specific Embodiment approach

[0031] 1. Overall architecture of highly available cloud storage method:

[0032] Such as figure 1 As shown, the overall architecture of this solution consists of the following parts: the cloud storage operation module on the client side, the storage data processing module on the cloud storage server side (including data storage, data recovery, and data modification), and the data encoding and decoding module. The user submits the file operations he needs to the cloud storage service, and the cloud storage service analyzes the user's request and makes a specific response. The storage data processing module on the server side is mainly to make corresponding deployment for distributed file storage and modification, which mainly involves data segmentation, data transmission, data retrieval, dynamic data support and data merging. The data encoding and data decoding modules are the main redundant storage schemes of this scheme. Encoding data can generate enough redundant items to ...

Abstract

The invention discloses a redundancy storage method for encoding files through a Vandermonde matrix. At the time of storage, multiple data blocks obtained through segmentation after encoding are dispersed to multiple storage service nodes, a chord ring is used for quickly finding and locating the data blocks of the files, and the data blocks are decoded and combined to be read finally. By means of the scheme, autonomous management of the storage nodes and cooperation can be realized to a certain degree, as a result, high availability, high flexibility, a high storage utilization rate and other properties can be provided for a cloud storage system, the utilization rate of cloud storage resources can be increased, rental cost is lowered for a user, and the expansibility of an application is improved. The scheme can be applied to the field of cloud computing and cloud storage.

Description

technical field [0001] The invention relates to a distributed data redundancy backup technology in the technical field of cloud storage, in particular to a cloud storage method, an encoding storage method, a resource rapid positioning method and a system thereof. Background technique [0002] With the development of cloud computing, more and more enterprises and individual users begin to consider moving to the cloud. Outsource computing to cloud service providers, reduce infrastructure purchases, flexible expansion requirements, reduce the initial configuration and maintenance costs of IT, and only need to pay to cloud service providers on demand, injecting more energy into the development of enterprises New impetus. [0003] Cloud computing is prevalent all over the world, and the most important and popular cloud service is cloud storage service, such as Amazon's S3 and Microsoft's Azure storage service. Cloud storage provides users with data storage services, more and mo...
