Problems solved by technology
[0003] In related technologies, the current memory usage of the cluster is used to judge whether the expansion requirements are met, which leads to delays in expansion, and when node expansion is performed, the way to select nodes is relatively simple, such as directly obtaining a resource from the resource pool. The capacity expansion may not solve the resource requirements of the business, but may increase the cost

Embodiment Construction
[0023] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0024] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.
[0025] At present, some companies also have relevant automatic expansion rules, but they all use the cluster CPU (Central Processing Unit, central processing unit) usage rate and cluster memory usage rate to judge whether the expansion requirements are met. Simple, for example:

The invention relates to a cluster capacity expansion method and device, and the method comprises the steps: obtaining a capacity expansion index of a cluster, enabling the capacity expansion index to comprise one or more of a resource application rate, the number of receivable service instance copies, and the number of non-operable service instance copies, and judging whether the capacity expansion index of the cluster meets a preset capacity expansion condition or not, different capacity expansion indexes correspond to different preset capacity expansion conditions, under the condition that the capacity expansion indexes meet the preset capacity expansion conditions, the duration when the capacity expansion indexes meet the preset capacity expansion conditions and the time interval between the current time and the last capacity expansion time are obtained, and when the duration is larger than the duration standard time and the time interval is larger than the cooling time, the capacity expansion indexes are obtained. And if yes, carrying out capacity expansion processing on the cluster according to the preset capacity expansion strategy, thereby accurately judging whether the cluster needs to be expanded or not, carrying out capacity expansion processing based on the related capacity expansion strategy, and ensuring that the cost is saved while the resource demand of the service is solved.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a cluster expansion method and device. Background technique [0002] At present, cluster resource expansion is a method to improve application stability and reduce enterprise costs. On-demand expansion can avoid resource waste and reduce operation and maintenance costs. [0003] In related technologies, the current memory usage of the cluster is used to judge whether the expansion requirements are met, which leads to delays in expansion, and when node expansion is performed, the way to select nodes is relatively simple, such as directly obtaining a resource from the resource pool. Expanding the capacity of each machine may not solve the resource requirements of the business, but may increase the cost. Contents of the invention [0004] In order to solve the above technical problems, the present disclosure provides a cluster expansion method and device. [0005]...
