Data synchronization method and device between cloud server clusters

Abstract

The invention provides a data synchronization method and device between cloud server clusters. The method comprises the following steps: if a business service in a cluster updates Redis cache data, judging whether an updated data object is monitored target business data or not; if yes, adaptively modifying the first hash tree according to the updated content, wherein the first hash tree is used for recording the latest data state of the monitored target service data in the cluster; if the target service data is concerned by the first cloud server cluster, notifying the first cloud server cluster that the target service data is changed, enabling the first cloud server cluster to determines update content by comparing a Hash tree maintained by the first cloud server cluster with a first Hash tree, and synchronizing the update content to a Redis cache of the first cloud server cluster. According to the method and the device, the data sharing efficiency and security among the cloud server clusters are improved.

Description

technical field [0001] The present application relates to the technical field of cloud computing, and in particular, to a data synchronization method and device among cloud server clusters. Background technique [0002] With the development of cloud computing technology, relying on the powerful computing power of the cloud, more and more cloud applications are deployed on the cloud. In the scenario of large-scale deployment of cloud applications, the number of cloud servers is very large, often requiring Deployment in the computer room, the cloud server deployment in different computer rooms has different business services, when the business service runs in a distributed manner, its architecture design often relies on the Redis (Remote Dictionary Server, that is, remote dictionary service) distributed cache method To achieve stable system operation. Some of the data in the Redis cache is configuration global data. The maintenance and configuration of this type of data is pe...

Problems solved by technology

[0003] In related technologies, the implementation of the cross-computer room use of Redis cache data is generally to store data that needs to be used across computer rooms in a unified Redis storage system on the public network for access and acquisition by necessary computer rooms. Public network exposure will bring great challenges to data access security control (for example, the occurrence of Redis6379 port vulnerabilities, etc.); in addition, in this method, multiple computer rooms access cached data across networks, which will have a high impact on the bandwidth and quality of the public network. requirements
