Method and system for expanding and contracting resource quantity of resource pool of paas platform

Abstract

The invention discloses a method and a system for expanding and shrinking the resource quantity of a resource pool of a PAAS platform. Wherein, the method for expanding the resource quantity of the resource pool includes: counting the number of virtual machines applied for in the first cycle, and calculating the first application speed; comparing the first application speed with a predefined application speed threshold; if the first application speed is greater than Application speed threshold, count the number of application virtual machines in the second cycle to calculate the second application speed; and compare the first application speed with the second application speed, determine the larger one, and return the larger application speed The corresponding period and number of virtual machine applications are used as the extension period and number of virtual machine extensions used for resource expansion. The present invention calculates and compares the application / return speed of the virtual machine, and can automatically expand or shrink the resource quantity of the resource pool according to the actual use of the virtual machine, thereby realizing more effective utilization of the resource pool.

Description

technical field [0001] The present invention relates to the field of cloud computing, and more specifically, to a method and a system for expanding and shrinking the resource quantity of a resource pool of a PAAS platform. Background technique [0002] PAAS (Platform-as-a-Service, Platform as a Service) platform is a business model that provides a server platform as a service. In the era of cloud computing, the corresponding server platform or development environment is provided as a service, which becomes PAAS. The platform service application mentioned in the present invention is an application that provides basic service capabilities based on the PaaS platform. [0003] The PAAS platform refers to the application infrastructure service in the cloud environment, and it can also be said to be middleware as a service. The PAAS platform is located in the middle layer of the cloud architecture, its upper layer is SAAS (Software as a Service), and its lower layer is IAAS (Inf...

AI Technical Summary

Problems solved by technology

[0005] However, the expansion and scaling of the resource pool of the current mainstream PAAS platform is mainly described by a fixed configuration, that is, the number of automatic expansion and automatic contraction is fixed, so that only a certain number of virtual machines can be created or a certain number of virtual machines can be deleted
