With the rapid development of information technology, especially the development of internet technology, the demand of users for computing and storing data is increased dramatically, and the traditional mode of satisfying the demand of users by purchasing a large number of high-performance servers will greatly increase the waste of resources. Cloud Computing (Cloud Computing) technology is applied, and is referred to as providing available, convenient, on-demand network access into a shared pool of configurable Computing resources including networks, servers, storage, application software, services, and the like, such that the resources can be provided quickly with little administrative effort or interaction with the service provider. As an emerging research and application field in the internet technology, the internet technology is receiving more and more attention, and has rapidly spread and become popular in recent years, because it adapts to a new computing model in which a network service is shifted from a service configuration of "high concentration, high cost, low pass use" to "high distribution, low cost, high pass use", as an emerging research and application field in the information technology, is receiving more and more attention from related enterprises and research institutions, and is regarded as a necessary trend of a future computing model.

It is due to these advantages of cloud computing that there are a number of problems in implementation: the number of node computing devices in a cloud computing environment is becoming larger and larger, and the energy consumed is increasing. For example, cloud computing devices from google, usa consume 1 billion KWh of electricity per year, which is quite large, approximately equal to the total energy consumption of a small city. Particularly, different periods of different requirements for the use of the node computing equipment are different, the use requirements in daytime and working days are large, and more node computing equipment is called; on the contrary, at night and on weekends, the use demand is small, the number of the called node computing devices is small, at the moment, if the node computing devices are in operation or are in operation delay waiting standby, energy is greatly wasted, higher energy consumption becomes a bottleneck restricting the development of cloud computing, and today advocating energy conservation and emission reduction, the state needs to be improved urgently.

a fourth component, configured to migrate, if there are enough node computing devices in the low power consumption state, the virtual machine in the previous step to the node computing device in the low power consumption state according to the performance and capacity of the central processing unit, the static memory, and the dynamic memory of the node computing device in the low power consumption state; if the data is insufficient, according to the performances and capacities of a central processing unit, a static memory and a dynamic memory of the node computing equipment in the low power consumption state, the signing performance and capacity are divided by the unit processing capacity, and data of an integer number of unit processing capacity are transmitted to the node computing equipment in the low power consumption state by adopting a rounding and tailing removing method; wherein the low power states include, but are not limited to, sleep, standby, running into delayed waiting.
5. The enhanced cloud computing environment power saving device of claim 1 or 4, wherein the client comprises any one of: a user, a desktop or laptop PC, a terminal with PC functionality or a user equipment UE in communication technology.
6. The enhanced cloud computing environment energy saving device of claim 1 or 4, wherein the cloud computing environment platform recognizes the type of information in the request, removes the header information of the request, and retains, evaluates and acquires the information to be processed, i.e. the workload of the to-be-computed processing, included in the request.
7. The enhanced cloud computing environment power saving apparatus of claim 1 or 4, wherein the priority of the existing node computing device is determined based on the performance and capacity of the central processor, the static memory, and the dynamic memory of the node computing device, and these parameters are periodically updated to the cloud computing environment platform.
8. The enhanced cloud computing environment energy saving apparatus of claim 1 or 4, wherein the information processing margin in the existing node computing device is a preset threshold of the existing node computing device minus a workload at a current time point, the preset threshold being a ratio multiplied by a total performance and capacity of the node computing device.
