Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

Fig. 1 is a schematic diagram showing an architecture of a processing apparatus for a batch file in the related art.

As shown in fig. 1, a processing apparatus for batch files in the prior art includes: a batch file sending module 110, an SFTP interface machine 120 in a main-standby mode, and a background storage module 130.

The bulk file sending module 110 includes at least one service file, which is not limited herein, for example: service file 1, service file 2, service file 3 … …, service file n, etc. The batch file sending module 210 is used to transmit the service file 1, the service file 2, the service file 3 … …, the service file n, etc. to the corresponding server. For example: the service file 1 corresponds to the server 1, the service file 2 corresponds to the server 2, the service file 3 corresponds to the server 3, and the like. The service file in the server is stored in the background storage module 120.

Due to the fact that one service file corresponds to one server, real-time synchronization needs to be achieved through deployment of a large number of SFTP interface machines, deployment is complex, and once the SFTP interface machines fail and cannot be started normally, data consistency of the background storage module 130 cannot be guaranteed.

In addition, the storage of the SFTP interface machine adopts a built-in disk partitioning raid mode, so that a data protection mechanism is insufficient, the reliability is not high, and the disk IO of a single server is limited. And because the SFTP interface machine adopts the main standby mode, the standby machine is idle more, and the waste of resources is caused. The service allocation can not be flexibly carried out according to the busy degree of the SFTP interface machine, and the resources can not be reasonably utilized.

Therefore, the processing device for batch files provided by the embodiment of the invention adopts the distributed SFTP gateway and the uniform access IP interface, so that not only is the deployment simple, but also the simultaneous transmission of a large number of files can be realized. In addition, or according to the number of the service files, service distribution is flexibly carried out, and resources are reasonably utilized.

For a better understanding of the present invention, apparatuses, methods, devices, and media for processing batch files according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.

Fig. 2 is a schematic diagram illustrating an architecture of a batch file processing apparatus according to an embodiment of the present invention.

As shown in fig. 2, the apparatus 200 for processing the batch file includes:

the system comprises a batch file sending module 210, a distributed SFTP gateway 220 and a distributed cloud array storage module 230.

The bulk file sending module 210 includes at least one service file, which is not limited herein, for example: service file 1, service file 2, service file 3 … …, service file n, etc. The bulk file sending module 210 is used to transmit the service file 1, the service file 2, the service file 3 … …, the service file n, etc. to the distributed SFTP gateway 220.

The distributed SFTP gateway 220 adopts a uniform access IP interface inside, and solves the problems that an interface server corresponds to an access IP address to generate a large amount of access IP, so that the access IP address is complex and the uniform management difficulty is increased. The invention adopts a uniform access IP interface to reduce the complexity of service access, so that the management becomes simple. In addition, the method can meet the service requirement of uploading a large number of data files in time, thereby avoiding resource waste and being beneficial to flexible allocation of storage resources.

The distributed SFTP gateway 220 receives a plurality of SFTP protocol files through the unified access IP interface, converts the plurality of SFTP protocol files by using an S3 protocol, and directly and transparently transmits the plurality of S3 protocol files obtained by conversion to the distributed cloud array storage module 230.

It should be understood that transparent transmission is transparent transmission, which means that the transmission network is only responsible for transmitting the service to be transmitted to the destination node no matter how the service is transmitted, and at the same time, the transmission quality is ensured, and the transmitted service is not processed. During the data transmission process, the group of data is not changed in any form, i.e. is not truncated, is not grouped, is not encoded, is not encrypted, is not confused, and the like, and is directly transmitted to the distributed cloud array storage module 230.

The distributed SFTP gateway 220 directly passes through the converted S3 protocol files to the distributed cloud array storage module 230. The distributed SFTP gateway 220 does not have S3 protocol file left therein, so that the storage pressure of the distributed SFTP gateway 220 on the protocol file is directly reduced, and therefore, the distributed SFTP gateway 220 can be installed in a light weight manner. In addition, the load of the distributed SFTP gateway 220 is reduced, the performance consumption is greatly reduced, the horizontal expansion is easier, the security is better, the batch configuration management is easier, and the increasing business data storage requirement and the emergency capacity expansion requirement are easier to meet.

The distributed cloud array storage module 230 processes the plurality of S3 protocol files by using an erasure code technology thereof, and stores the processed plurality of S3 protocol files.

It should be appreciated that Erasure Coding (EC) is a method of data protection that partitions data into fragments, expands, encodes, and stores redundant data blocks in different locations, such as disks, storage nodes, or other geographic locations. Therefore, in the embodiment of the present invention, the distributed cloud array storage module 230 divides each S3 protocol file into segments, expands, encodes, and stores redundant data blocks in different locations. This enables the protocol files to be better stored at the respective storage nodes. Meanwhile, the lateral expansibility of the distributed cloud array storage module 230 is improved, so that the increasing storage requirement and the emergent capacity expansion requirement of the service files are met.

The embodiment of the invention reduces the complexity of service access and simplifies the management by adopting the distributed SFTP gateway 220. In addition, the method can meet the service requirement of uploading a large number of data files in time, avoid the condition of resource waste and is favorable for flexibly allocating storage resources. Meanwhile, due to the adoption of the distributed cloud array storage module 230, the files can be better stored in the corresponding storage nodes. And the lateral expansibility of the distributed cloud array storage module 230 is improved, so that the increasing business file storage requirement and the urgent capacity expansion requirement are met.

