It has the computing properties to pay. According to the type of service provided, it is divided into SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service) models. Among them, IaaS is a type of service that manages CPU resources, memory, disk, and network environments, which are major infrastructure resources for providing IT services, in the form of shared resources and provides them in a shared form. It is a form of using services by installing database and web server, which are middleware, and virtualizes and distributes hardware resources mainly using virtualization technology.

Referring to FIG. 3C , the overall structure of a system according to an embodiment of the present invention is shown, and detailed functions are defined as follows.

<Namespace Manager>

Namespace is a concept that specifies which namespace objects belong to. If an object with the same name belongs to a different namespace, objects with the same name can be distinguished by specifying the namespace. Objects for the user's MCIR and MCIS are logically separated through the namespace, so objects that can be searched and controlled vary according to the specified namespace. For example, you can isolate the MCIR and MCIS of each project by specifying a different namespace for each user's project. The namespace manager provides management functions so that users can create, inquire, and delete namespace objects.

A system according to an embodiment of the present invention provides a user with a function of creating, inquiring, and deleting a namespace object. The namespace object creation function creates an information object with the name of the namespace requested by the user and the universally unique identifier (UUID) information generated by the system. The user can check the entire list of namespaces through the namespace object lookup function, and can specify the UUID through the name of the namespace. The specified UUID is basic information required for inquiry and control requests for MCIR and MCIS. To delete the namespace object, the function to delete the namespace object checks information on MCIR and MCIS included in the namespace, and if there is an MCIR or MCIS included in the namespace, check not to allow the deletion of the namespace carry out When deleting a namespace, both MCIR and MCIS designating the namespace must be removed in advance.

<MCIR Manager>

The system according to an embodiment of the present invention provides a function for centrally managing cloud infrastructure resources used by each cloud to provide infrastructure services. Since the infrastructure resources of each cloud are used for the configuration and setting of MCIS, they need to be managed as objects.

Resources related to virtual machine access include a network security group (item group that designates an accessible network port) and an access security key (Key Pair) for accessing the virtual machine through SSH.

<MCIS Provisioning Manager>

The MCIS provisioning manager manages all procedures for creating MCIS. To create MCIS, virtual machines that become components of MCIS must be created, and the created virtual machines must be set and included in a logical object called MCIS. To create individual virtual machines, virtual machines are optimally placed and scheduled, and the optimal MCIS is provisioned to users by selecting virtual machines that optimally meet the service requirements of the MCIS unit.

The construction unit 310 may build an environment for the MCIS by setting and allocating at least one multi-cloud infrastructure resource (MCIR) provided to generate and operate the MCIS.

The input unit 320 may receive at least one request of the user terminal 100 . The user terminal 100 inputs at least one type of requirement to use the MCIS (Multi-Cloud Infra Service), and at least one virtual machine through optimal arrangement scheduling corresponding to the at least one type of requirement. (400) may be supported.

The providing unit 340 may provide the MCIS to the user terminal 100 . At this time, in desktop, laptop, cluster, and cloud environments based on heterogeneous resources such as GPU (Graphics Processing Unit) and SSD (Solid-state Drive), GPU performs superior computational work than CPU (Central Processing Unit) through massive parallel processing. And, due to these characteristics, it can be applied including GPU resources even in the cloud. Through virtualization, a core technology of the cloud, heterogeneous resources such as GPUs can be virtualized to increase the speed of computationally intensive and computational applications.

At this time, since the provision result varies according to application characteristics, application profiling and identification of heterogeneous resource information are required first. Even for applications with many computational tasks, the results of single GPU and multi-GPU differ depending on the scope of provision, and it is important to provide an environment with different execution resources in a heterogeneous cloud environment according to the characteristics of these applications. In this case, it is possible to use an execution environment management structure capable of effectively providing provision according to application characteristics and provision scope on heterogeneous resources.

In the CPU-GPU resource environment, it is possible to derive an efficient execution environment according to various provision ranges for deep learning applications and use it for scheduling and prediction of heterogeneous resource execution environment according to changes in the provision environment. In order to reconsider the necessity of determining the resource selection according to the conditions of the scope of application, the conditions necessary for selecting the execution environment can be derived by selecting a computationally intensive and CPU-GPU usable CNN (Convolutional Neural Network) model as an application.

