[0001] APPARATUS AND METHOD FOR PROVIDING CLOUD INFRASTRUCTURE SHARING [0002]

The present invention relates to a cloud infrastructure sharing apparatus and method thereof, and includes a system structure for sharing infrastructure information between clouds, a method for moving information between an information management method and an infrastructure sharing cloud.

The present invention relates to a cloud computing system, and more particularly, to a system and method for supporting infrastructure sharing among clouds.

Typically, the cloud infrastructure is used to collectively refer to computing resources, including CPU, memory, storage, and network resources, of servers residing in the cloud.

Also, generally, the cloud service is provided through a single cloud, and the cloud service is dependent on the specific cloud. In addition, the performance of the cloud service is directly affected by the system resource state, network bandwidth, and other conditions of the cloud in question. Also, in general, individual cloud service providers have limitations of continuous infrastructure expansion for resources required by a rise in service workload occurring at a specific point in time.

However, through the cloud infrastructure sharing system and its method, it can maintain the stable performance of the cloud service by allowing the provision of the service utilizing other cloud resources in case of limitation of the system resources and network bandwidth of the single cloud, or anticipated power failure and maintenance of the cloud And shortening the service interruption time. In other words, researches to utilize multiple clouds to overcome limitations of single cloud are continuing.

In particular, the technology described in U.S. Patent No. 653,701 discloses a method for a cloud client using a cloud service (Web Service, SaaS, PaaS, IaaS) to find and connect to another cloud service existing in an external network, To explore ways to leverage multiple clouds.

In addition, the contents of US Patent (651,482) disclose that monitoring tools for existing services are only considered for monitoring services in a limited area (e.g., a single cloud), but more and more services are deployed on multiple clouds And a structure and method for monitoring services existing on multiple clouds are disclosed.

However, the above-mentioned technologies have a problem in that the resource information on the cloud is continuously updated to share the latest information and the service can not be efficiently moved.

The present invention relates to a cloud infrastructure sharing system and method, and a system structure and an information management method for sharing infrastructure information between clouds. Another object of the present invention is to provide a method of moving a service in a cloud infrastructure shared environment.

In order to achieve the object of the present invention, an infrastructure sharing support apparatus according to an exemplary embodiment of the present invention collects server resource information transmitted from an information collection agent provided in each server included in the cloud and stores cloud resource information of the cloud A cloud infrastructure information manager that receives and stores cloud infrastructure integration information including cloud resource information of each of a plurality of clouds, and generates and manages cloud resource information of the plurality of clouds by collecting cloud resource information of each of the plurality of clouds And transmits the cloud infrastructure integration information to the cloud infrastructure integration information manager for generating and managing the cloud infrastructure integration information. The cloud infrastructure integration information manager receives the cloud infrastructure integration information and transmits the cloud infrastructure integration information to the cloud infrastructure information manager, When a service movement request signal is received from a server and a server included in the cloud, information of a service movement target cloud suitable for movement of the service is retrieved through the cloud infrastructure information manager, And a service movement relay module for transferring data required for movement of the service to perform service movement.

According to another aspect of the present invention, there is provided an infrastructure sharing support method, comprising: receiving cloud resource information from an information collection agent provided in each server included in a cloud in a cloud infrastructure information manager; Generating cloud resource information of the cloud by collecting server resource information of the cloud; and transmitting the generated cloud resource information to the cloud infrastructure integrated information manager to generate cloud infrastructure integration information, The method comprising the steps of: receiving and storing the cloud infrastructure integration information through the cloud infrastructure sharing interface; and receiving, through the stored cloud infrastructure integration information, Searching the information of the service movement target cloud suitable for movement of the service being provided, allocating resources in the searched service movement cloud, and transmitting data necessary for movement of the service to perform movement of the service.

