Problems solved by technology

[0018] From the above steps, it can be seen that the hierarchical directory structure in the traditional file system provides users with flexible and convenient data access methods, but it does not specifically optimize the data "once written and no longer changed" in the cloud computing environment. , the functions of file addressing, file opening and closing, and file read-write lock mechanism all have a great impact on system performance, so the efficiency is not high

Embodiment Construction

[0064] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] like figure 2 As shown, the massive data access method in the cloud computing environment of the present invention is applied to the Linux operating system, and a Configurable Block File System (hereinafter referred to as CBFS) can be realized. The relationship between the configurable block file system and other related modules in the operating system kernel is as follows: figure 2 As shown, it directly reads and writes disk data through a disk drive, without using a virtual file system or a traditional file system, and the steps are simpler and more efficient than traditional data access methods.

[0066] like image 3 , Figure 4 , Figure 5 , Image 6 As shown, the massive data access method under the cloud computing environment of the present invention includes the following steps:

[0067] 1. Format the disk partiti...

Abstract

The invention discloses a method for accessing mass data in a cloud calculation environment. The method comprises the following steps of: formatting a disk partition and setting partition element data information which is updated in real time with user operation into the disk partition; and writing data blocks which are processed by a data management system in an application layer into the disk partition one by one and indexing the data blocks sequentially, wherein a user reads the corresponding data blocks from the disk partition according to the input index numbers. The method has the advantages that: the steps are extremely simple, the data accessing efficiency in the cloud calculation environment is improved, the consumption of kernel resources of the system is reduced, the system performance is enhanced and the like.

Description

technical field [0001] The invention relates to a data management method in the computer field, in particular to a massive data access method in a cloud computing environment. Background technique [0002] Cloud computing is a business computing model that distributes computing tasks on a resource pool composed of a large number of computers, enabling various applications to obtain computing power, storage space and information services as needed; for data-intensive services, massive data Store in the cloud, extract some data on demand when the user needs it, and return the calculation result to the user. It integrates various resources in the network to provide services for users. Users can access and pay according to their needs, which is as convenient and fast as water and electricity. With the rapid development of information technology, cloud computing has become a trend. [0003] like figure 1 As shown, the existing data management methods for cloud computing enviro...