In one embodiment, the distributed SFTP gateway 220 includes: a plurality of servers and an access account rights management unit 222.

Each server is used for receiving the SFTP protocol file through the unified access IP interface, converting the SFTP protocol file by using an S3 protocol, and directly transmitting the converted S3 protocol file to the storage node corresponding to the distributed cloud array storage module 230.

And an access account authority management unit 222, configured to uniformly manage access account authority of the service process of each server.

It should be noted that, the distributed SFTP gateway 220 may include at least 1 server, such as: server 1, server 2, server 3 … …, server n, etc., which directly transmit the converted multiple S3 protocol files to the distributed cloud array storage module 230. Therefore, the S3 protocol file does not stay in the server, the storage pressure of the distributed SFTP gateway 220 on the protocol file is directly reduced, and the server can be installed in a light weight mode. In addition, the load of the server is reduced, the performance consumption is greatly reduced, the transverse expansion is easier, the safety is better, the batch configuration management is easier, and the increasing business data storage requirement and the emergent expansion requirement are easier to meet.

The access account authority management unit 222 collectively manages access account authority of the service process of each server. The access account authority management unit 222 is mainly used for unified management of access account authority of SFTP users, and performs overall evaluation and use according to requirements of the SFTP users, and performs corresponding security restrictions. The access account authority management unit 222 may record an operation log, and the operation log records a backtrack, where the operation log records detailed operations of the SFTP user on the file, including operations of uploading, downloading, deleting, and moving the file.

The tracking and administration of SFTP user operations by the access account rights management unit 222 is facilitated. Meanwhile, the problems of complex account number access, high account number management difficulty and high risk caused by using a large number of SFTP interface machines in the prior art are also solved.

In addition, because the access authority of the storage node in the distributed cloud array storage module 230 corresponds to the access account authority in the access account authority management unit 222, the unified management of the access authority of the distributed cloud array storage module 230 is realized, and the management efficiency is greatly improved. For example: the user a logs in the access account authority management unit 222 to input its own service file account PA _ ID, and can directly access the corresponding server a through the PA _ ID, and then corresponds to the access authority of the storage node a through the PA _ ID, so that the data file in the storage node a can be directly accessed through the PA _ ID.

In one embodiment, one storage node corresponds to the service processes of any two servers.

It is understood that, for example: the service processes of the server 1 and the server 2 correspond to a storage node a.

It can be understood that a storage node at one back end corresponds to service processes of two servers one to one, and the service processes of the distributed SFTP gateway 220 correspond to the back-end distributed cloud array storage module 230.

FIG. 3 is a schematic diagram showing a processing apparatus for processing a batch file according to another embodiment of the present invention.

Steps in fig. 3 that are the same or equivalent to those in fig. 2 are given the same reference numerals. As shown in fig. 3, the processing apparatus 300 is substantially the same as the processing apparatus 200, except that the processing apparatus 300 further includes: a verification module 240 and a background database module 250.

And the verification module 240 is configured to receive the upload success information sent by the batch file sending module 210, verify the plurality of S3 protocol files acquired from the distributed SFTP gateway 220, and store the successfully verified S3 protocol files in the background database module 250. In an example, the verification module 240 is further configured to send the S3 protocol file that failed verification back to the distributed SFTP gateway.

And the background database module 250 is used for storing a plurality of S3 protocol files which are successfully verified.

By verifying the protocol file by the verification module, the protocol file with errors is corrected in time, so that the storage amount of the background database module 250 is reduced or the error rate of the protocol file stored in the background database module 250 is reduced.

Except for the distributed SFTP gateway 220 described in all embodiments above.

Distributed SFTP gateway 220 may also contain application component units, data component units, load balancing component units, and the like. In the embodiment of the present invention, the application component unit and the data component unit are separately deployed according to a security domain partitioning rule, the application component unit is deployed in a DMZ region of the distributed SFTP gateway 220, and the data component unit is deployed in an intranet core region of the distributed SFTP gateway 220.

The operating systems of the servers in the distributed SFTP gateway 220 are all installed in a light weight mode, so that the distributed SFTP gateway is low in load, low in performance consumption, easy to expand transversely, good in safety and easy to configure and manage in batches. The security domain division rule achieves all-around protection of the user and the distributed SFTP gateway 220 in terms of protocol conversion according to different service files, different users and the combination of the distributed SFTP gateway 220, and actual requirements of the user are met.

The rights management unit 222 is also used to manage the system user, which is separate from the SFTP user, with respect to the access account. The system user is used for maintaining and supervising the daily operation of the SFTP user; the SFTP user can maintain the interface of the system user management uniformly, such as: and setting the authority, configuring a root directory to a bucket stored in the object, and setting the access authority to a folder under the specified bucket. By means of the account number access authority management mode, the protocol file is safer.

It is understood that the distributed SFTP gateway 220 directly passes the converted S3 protocol files directly to the distributed cloud array storage module 230. The distributed SFTP gateway 220 does not have S3 protocol file left therein, so that the storage pressure of the distributed SFTP gateway 220 on the protocol file is directly reduced, and therefore, the distributed SFTP gateway 220 can be installed in a light weight manner. In addition, the load of the distributed SFTP gateway 220 is reduced, the performance consumption is greatly reduced, the horizontal expansion is easier, the security is better, the batch configuration management is easier, and the increasing business data storage requirement and the emergency capacity expansion requirement are easier to meet.
