1 is a block diagram illustrating a configuration of a compressed image file management apparatus 100 of a cloud computing system according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the apparatus 100 for managing compressed image files of a cloud computing system according to an exemplary embodiment may include a user interface unit 110, a controller 120, a database 130, a file storage controller 140, and a file store. Server 150.

The user interface 110 is an interface for a user account of a cloud computing system, and is generally implemented in the form of a web-based user interface (UI), and virtual machines assigned to the user account from the user 160. Receives a user request including an upload request, a delete request, a file name change request, and the like, of a compressed image file to be installed in the.

User 160 is a user of an account that is assigned to use at least one or more virtual machines from the cloud computing system, if the user account is assigned to the company may be a cloud account administrator (Administrator) of the company.

The compressed image file is a compressed image file including at least one of an operating system or an application to be installed in the virtual machines assigned to the user account. In general, an ISO image file may be used, but the present invention is not limited thereto.

An ISO image file is a compressed file (disk image) of an optical disc established by the International Organization for Standardization (ISO) and generally has a file extension of ".iso". The name ISO is taken from the ISO 9660 file system for CD-ROM media, but the ISO image can also contain the UDF file system and is a digital copy containing all the file data contained in the disc format. In distributing such software, it is created for transmission over a network rather than a physical storage medium.

The control unit 120 receives a request for the compressed image file of the user 160 through the user interface unit 110, generates a control signal according to the request of the user based on the received request, and thereby generates a database ( 130 and the file storage control unit 140 and the like.

For example, when an upload request is received from the user, the controller 120 generates an authentication key for the user 160 so that the user can upload a compressed image file by forming a secure channel with the file storage control unit 140. When the authentication key generated through the unit 110 is transmitted to the user 160, and the user 160 uploads the compressed image file to the file storage control unit 140, the information of the compressed image file is transmitted to the database 130. Save it.

The file storage server 150 in the present embodiment is a network file system-based storage server, which is connected to the file storage controller 130 and stores and manages a compressed image file under the control of the file storage controller 130.

The file storage control unit 140 receives an authentication key from the control unit 120 to form a secure channel in the process of receiving a compressed image file from the user 160. The file storage control unit 140 compares the authentication key provided from the control unit 120 with the authentication key received from the user 160 to determine whether to allow the upload to the user 160. For example, it is preferable to allow upload of the corresponding user 160 only when the authentication key provided from the controller 120 and the authentication key received from the user 160 coincide with each other.

When the file storage control unit 140 allows the upload to the user 160, the file storage control unit 140 allocates a port for upload to the user 160 and receives the compressed image file from the corresponding user 160 through the assigned port. .

If the upload request is allowed in the file storage control unit 140, the controller 120 obtains the information of the compressed image file from the upload request of the corresponding user 160 that is allowed to upload and stores it in the database 130.

In this embodiment, an index value is assigned in storing the information of the compressed image file. In order to assign an index value, serial numbers may be sequentially assigned so as not to overlap each other.

In addition, in order to facilitate retrieval, in storing the compressed image file in the file storage server 150 in the file storage control unit 140, the file storage control unit 140 indexes the file name of the compressed image file in the database 130. You can change it to match the value.

The compressed image file management apparatus 100 according to the present embodiment is a component installed in a cloud computing system and includes at least one digital signal process (DSP) processor, a controller, an application specific integrated circuit (ASIC), and a field programmable gate (FPGA). programmable logic elements such as arrays), other electronic devices, or combinations thereof. In addition, at least some of the components and functions of the compressed image file management apparatus 100 according to the present embodiment may be implemented in software, and such software may be recorded in a recording medium. In addition, each component and function of the compressed image file management apparatus 100 according to the present embodiment may be implemented by a combination of hardware and software.

Referring to FIG. 2A, first, a user 260 requests an upload of an ISO file including an operating system or an application to be installed in its account on the user interface server 210 (S201).

The user interface server 210 receives the ISO file upload request received in step S201 and transfers it to the control server 220 to request generation of an authentication key for the corresponding user 260 (S202).

The control server 220 generates an authentication key for the corresponding user 260 according to the request sent in step S202, and distributes it to the user interface server 210 and the file upload server, respectively (S203-1, S203-2). ).

