Abstract

An embodiment of the invention provides a processing method and a device for elastic load balancing. The method includes obtaining numbers of session information in each virtual load balancer (VLB) under an elastic load balancer (ELB), selecting one VLB from the VLBs under the ELB as a VLB to be migrated when the numbers of session information in each VLB are smaller than a threshold, wherein the session information number in the VLB to be migrated is smaller than that in the other VLBs; sending migration requirement information carried with the identity of the VLB to be migrated to a domain name system (DNS) which is enabled to select one VLB from the other VLBs as a target VLB according to the migration requirement information; and receiving the identity of the target VLB sent by the DNS, and migration the session information in the VLB to be migrated to the target VLB corresponding to the target VLB identity. According to the processing method and the device, dynamic migration of the session information is achieved while business is not interrupted, and resource consumption is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a processing method and device for elastic load balancing. Background technique [0002] After the web server cluster, because after load balancing, the same IP accessing the same page will be assigned to different servers. Therefore, in order to avoid a logged-in user, sometimes it is in the login state, and sometimes it is not in the login state. , It is necessary to realize the synchronization problem of the session. [0003] Currently, session synchronization is also required in an elastic load balancer (ElasticLoadBalancer, hereinafter referred to as: ELB). However, when it is found that there is only a small amount of session information in one of the multiple virtual load balancers (VirtualLoadBalancer, VLB) under an ELB, the VLB cannot be deleted, and the session information on the VLB cannot be deleted. It can only be deleted when ...
