Cloud loading method of physical server, readable storage medium and cloud migration system

Abstract

The invention relates to the field of cloud computing, in particular to a cloud loading method of a physical server, which comprises the following steps: a cloud migration step of migrating data in a disk space of a source end to a target end; and a service switching step of, after the cloud migration step is completed, carrying out service switching between a source end and a target end. The method further comprises an incremental migration step executed together with the cloud migration step, and incremental data generated by a source end is migrated to a target end in multiple times from the time point when the cloud migration step is started. According to the automatic cloud loading method of the physical server, the user can perform migration operation while not closing the service, so that the service of the user is ensured to be affected to the minimum extent. When a system service is online, the whole disk is copied through full-volume migration at a fixed point, full-volume data is transmitted through a network, then the data generated in the full-volume migration process is copied into the target VM again in an increment mode, and the consistency of the data is ensured.

Description

technical field [0001] The present invention relates to the field of cloud computing, in particular to a cloud migration method for a physical server, a cloud migration system, and a computer-readable storage medium. When the computer-readable storage medium is executed by a processor, the cloud migration method for the physical server can be realized. Background technique [0002] The emergence of cloud computing has brought about a new IT infrastructure construction, use and delivery model. Cloud server providers obtain virtual machines through server virtualization technology and provide them to users as business servers, which can achieve more fine-grained resource utilization. Compared with traditional physical machines, the deployment of virtual machines is more convenient and fast, and can be migrated between different physical machines, which improves the flexibility of resource scheduling. [0003] As cloud computing enters a mature stage and enterprise data center...

Problems solved by technology

Every business system needs to stop external services from the beginning of the cloud operation, especially when exporting data, in order to ensure the data consistency after the cloud, it needs to stop the service until the cloud is completed before continuing to provide services, from operating system deployment, There are many links in data export, data import, business deployment, and result verification, and the final result is difficult to predict. It is possible that the migration may fail due to compatibility issues after the migration is completed.
