Method and device for managing resources in cloud platform

Abstract

The invention discloses a method and device for managing resources in a cloud platform. The method includes: determining a resource adjustment strategy according to the first state information of the cloud platform, and the resource adjustment strategy is used to adjust the quantity of resources allocated to the application ; Determine the size of the intelligent sliding window ISW according to the second state information of the cloud platform, and the ISW is used to indicate the maximum comprehensive visit volume PV allowed by the application per unit time; wherein, the first state information and the second state The information indicates the operating status of the cloud platform when providing services for the application; according to the resource adjustment strategy, the quantity of resources allocated to the application is adjusted, and the ISW is adjusted according to the determined size of the ISW. Therefore, the method and device for resource management in the cloud platform of the embodiments of the present invention can provide stable and highly available services by adjusting the number of resources allocated to applications and the size of ISW when user visits increase suddenly.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, to a method and device for managing resources in a cloud platform. Background technique [0002] In the era of cloud computing, a large number of applications are hosted on cloud platforms. In addition to ensuring its own high availability, the cloud platform must also provide high availability guarantees for applications hosted on it. When the number of user visits to an application (English full name: Application, referred to as App) increases suddenly, for example, the promotion and promotion activities of the App are issued by social platforms, and 500,000 users are promoted at a time. In the next minute, the app suddenly increased from 2 thousand / second (2k / s) to 50 thousand / second (5w / s); or, the app was suddenly recommended by a famous person on a social platform In the case of omens, the number of user visits suddenly increases, and the number of conc...

Problems solved by technology

However, when the number of visits increases suddenly, the speed of capacity expansion often cannot keep up with the speed of concurrent visits, which will cause virtual machines or servers to crash before the capacity expansion is completed, and the virtual machines or servers with new capacity will immediately bear huge Access pressure and downtime

Therefore, when the number of user visits increases suddenly, it is difficult for both solutions to ensure stable and highly available services for users
