These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0043] A cloud image is a copy of server data created in the cloud, mainly used to create fault-tolerant and redundant server computing infrastructure. In cloud computing, an image is a regional resource, and a private image belongs to the region where it is created. If you need to use a private image in another region, you can use the cross-region image replication function to achieve this.
[0044] However, cloud computing basic services need to be deployed separately on servers, which is often complex and difficult. In particular, most existing technologies only focus on the implementation of cross-platform image replication, and rarely focus on the simplification of the infrastructure and the embodiment of scalability. At present, users mainly download the image from the source cloud area and then upload it to the target cloud area to achieve image replication, which is extremely cumbersome.
[0045] For example, Figure 1 The following is a schematic diagram of an infrastructure as a service architecture provided by an embodiment of the present application. Figure 1 As shown in FIG. 1 , the central site of the Infrastructure as a Service (IAAS) architecture is connected to cloud regions A to E through switches. Figure 1 In the IaaS architecture shown, how to implement cross-cloud region private image replication while avoiding infrastructure complexity and solving problems such as inconvenience in expansion is a problem to be solved in cross-cloud region private image replication.
[0046] In order to solve the above problems, the present application provides a method for copying private images across cloud regions. Based on the existing IAAS infrastructure, the image copying across cloud regions is realized through the interaction between the orchestration system and the central site. Specifically, the orchestration system pulls the private image to the central site and modifies the status of the private image. When it is determined that the pull is complete, the orchestration system issues a distribution instruction to instruct the central site to copy the private image to the target area, thereby completing the copying of the private image. The present application implements the function of copying private images across cloud regions, realizes one-time system deployment, reduces the pressure on infrastructure services, reduces the cost and workload of infrastructure service deployment, and is conducive to the expansion of cloud architecture and the availability of cloud services.
[0047] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0048] Figure 2 A flowchart of a private image replication method across cloud regions provided for an embodiment of the present application. The execution subject of the embodiment of the present application may be a private image replication device across cloud regions, and the private image replication device across cloud regions may be located on an electronic device, and the electronic device may be a mobile terminal, such as a mobile phone, a tablet, a computer, etc., which is not limited by the present application. In the present application, the private image replication device across cloud regions may also be used as an orchestration system or a part of an orchestration system, and the image replication across cloud regions is realized by interacting with the orchestration system and the central site. The embodiment of the present application is described in detail by taking the execution subject as an orchestration system as an example.
[0049] like Figure 2 As shown, the cross-cloud region private image replication method provided by this embodiment includes:
[0050] S201. Obtain image copy request information; wherein the image copy request information includes image information of a target private image and region information of a target cloud region.
[0051] Exemplarily, when copying a private image across cloud regions, the orchestration system first receives an image copy request message. The image copy request message should at least include the image information of the target private image and the region information of the target cloud region. The original cloud region where the target private image is stored can be determined through the image information of the target private image, and the address of the destination to which the target private image will be copied can be determined through the region information of the target cloud region, and the destination is also the target cloud region.
[0052] S202: According to the image copy request information, pull the target private image to the central site, and modify the state of the target private image.
[0053] Exemplarily, after obtaining the image copy request information, the orchestration system of the present application pulls the target private image to the central site according to the image copy request information, and at the same time, modifies the status of the target private image. For example, before copying, the status of the target private image is "available", and during the process of executing the image copy, the status of the target private image is modified to "copying". The status of the target private image can also be represented by other words or symbols, which is not limited by the present application.
[0054] The present application does not limit how to pull the target private image to the central site according to the image copy request information. In one example, pulling the target private image to the central site according to the image copy request information may include:
[0055] S10: Parse the image copy request information to determine the image information of the target private image and the region information of the target cloud region.
[0056] S20. Determine the original cloud region of the target private image based on the image information of the target private image; wherein the original cloud region is the cloud region where the target private image is stored.
[0057] S30. Send a pull instruction to the central site; wherein the pull instruction is used to instruct the central site to pull the target private image from the original cloud area to the central site.
