Problems solved by technology

[0015] The present invention aims at the problems of low utilization rate of storage space, large amount of redundancy, high load of network communication, and long response time to services in the existing cloud storage method, and proposes a redundant coding method based on Vandermonde matrix and a resource fast method based on Chord ring. The positioning method, combined with the specific operation process of cloud storage, realizes a cloud storage solution with high availability, low redundancy and fast response

specific Embodiment approach

[0031] 1. The overall architecture of the high-availability cloud storage method:

[0032] As shown in the figure, the overall architecture of this solution consists of the following parts: a cloud storage operation module on the user side, a storage data processing module on the cloud storage server side (including data storage, data recovery, and data modification), and a data encoding and decoding module. The user submits the file operation he needs to the cloud storage service, and the cloud storage service parses the user's request and makes a specific response. The storage data processing module on the server side mainly deploys 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 the scheme. Enough redundant items can be generated by encoding the data to ensure the high availability o...

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 field of cloud storage technology, 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 are considering moving to the cloud. Outsourcing computing to cloud service providers, reducing their own infrastructure purchases, flexible scaling requirements, reducing the initial IT configuration and post-maintenance expenses, only need to pay cloud service providers on demand, injecting into the development of the enterprise New motivation. [0003] Cloud computing prevails all over the world, and the most important and popular cloud services are cloud storage services, such as Amazon's S3 and Microsoft's Azure storage service. Cloud storage provides users with data storage services. More and more ...
