Automatic retractable method and system used under cloud computing environment

Abstract

The invention discloses an automatic retractable method used under the cloud computing environment. The automatic retractable method comprises the steps that a monitoring interface of a virtual machine in an IaaS management platform is used for collecting monitoring information regularly, and the monitoring information is written to a cache; the monitoring information in the cache is analyzed; whether the analyzed monitoring information reaches the retractable threshold or not is judged; when the analyzed monitoring information reaches the retractable threshold, a retractable interface in the IaaS management platform is called according to the predefined retractable quota in the IaaS management platform, the predefined retractable quota in an application and the retractable strategy to establish or remove the virtual machine; the configuration of the application and load balance is finished through an order executing interface in the IaaS management platform. The invention further discloses an automatic retractable system used under the cloud computing environment.

Description

technical field [0001] The present invention relates to the field of cloud computing, in particular to an automatic scaling method and system in a cloud computing environment. Background technique [0002] Traditionally, vertical scaling or horizontal scaling is used to achieve load balancing. Specifically, vertical scaling improves service capabilities by increasing the performance of a single physical device, such as increasing the CPU, memory, and network card bandwidth of the physical device. Such service capability improvement often requires physical equipment to be shut down for maintenance, so business interruption will be unavoidable. Secondly, the performance improvement of physical devices has a limit bottleneck. For example, the number of CPUs and memory supported by a physical device is limited by the maturity of the technology. [0003] The traditional horizontal expansion process is generally realized by purchasing and deploying new hardware facilities. The e...

This kind of service capability improvement often requires physical equipment to be shut down for maintenance, so business interruption will be unavoidable

Secondly, the performance improvement of physical devices has a limit bottleneck. For example, the number of CPUs and memory supported by a physical device is limited by the maturity of the technology.

[0003] The traditional horizontal expansion process is generally realized by purchasing and deploying new hardware facilities. The entire decision-making and execution process is often based on weeks, and the efficiency is very low.

In addition, there may be a sudden increase in unplanned concurrent requests, leading to system paralysis. In order to prevent this situation, it is necessary to add more backup computing nodes, resulting in a large waste of hardware resources.
