Embodiments of the present invention provide a method and a device for correcting a resource prediction error. The method comprises the steps of predicting the first application data of an application according to a first sequence corresponding to first historical application data so as to obtain a first prediction value; determining a first compensation value of the first prediction value according to a second sequence corresponding to second historical application data; acquiring a feature sequence according to third historical application data; determining a value range according to a preset confidence and the feature sequence; acquiring a second prediction value according to the first prediction value, the first compensation value and the value range; and allocating resources to the application at the next time moment according to the second prediction value. According to the embodiments of the present invention, the underestimated error can be corrected, and the waste of computational resources caused by the overestimated error during the resource allocation process is greatly lowered at the same time. Therefore, the operation cost of a cloud computing service providing system is lowered.
Description
technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a method and device for correcting resource prediction errors. Background technique [0002] The continuous development of cloud computing technology makes the cloud computing service provision system develop rapidly. Application developers purchase cloud computing services from the cloud computing service providing system, and the cloud computing service providing system allocates various computing resources needed to run the application to the application, and guarantees the service level agreement (Service Level Agreement) of the application during the operation of the application. referred to as SLA). Among them, the SLA of the application is agreed upon by the application developer and the cloud computing service provider system when signing the service contract, which is the threshold of some performance indicators of the application. Developers pay a l...
