyze, model and predict the historical load data of the system, but mostly uses historical average or recent data as the basis for control decisions.
(3) The difference between different hosts is not considered
The existing technology treats all hosts in the IaaS cloud equally, adopts the same control strategy and control time interval, and does not consider the differences in load and execution efficiency of different hosts

Embodiment Construction
[0087] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0088] Such as figure 1 Shown, a kind of IaaS cloud system operating rate dynamic control method, comprises the following steps:
[0089] Step 1. Collect the inventory task time information of the IaaS cloud system host:
[0090] In this embodiment, the execution time series ct of the last k completed tasks on the host of the IaaS cloud system are collected. l , ct 2 ,...ct k and the used execution time series of tasks still executing on the IaaS cloud system host 1 , et 2 ...et m , where m is the number of tasks still being executed, both k and m are positive integers, 5≤k≤10, the time series ct 1 , ct 2 ,...ct k It is the execution time sequence on the IaaS cloud system host in the order of completion.
[0091] Step 2. Predict the execution time to complete the task:
[0092] Set the completed tasks in the execution time series on the host of the...

The invention discloses a device, a system and a method for dynamically controlling the running speed of an IaaS (infrastructure as a service) cloud system, belongs to the field of cloud computing, and aims to change the running speed of a cloud host, instantly respond to the change of a load and accordingly optimize system performances and energy consumption, so that the system takes execution efficiency under a high-load condition and energy conservation under a low-load condition into account. Dynamic fluctuation of the load of the cloud system is taken fully into account, the requirement of the cloud system for future running speed is predicted by tracking the trend of the cloud system, and acceleration or deceleration is controlled in advance. As the influence of abnormal points in historical load data is removed, trend prediction accuracy is ensured. Future expected load gaps are estimated, variable control interval time is set, and the extremes of 'too dense control' and 'too sparse control' are avoided.
Description
technical field [0001] The invention belongs to the field of cloud computing, and in particular relates to a device, system and method for dynamically controlling the operation rate of an IaaS cloud system. Background technique [0002] Cloud computing is an Internet-based computing method in which shared hardware and software resources and information can be provided to computers and other devices on demand. Compared with traditional software and computing forms, cloud computing has significant advantages such as loose coupling, on-demand, cost control, resource virtualization, heterogeneous collaboration, etc., making it more suitable for today's e-commerce, flexible manufacturing, mobile Internet and other applications . Cloud computing includes two meanings: one is the underlying cloud computing platform infrastructure, which is the basis for building upper-layer applications; the other is the cloud computing applications built on this basic platform. Cloud computing c...