According to the cloud infrastructure sharing system and method of the present invention, since an extra infrastructure can be shared among a plurality of clouds, it is possible to cope with the problem of a single cloud, and it is possible to efficiently utilize infrastructure resources not used for each cloud, It is possible to increase the value of the infrastructure.

Further, according to the cloud infrastructure sharing system and method of the present invention, it is possible to share an extra infrastructure among a plurality of clouds, so that when there is a shortage of resources due to an unpredictable increase in service requests, Such as a service interruption caused by a power failure or the like, can be coped with.

In addition, it can increase the value of the cloud infrastructure by enabling efficient utilization of infrastructure resources that are not used in each cloud.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

The cloud infrastructure sharing system and method according to the present invention includes a system structure, an information management method, and a service moving method in a cloud infrastructure sharing environment for sharing infrastructure information between clouds. Usually, a physical system in the cloud is an environment in which a plurality of virtual machines are running, and each service can be executed in a virtual machine.

In order to share the cloud infrastructure, the information of the infrastructure of the individual cloud should be mutually shared, and the available infrastructure resources of the shared cloud should be managed as one resource pool concept. Thus, each cloud participating in infrastructure sharing can know all the information about the currently shared infrastructure, and can acquire and utilize the optimal infrastructure resource information (access method, resource characteristics, etc.) at the time of using the shared infrastructure. In addition, using shared infrastructure means that the service is performed using the corresponding infrastructure by moving the service to the target cloud.

In other words, cloud infrastructure sharing is an extension of the service's available cloud infrastructures, and infrastructure supports the movement of services between shared clouds. Cloud infrastructure sharing can share the entire infrastructure of the cloud or some of the infrastructure, and can optionally specify the scope of the share.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

1 is a diagram illustrating a configuration of a cloud system capable of infrastructure sharing according to an embodiment of the present invention.

1, the cloud infrastructure sharing support apparatuses 110 and 110a include a cloud infrastructure information manager 112 that periodically collects and manages resource information of the individual clouds 130 and 130a, And a service movement relay module 113 that provides movement of the inter-service, collects server resource information transmitted from the information collection agent 121 provided in each server included in the cloud, Generates and manages resource information, and receives and stores cloud infrastructure integration information including cloud resource information of each of a plurality of clouds.

Here's how to share infrastructure information among the participating cloud-sharing infrastructure.

First, the information collecting agent 121 existing in each server system 120 for infrastructure sharing in the cloud periodically collects resource information (CPU, memory, storage capacity, network usage amount, etc.) of the corresponding server system . The cloud infrastructure information manager 112 collects / manages the entire resource information of the corresponding cloud, and periodically acquires resource information 122 from the information collection agent 121 of the server system as an object of infrastructure sharing. The information of the acquired individual server system is used to generate the entire resource information of the corresponding cloud, and the entire resource information is periodically updated to maintain the accuracy of the available resource state.

In addition, the cloud infrastructure information manager registers and deletes servers for infrastructure sharing, thereby enabling selective sharing of servers in the cloud.

The cloud infrastructure sharing interface 111 may provide interfaces 140, 140a, and 141 for communication and data transmission with the cloud-to-cloud or cloud-infrastructure integrated information manager 100 participating in infrastructure sharing.

That is, the cloud infrastructure sharing interface 111 includes a cloud infrastructure integrated information manager 111 for collecting cloud resource information generated by the cloud infrastructure information manager and cloud resource information of each of the plurality of clouds, and generating and managing the cloud infrastructure integrated information, (100), and receives the cloud infrastructure integration information from the cloud infrastructure integration information manager and transmits the integrated cloud infrastructure integration information to the cloud infrastructure information manager.

The cloud infrastructure integrated information manager 100 collects and manages resource information of all the clouds participating in the cloud infrastructure sharing. Therefore, the resource information of the individual cloud is periodically collected (140, 140a) from the cloud infrastructure information manager 112 of each cloud to generate and update the resource information of the entire infrastructure shared cloud.