Through the interface, the user submits a job, and the job submission creates a job according to the parameters and size of the application. This information is recorded in the application information, and based on this record, a resource suitable for the task is selected. Resource configuration and provision environment are created according to the application scope. The provision environment can be created based on CPU and GPU information of virtual resources and bare resources, and node resources are configured by recognizing each resource from the resource management module. You can configure the CPU or CPUGPU environment. A Docker container-based virtual execution resource has been built, and the resource management module is mesos (mesos 1.1.0), the task scheduler is chronos, and the container including GPU can utilize Nvidia Docker. In the same case of parallel and computation-intensive applications, GPU resources can be selected, and the number of GPU resources can be selected by determining the size of the application range.

The system 1 according to an embodiment of the present invention collects network delay information between virtual machines 400 across multiple clouds, and satisfies the network response speed of all virtual machines 400 in MCIS requested by a user within a specific ms. It provides a batch function that makes

Figure 4a shows an example of the network response speed-based arrangement between the virtual machines (400). If a mutual network response speed of less than 40 ms is specified in MCIS, the MCIS integration optimal arrangement function optimally configures MCIS only with virtual machines 400 that satisfy the constraint through network response speed information between virtual machines 400 . In addition, the system 1 according to an embodiment of the present invention provides the following algorithms as an optimal arrangement condition of each virtual machine 400 for optimal configuration of MCIS.

The virtual machine 400 specification-based placement is to perform recommendations and placement based on the specifications of the virtual machine 400 requested by the user, and the virtual machine 400 location-based placement is optimal in order of proximity to the region requested by the user. Recommendation and placement of the virtual machine 400 of and placement, and the virtual machine 400 performance-based placement determines the recommendation and placement of the virtual machine 400 based on the performance criteria requested by the user using information provided through the MCIS placement information collection function (performance benchmarking, etc.) will do Examples of performance factors of the virtual machine 400 may include computational performance, memory read/write performance, file IO performance, and the like. The virtual machine 400 complex condition-based arrangement is an algorithm that can be used when several factors need to be considered complexly, which can be implemented through a weighted sum of other algorithms (a formula that can express the user's preference for each algorithm). can

4) Create MCIS

It is a function of creating an MCIS object and generating the virtual machine 400 included therein through the virtual machine 400 creation function of the multi-cloud infrastructure interworking framework. The step of creating each virtual machine 400 can be largely divided into two steps: a creation request and a creation setting. After all the virtual machines 400 requested by the user are created, creation and access information for the virtual machines 400 corresponding to the MCIS object is input and returned to the user. Thereafter, the MCIS lifecycle manager manages the lifecycle for the new MCIS.

Returning to FIG. 2 again, the life cycle management unit 360, after the MCIS is provisioned to the user terminal 100, to perform management and control of the life cycle corresponding to the state of the MCIS, at least one virtual A life-cycle state of the machine 400 may be managed.

At this time, the lifecycle state is an operating state in which MCIS operates (Running), a suspended state in which MCIS is stopped (Suspended), a failure state in which MCIS is stopped due to an error (Failed), and an end state in which MCIS is terminated ( Terminated), the intermediate state in which MCIS is created, the creation progressing state, the intermediate state for suspending the MCIS, the Suspending state, and the intermediate state for re-executing the MCIS. Transition State including Resuming, which is a state of rebooting MCIS, Rebooting, and Terminating, which is an intermediate state that is executing the type of MCIS. can

Referring to FIG. 4B , after the MCIS is created and provisioned to the user, the life cycle management unit 360 provides a management and control function for the life cycle of the corresponding MCIS, that is, the state of the MCIS. MCIS lifecycle states such as operation state, stop state, and end state are managed for each MCIS and the included virtual machines 400, and the lifecycle of the MCIS managed by the system 1 according to an embodiment of the present invention It checks and synchronizes whether the life cycle of the real virtual machine 400 managed by the CSP and the CSP is the same. In addition, when a user requests a control related to the life cycle, it includes a function to perform it. The life cycle of MCIS is expressed as a comprehensive state of internal resources.

However, since the states of all detailed resources do not match one, it is necessary to provide a concept that can grasp the overall state without directly checking the detailed state. MCIS lifecycle provides partial state information. Partial state examines the state of internal resources of MCIS and displays the lifecycle as a representative state. For example, in the case of MCIS composed of 20 virtual machines 400, if more than 50% of the virtual machines 400 are in Running state, the MCIS life cycle state is Partial-Running state. When all virtual machines 400 are in the Running state, the MCIS lifecycle state is changed to Running. However, if even one virtual machine 400 in MCIS is in a Failed state, the MCIS life cycle is displayed and provided as Failed so that the Failed state of the virtual machine 400 can be immediately identified even in the MCIS unit.

The VPN unit 370 allocates a private IP (Private IP) using a VPN (Virtual Private Network) when at least one virtual machine 400 constituting the MCIS exists in different subnet network environments. By doing so, it is possible to configure the same subnet network between at least one virtual machine 400 .

