Load balance system

Abstract

The invention provides a load balance system. The system is used for performing load balance configuration on a cloud node allocated on the basis of OpenStack, and comprises a load balance module, a plurality of monitoring modules and a plurality of back end modules, wherein the load balance module is at least used for providing load balance service to the cloud node; the monitoring modules are used for performing balance calculation on the load of the cloud node and performing dynamic health examination on the back-end modules; the back-end modules are used for setting service weight corresponding to the cloud node; configuration operation for starting and / or deleting back-end service instances is dynamically executed to a network application environment of the cloud node according to configuration parameters of the updated load balance system. Through the system, the problem of load unbalance of the cloud node caused by concurrency of network access in an OpenStack-based cloud platform is solved, monitoring including health examination is dynamically performed on the back-end modules, and forward of a network request is performed according to a selective service instance with an optimal forward strategy; the system can be applied to various network topological structures, and the reliability of the cloud node is improved.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a load balancing system used by a cloud computing platform based on the OpenStack architecture. Background technique [0002] A cloud node (node) has certain virtual network resources, virtual storage resources, and virtual computing resources, and can build its own cloud node on the terminal of the cloud computing user by sending a request to the cloud computing service provider (that is, "private cloud ”) of a virtual computer. Cloud nodes are usually formed by starting huge virtual machines on physical machines built by cloud service providers. [0003] The cloud computing platform provides a large-capacity, high-configuration server cluster, which improves service capabilities and operating speed, but also faces problems such as high concurrency of network access. What load balancing realizes is to distribute the tasks of one computer to two or more computer...
