Embodiment Construction

[0040] Such as image 3 As shown, the present invention is based on cloud-mist collaborative multi-cloud storage system, including:

[0041] Multiple clients (1), used to send user registration, login and file operation requests to fog computing nodes;

[0042] The fog computing node (2) is used to perform user authentication and authorization for the client, manage file metadata, cache data in the local database, perform data reduction and secure encoding processing on the file, and forward the encoded file data to the cloud storage service;

[0043] Multiple cloud storage services (3) are used to provide remote online network storage rental services, and perform file access operations through standard application programming interface APIs, such as Put, Get, Create and Delete operations;

[0044] The fog computing node (2) is adjacent to the client (1), the fog computing node (2) is interconnected with each client (1) through network communication, and the cloud storage ser...

Abstract

The invention discloses a multi-cloud storage system based on cloud and fog cooperation and a management method thereof. The multi-cloud storage system based on the cloud and fog cooperation and the management method thereof are high in service availability, good in access performance, low in storage cost and high in data security. The multi-cloud storage system comprises a plurality of clients (1), fog computing nodes (2) and a multi-cloud storage service (3), wherein the fog computing nodes (2) are adjacent to the clients (1), the fog computing nodes (2) are in communication interconnectionwith the clients (1) through a network, and the multi-cloud storage service (3) is far away from the fog computing nodes (2) and the clients (1) and is in communication interconnection with the fog computing nodes (2) through a remote network. The method comprises the processing steps of (10) sending an access request, (20) authenticating the access request, (30) reducing file data, (40) performing file security fault-tolerant coding, (50) sending coded file fragments, (60) receiving file fragment processing, (70) migrating cloud storage service and (80) deleting files.

Description

technical field [0001] The invention belongs to the technical field of distributed computing and cloud storage, in particular to a highly reliable, high-performance, high-safety and low-cost cloud-fog collaborative multi-cloud storage system and a management method thereof. Background technique [0002] With the development of informatization and digitization year by year, people's demand for data storage is increasing. In the case of rapid data growth, local storage solutions can no longer meet the needs of users. The emergence of cloud storage provides users with pay-as-you-go scalable online storage services, and can also facilitate data management and maintenance, and can help solve local problems. Storage encounters problems such as non-expandable capacity, inconvenient portability, and difficulty in data loss recovery. However, if the user only stores data in a cloud storage service provider, it will not only make the user dependent on it, but also cause the cloud pla...