The MCIS-specialized service provides a multi-cloud environment-specific service to compensate for the shortcomings in the utilization of MCIS composed of locally distributed virtual machines 400 as shown in FIG. 4C . MCIS specialized service consists of MCIS same subnet environment configuration function (MC-VPN) and MCIS load balancing function (MC-LB), and additional expansion is possible if necessary. The MCIS-specialized service can be selected when the user requests for MCIS deployment, and according to the user's choice, after MCIS deployment is completed, the same subnet environment is configured based on MCIS or load balancing is applied to specific virtual machines 400 . The detailed functions of these MCIS specialized services are as follows.

The MCIS same subnet environment configuration (MC-VPN) is a configuration performed by the VPN unit 370 . In the case of heterogeneous cloud-based MCIS, the virtual machines 400 constituting the MCIS can communicate only using a public IP (Public IP) due to different subnet bands. When an application program is operated based on such an environment, communication security problems may occur, and operation of a specific distributed application may not be possible due to other subnet problems. The MCIS same subnet configuration function (MC-VPN) configures the same subnet environment in MCIS by applying VPN technology to solve the network problem in such a multi-cloud environment, as shown in Figure 4d, and a heterogeneous cloud virtual machine 400 It functions to improve the security of communication between the two. When the user selects MCVPN configuration as an option when deploying MCIS through the MCIS creation function of the system 1 according to an embodiment of the present invention, all virtual machines ( 400) of the same subnet is allocated to the same subnet network environment between the virtual machines 400 .

The load balancing unit 380, in addition to at least one virtual machine 400 constituting the MCIS, when there is load balancing among at least one type of requirement input from the user terminal 100, a load balancing virtual machine 400 ) can be added. In this case, the virtual machine 400 for load balance may be a virtual machine 400 positioned to satisfy a preset regional separation condition from at least one virtual machine 400 constituting the MCIS.

In the MCIS 5 service operated in the multi-cloud environment, it is difficult to distribute the load on the MCIS configuration virtual machines 400 through the load balancing service provided by the individual CSP. The MCIS load balancing function provides a load balancing function between clouds in a heterogeneous multi-cloud environment. The MCIS load balancing function (MC-LB) is a function for reducing response time and improving the availability of MCIS by distributing the load for virtual machines 400 that are geographically separated based on a multi-cloud, as shown in FIG. 4E . When the user selects the MC-LB function as an option when deploying MCIS through the MCIS creation function of the system 1 according to an embodiment of the present invention and selects the virtual machines 400 to which load balancing is to be applied, MCIS deployment proceeds A virtual machine 400 for a load balancer is added and placed, and the load is distributed for the virtual machines 400 selected by the user as a load division target. When the virtual machine 400 is added to the MCIS as shown in Fig. 4f, if the MC-LB function is selected for the corresponding MCIS, the added new virtual machine 400 is added to the load balancing target virtual machine 400 by adding 5 MC - The load is also distributed to the newly added virtual machine 400 through the LB function.

When receiving a state condition for automatically controlling the quality of the MCIS from the user terminal 100 , the automatic controller 390 automatically performs at least one preset action when the state condition is satisfied or unsatisfied.

The automatic control unit 390 manages the MCIS automatic control requirements input from the user terminal 100 in the form of a single policy, refers the scheduler for automatic control to start automatic control, and the current state of MCIS is It continuously checks whether or not it meets the state condition requested by the user terminal 100 through monitoring information, performs triggering for automatic control when checking whether it meets, and when the automatic control is triggered, the user terminal 100 ) can perform at least one action requested.

This is a function to automatically control the quality of MCIS according to the rules specified by the user. The user suggests a state condition for automatically controlling the MCIS, and when the corresponding state condition is satisfied or unsatisfied, a specific action can be presented to be automatically performed. The MCIS automatic controller provides a mechanism to perform various conditions and actions included in the user's rules. Detailed functions are classified as follows.

1) Management of MCIS automatic control requirements

This is a function that supports the registration, inquiry, and deletion of 5 MCIS automatic control requirements requested by the user. MCIS automatic control requirements are managed in the form of one policy, and the scheduler for automatic control refers to this and initiates automatic control.

2) Determination of MCIS control conditions

It continuously checks whether the current state of the MCIS meets the state condition requested by the user through monitoring information, and triggers for automatic control when the conformance is checked. Examples of monitoring information include resource utilization, performance measurement, and lifecycle status.

3) Execute MCIS control action

Provides the function to perform the action requested by the user when automatic control is triggered. In this case, the type of action performed is expandable.
