A Method for Adaptive Cloud Data Migration

Abstract

The invention discloses a method for self-adaptive cloud data migration. The steps include: a sending module of a physical host sends a request for migrating data to a cloud host; and after receiving the request, a receiving and analyzing module of the cloud host establishes a transfer of migration data with the sending module channel; the sending module of the physical host detects the current business traffic transmission value between the physical host and the cloud host, and detects the maximum network traffic transmission value of the network transmission interface of the physical host; the sending module detects the current business traffic transmission value and The maximum network traffic transmission value is analyzed and processed to obtain the transmission bandwidth required for migrating data, and according to the obtained transmission bandwidth required for migrating data, the physical host transmits the migration data to the cloud host. The invention transmits the migrating data adaptively and does not need to shut down the physical host during the transmission process, and ensures that the current service flow of the physical host can be transmitted preferentially.

Description

technical field [0001] The invention relates to the technical field of computer data migration, in particular to a method for adaptive cloud data migration. Background technique [0002] With the development of Internet cloud computing, more and more physical hosts need to migrate cloud data, cloud migration on physical hosts (the environment of physical devices is migrated to cloud devices), and cloud (virt-p2v) and virtual On-board cloud (virt-v2v is an open source) technology. In the existing technology, the data needs to be copied and migrated after shutting down during the process of going to the cloud. [0003] Traditional data migration steps: 1. Use the virt-p2v / virt-v2v tool to convert the disk of the physical device to the cloud (virtualized format, usually using RAW disk format); 2. Mirror copy and transfer through the network (from the physical device to the cloud). [0004] Problems in traditional data migration: 1. In order to ensure data consistency, the sou...

Problems solved by technology

[0004] Problems in traditional data migration: 1. In order to ensure data consistency, the source device (physical device) is usually shut down, which basically leads to business loss; External traffic is basically used for transmission)
