Problems solved by technology

[0008] The second is the question of copy placement selection
The cloud storage system based on the HDFS architecture is randomly selected when selecting the copy placement, so the communication cost of user access is not considered

Embodiment Construction

[0061] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 as shown, figure 1 It is a system structure diagram of copy dynamic control oriented to a cloud computing platform; a system of copy dynamic control oriented to a cloud computing platform includes a user agent module, a monitoring system and a data storage system.

[0063] The monitoring system includes a replica placement module, a replica monitoring system and a replica deletion module; the replica monitoring system sends information to the replica placement module and the replica deletion module respectively, and the replica placement module and the replica deletion module respectively send information to the user agent module; the user agent module sends information to the copy monitoring system.

[0064] The data monitoring system includes a copy node and a backup copy node corresponding to the copy n...

Abstract

The invention provides a method and system for ectype dynamic control for a cloud computing platform. The method comprises the following steps that a minimum usable rate Rexp of ectypes is set; the minimum number rmin of the ectypes is obtained in the unit time t; whether waste of system resources exists or not is judged; a cost series from ectype nodes to standby ectype nodes is obtained; the standby ectype nodes used for containing the ectype nodes are obtained; the ectypes are duplicated to the standby ectype nodes. The method and system are used for improving the reliability and the usability of data in cloud computing and enabling balance between the usability and the cost to be achieved.

Description

technical field [0001] The invention relates to a method in the field of distributed computing and cloud computing, in particular to a cloud computing platform-oriented replica dynamic control method and a system thereof. Background technique [0002] With the development of computer technology and network technology, the scale of the Internet continues to expand, and the network bandwidth continues to increase. With the rapid development of the Internet, all kinds of information are collected in it, forming a huge and vast information space, and massive data are stored in this space. [0003] Traditional centralized storage systems store data on a single device through which all access and requests for data pass. This approach causes a large load on the device and becomes a bottleneck of the system, which cannot meet the reliability and security requirements of large-scale storage. How to store these data so that users can quickly and efficiently find and obtain the resou...
