Web system resource management method and system in cloud computing environment based on SDN

Abstract

The invention discloses a web system resource management method and system in a cloud computing environment based on an SDN. The method comprises the following steps: S1, constructing a web application system in the cloud computing environment based on the SDN; S2, acquiring the number of instantaneous session connections and the instantaneous link traffic of each server at every preset time; S3, if the numbers of instantaneous session connections obtained by any server for two consecutive times are greater than the maximum threshold of the number of instantaneous session connections, performing a resource leveling operation, and otherwise, executing step S4; S4, acquiring the average number of session connections and the average link traffic; S5, separately comparing the average number of session connections of each server with the maximum threshold of the average number of session connections and the aggregated threshold of the average number of session connections; and S6, performing the resource leveling operation or resource aggregation operation according to comparison results. The web system resource management method and system disclosed by the invention have the beneficial effects of saving server resources and effectively improving the utilization efficiency of existing resources.

Description

technical field [0001] The present invention relates to the technical field of SDN, in particular to a method and system for managing web system resources in an SDN-based cloud computing environment. Background technique [0002] Cloud computing is the product of the development and integration of traditional computer and network technologies such as distributed computing, parallel computing, utility computing, network storage, virtualization, load balancing, and hot backup redundancy. It is a new computing model that pays by usage. This mode provides available and convenient network access and uses on-demand computing resources, including networks, servers, storage, application software, services, etc. Due to its high reliability, easy scalability, low maintenance and use costs, virtualization and other advantages, cloud computing technology has developed very rapidly in recent years, and is widely regarded as another technological revolution in the information field.

Problems solved by technology

Due to the problem of simultaneous concurrent access by multiple users in the web application system, in this case it is necessary to dynamically adjust the server cluster scale and network link traffic. Under the current traditional network conditions of cloud computing, the data forwarding plane and the control plane are closely integrated, which cannot be realized. Automatic session and traffic load balancing operations, such as monitoring too many concurrent sessions of multiple users, link traffic congestion, low link utilization, etc., and cannot automatically adjust resources according to po
