METHOD, APPARATUS AND SYSTEM FOR ALLOCATING RESOURCES OF APPLICATION CLUSTERS UNDER CLOUD ENVIRONMENT

摘要

Embodiments of the present application provide a method, apparatus and system for allocating resources of application clusters under a cloud environment. The method comprises: obtaining resource utilization rates of all application clusters in a specified transaction link under a cloud environment; determining resource load levels of all the application clusters according to the resource utilization rates, the resource load levels comprising a high occupancy level and a low occupancy level; applying for resources for an application cluster at the high occupancy level; releasing resources of an application cluster at the low occupancy level according to the resource load levels if the applying for resources for an application cluster at the high occupancy level fails; and allocating the released resources to the application cluster at the high occupancy level. The embodiments of the present application can level resource loads of the application clusters under the entire cloud environment, and can make full use of the existing resources to improve the resource utilization efficiency of the application clusters, so that the application clusters can support higher access traffic.