The user 260 receives the authentication key for uploading the ISO file through the user interface server 210 (S204), and uploads the ISO file through the secure channel formed on the basis of this (S205).

The control server 220 obtains the information of the ISO file to be uploaded by the user from the request sent in step S202, and sequentially assigns index values (270, see FIG. 2B) of serial number format to the ISO file so as not to overlap each other. .

The control server 220 stores the information of the ISO file in the database server 230 using the sequentially assigned index value as the primary key (S206).

The file upload server 240 changes the file name of the compressed image file received through the step S205 to the index value assigned by the control server 220 (see FIG. 2B and FIG. 2B), and compresses the compressed image file to the file storage server 250. It is stored (S207). The file upload server 240 may be implemented in the form of a virtual machine that receives and uses virtualized computing resources in a cloud computing system. In this case, the file storage server 250 is implemented based on a network-based file system and is a file upload server. Mounted at 240 may be implemented to receive control of the input and output of the file from the file upload server 240.

3 is a diagram illustrating a process of deleting an ISO file according to a user's deletion request in a cloud computing system according to an exemplary embodiment of the present invention.

Correspond to the user interface unit 110, the control unit 120, the database 130, the file storage control unit 140 and the file storage server 150 of the compressed image file management apparatus of the ISO file according to the present embodiment. The deleting process may be implemented in the compressed image file management apparatus 100 of the cloud computing system illustrated in FIG. 1. Therefore, the same matters as in the description of the compressed image file management apparatus 100 of the cloud computing system illustrated in FIG. 1 are referred to this.

Referring to FIG. 3, first, the user 360 requests a deletion of a previously stored ISO file previously uploaded on the user interface server 310 (S301).

The user interface server 310 transmits a request for deleting the pre-stored ISO file of step S301 to the control server 320 (S302).

The control server 320 obtains the information of the pre-stored ISO file requested to be deleted from the delete request transmitted in step S302, and searches for the information of the pre-stored ISO file on the database server 330 based on the information, and assigns the pre-stored ISO file to the prestored ISO file. After finding the index value, the information of the previously stored ISO file is deleted from the database server 330 (S303).

The index value of the pre-stored ISO file found in step S303 is sent to the file upload server 340 (S304).

The file upload server 340 deletes the pre-stored ISO file from the file storage server 350 based on the index value of the pre-stored ISO file received through step S304. According to the present exemplary embodiment, the file name of the pre-stored ISO file may be implemented to match the index value of the pre-stored ISO file, and thus it may be easily implemented for searching and deleting.

In this embodiment, since the ISO file or other information is not received after the deletion request is received from the user, separate authentication for forming a secure channel with the user in the control server 320 is different from the embodiment shown in FIG. 2. It does not generate a key.

4 is a diagram illustrating a process of changing a file name of a compressed image file according to a file name change request of a user in a cloud computing system according to an exemplary embodiment of the present invention.

Therefore, the same matters as in the description of the compressed image file management apparatus 100 of the cloud computing system illustrated in FIG. 1 are referred to this.

Referring to FIG. 4, first, the user 460 requests a file name change of a previously stored ISO file previously uploaded on the user interface server 410 (S401).

The user interface server 410 transmits a file name change request of the pre-stored ISO file in step S401 to the control server 420 (S402).

The control server 420 acquires the information of the prestored ISO file requested for the file name change from the file name change request transmitted in step S402, and searches the information of the prestored ISO file on the database server 430 based on the information. Correct the file name information of the previously stored ISO file to a new file name desired by the user (S403).

In the present embodiment, where the ISO file is actually stored, the file name of the ISO file is changed to an index assigned by the cloud computing system so as not to overlap each other and stored. There is no need to change the information directly, but it is sufficient to change the information on the ISO file, for example, a database that stores metadata such as an index, a file name, and an uploaded user identifier.

In addition, since the present embodiment does not receive the ISO file or receive other information after receiving the file name change request from the user, unlike the embodiment shown in FIG. 2, the control server 420 may form a secure channel with the user. It does not generate a separate authentication key.

According to the present invention, a user of each account of the cloud computing system is assigned to each account of the cloud computing system so that the user does not have to go through the cumbersome procedure of manually installing an operating system or an application required to run the virtual machine in the initialized virtual machine instance. The compressed image file including the operating system or the application to be installed in the virtual machines can be uploaded in advance for efficient management.
