Method for synchronizing heterogeneous cloud data

Abstract

The invention discloses a method for synchronizing heterogeneous cloud data, which comprises the following steps that: when a cloud platform newly builds a virtual machine, heterogeneous cloud simultaneously builds a plurality of virtual machines by using the same virtual machine mirror image or template, and the consistency of initialization data of the virtual machines is kept; and when the virtual machine is operated, an incremental snapshot of the virtual machine is created, and the incremental snapshot covers in other virtual machines through shared storage to realize data synchronization. According to the method, data synchronization of heterogeneous clouds is realized by synchronizing virtual machine incremental snapshots among the heterogeneous clouds by utilizing a shared storageand virtual machine incremental snapshot method; the problem that dynamic data such as memory data cannot be synchronized is solved, and network transmission is not needed.

Description

technical field [0001] The invention belongs to the technical field of network security, in particular to the field of mimic defense, and in particular relates to a method for synchronizing heterogeneous cloud data. Background technique [0002] Cyberspace mimicry defense theory is an active defense theory based on dynamic heterogeneous redundancy. By introducing dynamics, randomness, and diversity, mimic defense makes the operating environment heterogeneous, increases the difficulty of attacks, and effectively responds to unknown attacks. The mimetic cloud platform combines the mimetic defense theory with cloud computing to establish a heterogeneous cloud cluster, with the goal of systematically solving the security problems of the cloud platform itself. [0003] Among them, the dynamic nature of the mimicry theory requires that heterogeneous cloud platforms can achieve dynamic synchronization of data. When a user operates a virtual machine under one cloud platform, virtua...

Problems solved by technology

[0004] At present, because data transmission and synchronization cannot be realized between cloud platforms with different architectures, the data synchronization of heterogeneous clouds can only stay at the virtual machine level, and the static synchronization of virtual machine files is realized through the virtual machine network.

Although this method bypasses the problem of heterogeneity, the synchronization is only limited to the files of the virtual machine, which is not dynamic and cannot synchronize dynamic data, such as memory data.

In addition, due to problems such as network delays, this method cannot synchronize the entire virtual machine disk file

[0005] Therefore, the traditional method is not suitable for the data synchronization problem of mimic heterogeneous cloud
