Low-cost intelligent breakdown instant switching method for cloud host

Abstract

The invention discloses a low-cost intelligent breakdown instant switching method for a cloud host. The method comprises the following steps: (a) a subscriber sends a service request to a cloud management platform; (b) the cloud management platform sends the service request to the cloud host, and places the virtual disk of the cloud host in a cloud memory system; (c) when the cloud host goes wrong, the cloud management platform sends the configuration information of the cloud host to a new host machine; (d) the new host machine is connected to the cloud memory system, searches the virtual disk of the cloud host according to the configuration information of the cloud host, and is connected to the virtual disk of the cloud host; (e) a new virtual machine is created on the new host machine; (f) the cloud management platform points access routing information from the cloud host to the virtual machine, so as to fulfill breakdown switching. The method has the advantages that the resource utilization ratio is high; the failure recovery speed is high; automatic intelligent control can be realized; the reliability is high; infinite times of fault recovery can be realized without manual intervention; the disaster tolerant capacity is high.

Description

technical field [0001] The invention belongs to the field of cloud computing, and in particular relates to a low-cost cloud host intelligent fault instantaneous switching method. Background technique [0002] Cloud host is a host product in the cloud computing service system. This product effectively solves the defects of difficult management and weak business scalability in traditional physical hosts and VPS services. The price of cloud hosting service is lower than that of traditional physical hosting, and there is no need to pay a deposit. It is very flexible, and when the user's business scale expands, cloud hosting can quickly realize business expansion. Cloud computing can save users from having and maintaining complex computing infrastructure, so it is welcomed by more and more users. In order to ensure the reliability of users' business, cloud hosts need to provide failover and disaster recovery equipment. [0003] The main purpose of building a disaster recovery s...
