Management method and device of cloud operating system, server, management system and medium

Abstract

The invention provides a management method and device of a cloud operating system, a server, a management system and a medium. The method includes: updating cloud service software of nodes in a cloud operating system according to a version change instruction, wherein the nodes comprise computing nodes; querying a service state of a virtual machine deployed in the computing node; if a running virtual machine of which the service state is a running state exists in the virtual machines deployed in the computing node, performing service switching or virtual machine migration according to the deployment type of the running virtual machine; and restarting the computing node under the condition that the service state of the running virtual machine is an idle state or a standby state.

Description

technical field [0001] The present application relates to cloud technology, for example, to a management method, device, server, management system and medium of a cloud operating system. Background technique [0002] Cloud computing uses virtualization technology to centrally deploy users' computing services (virtual machines) and cloud disks to hardware servers and disk arrays, which can greatly improve resource utilization. Cloud operating systems are used to control and manage computing node servers to ensure virtual The reliability of the computing resources and storage resources used by the computer, so as to provide computing services to users online. In actual operation, it is necessary to update the software version of the virtualized infrastructure control management (Virtualized Infrastructure Manager, VIM) and computing nodes in the cloud operating system, including the upgrade or rollback of the software version. Usually, the offline upgrade method is adopted, th...

Problems solved by technology

In actual operation, it is necessary to update the software version of the virtualized infrastructure control management (Virtualized Infrastructure Manager, VIM) and computing nodes in the cloud operating system, including the upgrade or rollback of the software version. Usually, the offline upgrade method is adopted, that is, in the Shut down all virtual machines in the cloud resource pool during the update process, and restart the virtual machines after the update is complete, resulting in interruption of business services

In the existing technology, business services can be temporarily processed through disaster recovery resource pools, but large-scale cross-resource pool operations are required, which requires sufficient network bandwidth between resource pools, and sufficient computing and storage nodes reserved to host virtual machines , the resource cost is high and the processing process is complicated; there are also some methods that use a separate network entity to assist in completing the version update, but in most application scenarios there is no similar network entity, and the processing methods of different suppliers or different types of services are different from each other. The configuration partitions are inconsistent and cannot be processed uniformly, resulting in low efficiency of version update or system management