[0058] Exemplarily, the orchestration system parses the acquired image copy request information to determine the image information of the target private image and the regional information of the target cloud region; then, based on the image information of the target private image, the original cloud region of the target private image can be determined; then, the orchestration system sends a pull instruction to the central site to instruct the central site to pull the target private image from the original cloud region to the central site, so as to subsequently copy the target private image.
[0059] Among them, by issuing instructions to the central site to pull the target private image to the central site, instead of directly interacting with the cloud area under the central site, the complexity of the infrastructure can be reduced, and subsequent expansion is facilitated, thereby improving the scalability of the entire system.
[0060] For example, in some examples, before sending a pull instruction to the central site, it is also necessary to determine whether the target private image can be copied to the target cloud area to ensure the information security of the private image during the copying process. Therefore, the method of the present application may also include:
[0061] Based on preset permission rule information, determine whether the target private image stored in the original cloud area can be copied to the target cloud area; wherein the preset permission rule information is used to characterize whether the target private image stored in the original cloud area can be copied to the target cloud area.
[0062] Exemplarily, before sending a pull instruction to the central site, the orchestration system first retrieves the preset permission rule information that characterizes whether the target private image stored in the original cloud area can be copied to the target cloud area, and then determines whether the target private image stored in the original cloud area can be copied to the target cloud area based on the preset permission rule information. If it is determined that the target private image stored in the original cloud area can be copied to the target cloud area, a pull instruction is sent to the central site; if it is determined that the target private image stored in the original cloud area cannot be copied to the target cloud area, no pull instruction is sent to the central site. Among them, only when it is determined that the target private image stored in the original cloud area can be copied to the target cloud area based on the preset permission rule information, the instruction to pull the target private image from the original cloud area is sent to the central site, and the copying security of the private image is ensured by permission verification, and the private image is also ensured not to be abused.
[0063] In some examples, in order to further improve information security when copying a private image, after determining that the target private image stored in the original cloud area can be copied to the target cloud area, the following steps may also be included:
[0064] The target private image is encrypted so that the target private image is in an encrypted state.
[0065] Exemplarily, in order to ensure the information security of private images during the copying process, after determining that the target private image stored in the original cloud area can be copied to the target cloud area, the orchestration system can also encrypt the target private image to make the target private image in an encrypted state, thereby ensuring that the target private image pulled to the central site and the target private image subsequently copied to the target cloud area are both encrypted, thereby ensuring the information security of the private image copying process.
[0066] S203: If it is determined that the target private image is pulled successfully, a distribution instruction is issued to the central site; wherein the distribution instruction is used to instruct the central site to copy the target private image to the target cloud area based on the area information of the target cloud area.
[0067] Exemplarily, after issuing a pull instruction to the central site, the orchestration system monitors whether the target private image is pulled successfully. If the pull fails, it is determined that the private image copying has failed. If it is determined that the target private image is pulled successfully, the orchestration system further issues a distribution instruction to the central site to instruct the central site to copy the target private image to the target cloud area based on the regional information of the target cloud area, thereby completing the copying of the target private image.
[0068] In one example, determining that the target private image is successfully pulled may include:
[0069] If it is determined based on the scheduled monitoring task that the target private image exists in the central site, it is determined that the target private image is pulled successfully; wherein the scheduled monitoring task is a task for regularly monitoring the execution status of the image copy request information.
[0070] Exemplarily, in the process of executing the image copy task indicated by the image copy request information, the orchestration system is also used to periodically monitor the execution of the image copy task. If after issuing a pull instruction to the central site, based on the periodic monitoring task, it is determined that the target private image exists in the central site, it can be determined that the target private image is pulled successfully. After determining that the target private image is pulled successfully, a distribution instruction is issued to the central site to copy the target private image to the target cloud area, thereby completing the private image replication across cloud areas. If, based on the periodic monitoring task, it is determined that the pull of the target private image fails, it can be determined that the private image replication fails.