In addition, the shared infrastructure information of the entire generated cloud is periodically re-transmitted to the cloud infrastructure information manager existing in each cloud, so that each cloud holds the infrastructure information of the entire available cloud. Also, the transmission of the shared infrastructure information of the entire cloud is continuously repeated with a certain period, so that the cloud infrastructure integrated information manager and each cloud can always keep the latest shared infrastructure information.

2 is a diagram illustrating resource information collection of a cloud system according to an embodiment of the present invention.

According to the embodiment, each of the clouds 130, 130a, and 130b among the clouds participating in sharing the infrastructure shares the infrastructure information 114, 114a, and 114b of the individual cloud, The unified infrastructure information 115 of shared clouds can be secured. Thus, each cloud can know the amount and status of available resources and this information can be updated periodically.

3 is a diagram illustrating a configuration of a service movable cloud system according to an embodiment of the present invention.

According to an embodiment, when the service movement relay module 113 receives a service movement request signal from any server included in the cloud, the service movement relay module 113 transmits information of the service movement target cloud suitable for movement of the service through the cloud infrastructure information manager And the service movement can be performed by allocating resources in the searched cloud to be moved and transmitting data necessary for movement of the service.

In addition, virtual machines 123 and 123a in which services are running may exist in each of the server systems 120 and 120a on the clouds 130 and 130a. The virtual machine is connected to a storage 150 and 150a for storing image and service data of a virtual machine and the storage is connected to the service movement relay modules 113 and 113a of the cloud infrastructure sharing support devices 110 and 110a in each cloud ).

Accordingly, the service movement relay module 113 has a data receiving unit for receiving the virtual machine image and data from the server system of the corresponding cloud, and a data transmission unit for transmitting the data to the service moving relay module 113a on the target cloud to be moved .

In addition, the server systems to be shared by the cloud infrastructure are aware of the information of the cloud infrastructure sharing system of the belonging cloud, and can request the service sharing request to the cloud infrastructure sharing system when requesting the service migration.

That is, when the service movement relay module 113 receives the service movement request signal from any server included in the cloud, the service movement relay module 113 searches the information of the service movement target cloud suitable for the movement of the service through the cloud infrastructure information manager , And can allocate resources in the searched cloud to be moved and transmit data necessary for movement of the service to perform service movement.

In addition, when requesting movement of a service, each server system transmits resource information required for service movement, and other additional costs, security, cloud SLA, urgency, etc. may be transmitted together.

In addition, the cloud infrastructure information manager 112, upon receiving the search request signal of the service movement target cloud from the service movement relay module 113, searches the cloud infrastructure information management server 112 based on the stored cloud infrastructure integration information, And transmit the determined cloud address information of the cloud to the service movement relay module.

Next, the cloud infrastructure integrated information manager 100 collects resource information from the infrastructure information manager 112 of each cloud, and the collected data is collected by the cloud infrastructure integrated information manager to generate cloud infrastructure integrated information (S403) .

In addition, according to the embodiment, the cloud infrastructure information manager generates an infrastructure shared server list, registers and deletes the servers included in the infrastructure shared server list, and manages only the servers included in the infrastructure shared server list, And receive the resource information.

Next, the generated cloud infrastructure integrated information is retransmitted to the cloud infrastructure information manager of each cloud (S404).

According to the embodiment, the generated cloud infrastructure integrated information is periodically re-transmitted to the cloud infrastructure information manager existing in each cloud, so that each cloud holds the infrastructure information of the entire cloud available. Also, the transmission of the shared infrastructure information of the entire cloud is continuously repeated with a certain period, so that the cloud infrastructure integrated information manager and each cloud can always keep the latest shared infrastructure information.

Also, it is possible to search information of a service movement target cloud suitable for movement of a service being performed by an arbitrary server included in the cloud through the stored cloud infrastructure integration information, allocate resources from the searched service movement target cloud, The service can be moved by transmitting data necessary for movement of the service (S405).
