Method, node manager and system for load balancing in cloud computing system

Abstract

The invention discloses a method for load balancing in a cloud computing system. The method comprises the following steps of: receiving a registration request of each access node and each service node, wherein the registration request carries respective node identifier and address information; correspondingly storing the node identifier and the address information of each access node, and correspondingly storing the node identifier and the address information of each service node; monitoring the load accessing capacity of each access node after registration and the load handling capacity of each service node after registration; receiving a load access request message transmitted by a user side; transmitting the load access request message to any access node of which the load accessing capacity is not fully used, and enabling the user side to have access to the cloud computing system; and transmitting the load handling capacity of each service node to each access node, and enabling the access node to distribute the accessed load to any service node of which the load handling capacity is not fully used. The method provided by the embodiment of the invention realizes massive access in the cloud computing system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a load balancing method, a node manager and a system in a cloud computing system. Background technique [0002] In the cloud computing environment, there will be a large number of Simple Object Access Protocol (SOAP, Simple Object Access Protocol) and Architecture State Transfer Protocol (RESTful, REpresentation State Transfer) based on Hypertext Transport Protocol (HTTP, hypertext transport protocol), etc. As well as access to other non-HTTP protocols, how to quickly and efficiently complete mass access and codec of multiple protocols is a problem that must be considered by the cloud computing platform. [0003] In cloud computing systems, the access components are generally the core components of the business system, responsible for the access and distribution of external services, and have extremely high requirements for performance and reliability. The traditional solu...

Problems solved by technology

[0004] During the research and practice of the prior art, the inventors of the present invention found that under the cloud computing environment, there are various types of services, and the amount of requests varies greatly, and the amount of requests for the same service in different periods also varies greatly. As an access node, the hardware load balancer is difficult to expand horizontally. Therefore, although it can handle many concurrent requests, its capacity is limited, and it cannot realize massive access requests in the cloud computing environment.