[0071] When it is determined that the private image replication fails, the status of the target private image can be modified to "replication failure" so that the user can determine the replication status of the private image through the status of the target private image.
[0072] In addition, when it is determined that the pull of the target private image fails, the central site can be set to repeat the pull instruction multiple times to pull the target private image multiple times, thereby improving the replication success rate of the target private image.
[0073] The cross-cloud region private image replication method provided by the embodiment of the present application includes: obtaining image replication request information; wherein the image replication request information includes the image information of the target private image and the region information of the target cloud region; according to the image replication request information, the target private image is pulled to the central site, and the state of the target private image is modified; if it is determined that the pull of the target private image is successful, a distribution instruction is issued to the central site; wherein the distribution instruction is used to instruct the central site to copy the target private image to the target cloud region based on the region information of the target cloud region. The solution of the present application realizes the function of cross-cloud region private image replication by interacting with the central site, realizes one-time system deployment, reduces the pressure on infrastructure services, and also reduces the cost and workload of infrastructure service deployment, which is conducive to the expansion of cloud architecture and increases the availability of basic services.
[0074] Based on the above embodiments, in some examples, the method of the present application may further include:
[0075] If it is determined that the target private image is successfully copied, the target private image is deleted from the central site and the state of the target private image is restored.
[0076] Exemplarily, when the central site copies the target private image to the target cloud region based on the regional information of the target cloud region, the target private image will be available in the target cloud region. When it is determined that the target private image is stored in the target cloud region, it is determined that the target private image has been successfully copied. If it is determined that the target private image has been successfully copied, the orchestration system can further delete the target private image from the central site to reduce the target private image's memory usage at the central site, and also prevent the target private image from being tampered with or leaked, thereby improving the information security of the target private image. In addition, the state of the target private image is also restored, for example, the state of the target private image is restored to "available" to facilitate the subsequent use of the target private image.
[0077] In some examples, the method of the present application may further include:
[0078] Each step of executing the image copy request information is recorded in a preset relational database. If it is determined that an abnormality occurs in the process of executing the image copy request information, a prompt message is sent to relevant personnel; wherein the prompt message is used to prompt relevant personnel about the image copy abnormality.
[0079] Exemplarily, the orchestration system may also record each step information of executing the image copy request information in a permanent preset relational database. Among them, the present application does not limit the preset relational database. For example, the preset relational database may be a MySQL database. After the orchestration system records each step information of executing the image copy request information in the preset relational database, it also performs data analysis on the recorded data. If it is determined that an abnormality occurs in the process of executing the image copy request information, a prompt message is sent to the relevant personnel to inform the relevant personnel of the image copy abnormality. The relevant personnel may include users, technicians, operation and maintenance personnel, etc., and can be set according to needs so that the relevant personnel can view and analyze the problem as soon as possible, thereby reducing the system maintenance cost and improving the efficiency of troubleshooting.
[0080] For example, Figure 3 A logical diagram of an orchestration system implementing mirror replication provided in an embodiment of the present application. Figure 3As shown, the orchestration system first obtains the image copy request information, and then pulls the target private image to the central site according to the image copy request information, and modifies the status of the target private image to "copying". Then, it is determined whether the target private image is pulled successfully. If it is determined that the pull is successful, a distribution instruction is issued to the central site to copy the target private image to the target cloud area; if it is determined that the pull fails, the copy fails, and the image status is modified to "copy failed"; after issuing the distribution instruction to the central site, it is further determined whether the target private image has been successfully copied to the target cloud area. If it is determined that the copy is successful, the target private image in the central site is deleted, and the status of the target private image is modified to "available"; if it is determined that the copy fails, the image status is modified to "copy failed". By interacting with the central site, private image replication across cloud regions is realized, and one-time system deployment is achieved, which reduces the pressure on infrastructure services, and also reduces the cost and workload of infrastructure service deployment, which is conducive to the expansion of cloud architecture.
