Method for automatic expansion of application examples of cloud platform based on load self-adaption

Abstract

The invention relates to the field of cloud computing, in particular to a method for automatic expansion of application examples of a cloud platform based on load self-adaption. The method for automatic expansion of the application examples of the cloud platform based on load self-adaption mainly comprises the steps that real-time load data are acquired from all the application examples in operation through an example load monitoring assembly; the received example load data are gathered and calculated through an application load analysis assembly so that the operating load of the application can be determined, comprehensive decision-making analysis is conducted according to the number of user access requests of the application, and then whether control over the expansion of the examples needs to be conducted or nor is determined; the number of the examples of the application is reduced or increased by calling a cloud platform API through an example control assembly. The method for automatic expansion of the application examples of the cloud platform based on load self-adaption has the advantages that the problem that according to an original Cloud Foundry source opening cloud platform, the expansion of the application examples are achieved manually is solved, and the problem that when the expansion of the application examples is conducted only according to the number of the user access requests, an expansion result can not be matched with the actual condition is also solved. The method is particularly suitable for the Cloud Foundry source opening cloud platform.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to an automatic scaling method for cloud platform application instances based on load self-adaptation. Background technique [0002] Cloud computing is a service delivery and usage model, which distributes computing tasks on a resource pool composed of a large number of computers, enabling various application systems to obtain computing power, storage space, and information services as needed. The basic characteristics of cloud computing are the use of resources on demand, the dynamic expansion of resources, the application of elastic computing, and the provision of services to users through the network. [0003] Elastic computing is one of the basic characteristics of cloud computing. It refers to the flexible use of computing resources by user applications according to actual business or computing needs, and truly realizes on-demand use, on-demand delivery, and on-demand payment.

Problems solved by technology

Since adding or subtracting application instances on the cloud platform is a time-consuming and resource-consuming operation, frequently adding or subtracting application instances will not only cause additional overhead for the cloud platform system, but also reduce the response processing capability of the application

Therefore, the current Cloud Foundry cloud platform application instance scaling technology solution still has great limitations
