Description

Method, apparatus and program for supporting reproduction of virtual machine images between multiple cloud platforms The present disclosure relates to a technology that supports replication of virtual machine images, specifically, to support replication of virtual machine images between multiple cloud platforms. A cloud platform is a platform that utilizes internet technology to provide highly scalable IT resources as a service to a large number of customers. Through a cloud platform, users can create virtual machines (VMs) and use them like a personal desktop environment. However, while the virtual machine image replication feature inherent to cloud platforms supports replication from a specific physical server to another physical server within the same cloud platform, it does not support replication to physical servers managed by different cloud platforms. These problems make it inconvenient for users to use virtual machines on cloud platforms, and new technologies and methods are required to resolve them. In this regard, Korean Published Patent Application No. 10-2024-0009546 discloses a business management system using a cloud computing-based platform. FIG. 1 is an exemplary diagram of a system for supporting replication of a virtual machine image between a plurality of cloud platforms according to one embodiment of the present disclosure. FIGS. 2 to 8 are flowcharts illustrating a method for supporting replication of a virtual machine image between a plurality of cloud platforms according to one embodiment of the present disclosure. FIG. 9 illustrates a brief and general schematic diagram of an exemplary computing environment in which embodiments of the present disclosure may be implemented. Various embodiments are now described with reference to the drawings. In this specification, various descriptions are provided to provide an understanding of the present disclosure. However, it is evident that these embodiments can be practiced without such specific descriptions. As used herein, terms such as “component,” “module,” “system,” etc. refer to computer-related entities, hardware, firmware, software, combinations of software and hardware, or executions of software. For example, a component may be, but is not limited to, a procedure executed on a processor, a processor, an object, an execution thread, a program, and/or a computer. For example, both an application executed on a computer device and the computer device itself may be a component. One or more components may reside within a processor and/or an execution thread. A component may be localized within a single computer. A component may be distributed among two or more computers. Additionally, these components may be executed from various computer-readable media having various data structures stored therein. Components may communicate through local and/or remote processes, for example, according to signals having one or more data packets (e.g., data from a component interacting with another component in a local system or distributed system, and/or data transmitted through signals to other systems and networks such as the Internet). Furthermore, the term "or" is intended to mean an implicit "or" rather than an exclusive "or." That is, unless otherwise specified or evident from the context, "X uses A or B" is intended to mean one of the natural implicit substitutions. In other words, if X uses A; if X uses B; or if X uses both A and B, "X uses A or B" may apply to any of these cases. Additionally, the term "and/or" as used herein should be understood to refer to and include all possible combinations of one or more of the enumerated related items. Additionally, the terms “comprising” and/or “comprising” should be understood to mean that such features and/or components are present. However, the terms “comprising” and/or “comprising” should be understood not to exclude the presence or addition of one or more other features, components and/or groups thereof. Furthermore, unless otherwise specified or clearly evident from the context to indicate a singular form, the singular in this specification and claims should generally be interpreted to mean “one or more.” And, the term “at least one of A or B” should be interpreted to mean “a case including only A,” “a case including only B,” or “a combination of A and B.” Those skilled in the art should recognize that the various exemplary logical blocks, configurations, modules, circuits, means, logics, and algorithmic steps described in connection with the embodiments disclosed herein may be implemented in electronic hardware, computer software, or a combination of both. To clearly exemplify the interchangeability of hardware and software, various exemplary components, blocks, configurations, means, logics, modules, circuits, and steps have been generally described above in terms of their functionality. Whether such functionality is implemented in hardware or software depends on the specific application and design
