1 shows a structure of a cloud data center management system to which the present invention can be applied. Although only two data centers 1200 are shown in FIG. 1 for convenience of explanation, it is apparent to those skilled in the art that a greater number of data centers may be located and that the present invention is not limited to any particular number of data centers .

As shown, the cloud data center management system 1000 is provided in each of a plurality of cloud data centers 1200 located in a plurality of regions, and is provided with a local management apparatus Management apparatus' 1210), and a global management apparatus 1100 for managing the cloud data centers 1200 in an integrated manner.

The global management device 1100 can control and manage locally distributed cloud data centers 1200 via a network such as the Internet or a dedicated network and perform network topology management and resource allocation among them. The global management device 1100 operates in conjunction with the local management device 1210 installed in the data centers 1200. The global management apparatus 1100 does not directly manage or control the individual resources belonging to each data center 1200 and requests the abstraction or the abbreviated information and the profile defined by the resource container collectively, ) To request resource allocation.

In this structure, the user group A considers a plurality of locally distributed cloud data centers as a single logical cloud infrastructure, and receives cloud services. Accordingly, the user group A requests a desired service through the global management device 1100, and the global management device 1100 analyzes the service request of the user to select an optimal cloud data center or two or more cloud data centers, (E.g., Infrastructure-as-a-Service), and sends a control / management message to the local management device 1210 of the selected one or more cloud data centers for this purpose.

Alternatively, the user group B or the user group C may directly access the local management device 1210 of the cloud data center to receive services from a specific cloud data center among the cloud data centers that are distributed locally, And a service such as a virtual infrastructure may be directly provided. In some cases, all users may request service through the global management device 1100 and receive a service. As for the method of managing the cloud center distributed in this manner, reference is made to the description of the " Cloud Center Management Method and System "(Application No. 10-2013-0086295) already filed by the present applicant.

The cloud data center 1200 includes a variety of resources (e.g., computing H / W, network H / W, storage H / W) for cloud computing services. The local management device 1210 provided in each of these data centers can manage and monitor the resources in the data center and can create virtual resources based on the physical resources by using the virtualization function when necessary. In addition, the local management apparatus 1210 can transmit relevant information to the global management apparatus 1100 when a change occurs in the resource information due to the installation of a new resource, the addition or removal of a resource, or a failure in the data center.

2 is a block diagram illustrating a configuration of a virtual infrastructure service providing apparatus according to an embodiment of the present invention. The virtual infrastructure service provision apparatus 200 proposed by the present invention may be a subsystem of the global management apparatus 1100 of FIG.

In a distributed cloud infrastructure environment, a user may request a service provisioning and status control request (hereinafter referred to as a " virtual infrastructure service request ") including creation, modification, deletion, pause and restart of a virtual infrastructure And requests it via the global management device 1100. Here, the virtual infrastructure refers to the installation of networking services, volume storage devices, application software including one or more virtual machines, virtual networks, virtual routers, public IP addresses, firewalls, load balancing services, virtual private networks Setting, and the like. After authentication of the user and verification of whether or not there is an access right has been performed, the user's virtual infrastructure service request will be delivered to the virtual infrastructure service provision apparatus 200.

The virtual infrastructure service provision apparatus 200 determines that a virtual infrastructure can be optimally created and operated on one or more cloud data centers A to Z 1200 through analysis of a user's request for virtual infrastructure services, By sending the necessary control commands to the center (s), the requested virtual infrastructure is provisioned in one or more cloud data centers, and as each part of the virtual infrastructure created in the different cloud data centers is provisioned in one cloud data center, Accessibility and connectivity can be ensured. A detailed configuration of a virtual infrastructure service providing apparatus that provides such a function is shown in FIG.

2, the virtual infrastructure service provision apparatus 200 includes a service request verification unit 210, a resource size calculation unit 220, a data center selection unit 230, a network control unit 240, A service control unit 250, and a service control unit 260. [

The service request verification unit 210 receives a virtual infrastructure service request message (or a function, etc.) requested to the virtual infrastructure service providing apparatus 200 and verifies its validity. Here, the virtual infrastructure service request may include at least one of a service provisioning request (creation, change, deletion, etc.) and a status control (pause, restart, etc.) request.

In one embodiment, the service request verification unit 210 performs authentication for a user who has requested the service, and can verify whether the authenticated user has an appropriate authority required for the service request.

The resource size calculating unit 220 calculates a resource size required for satisfying a user's request for a virtual infrastructure service. In one embodiment, if a resource size specification required within a virtual infrastructure service request is explicitly defined (e.g., the number of virtual machines and the specification of the resources that make up each virtual machine (number of virtual CPUs, size of memory, The size of the disk, the number of the virtual network interfaces, and the like are explicitly defined), the resource size calculating unit 220 may calculate the size, quantity, and type of total resources required according to the defined specification.

On the other hand, when the size of the resources required for the virtual infrastructure service provisioning request is not explicitly defined (for example, a service provider who wants to provide a specific service by leasing a virtual infrastructure needs only the service information such as the size of the subscriber, And the specification of the virtual infrastructure is not specified), the resource size calculating unit 220 calculates the size and the size of the required resources (virtual machines, virtual network resources, virtual storage resources, etc.) based on the provided service information . Furthermore, the resource-size calculating unit 220 may configure the scale of the automatically calculated virtual infrastructure to scale-in / out dynamically according to the service load.

The data center selection unit 230 selects one or more optimal cloud data centers for creating the requested virtual infrastructure. The data center selection unit 230 will select the data center in consideration of the location, characteristics, and / or resource size of the virtual infrastructure service.

As an example, the data center selection unit 230 may select a data center considering the location of the requested virtual infrastructure service target persons. As another example, if the virtual infrastructure service request does not include location information to which the virtual infrastructure is to be provisioned, or if only wide-area location information is included, the data center selection unit 230 determines, based on the requested service characteristic, And select one or more optimal cloud data centers to provision.

In one embodiment, the data center selection unit 230 will select a cloud data center 1200 that has sufficient resources to accommodate the size of the virtual resources calculated through the resource size calculation unit 220. At this time, one cloud data center may be selected for the requested virtual infrastructure, or two or more different cloud data centers that are distributed locally may be selected.

The network control unit 240 may select the selected cloud data centers 1200 in the case where two or more cloud data centers 1200 are selected to create the virtual infrastructure requested by the data center selection unit 230 Interconnects over a network. In one embodiment, the network controller 240 may extend the virtual network through a virtual private network (VPN), a software-defined networking (SDN), or a dedicated line to allow the cloud data centers 1200 to be interconnected . That is, virtual machines created in arbitrary cloud data centers are included in the same virtual infrastructure but are physically located in other cloud data centers, and L2 or private L3 networks (access and connection via private IPs rather than public IPs) ). ≪ / RTI >

The virtual infrastructure configuration unit 250 generates local virtual infrastructure configuration information for the virtual infrastructure to be generated in the cloud data center and / or an interface message for transferring the configuration information, and transmits the configuration information to the local management apparatus of each cloud data center And transmits a local virtual infrastructure creation request message including information and / or interface messages.

Here, the local virtual infrastructure configuration information includes a resource control command (or message) for each of a plurality of resources required for the requested virtual infrastructure configuration. The virtual infrastructure configuration unit 250 generates an individual resource control command (for example, a virtual machine creation message, a virtual network creation message, a virtual storage creation message Etc.) and send them to the corresponding cloud data center so that the virtual infrastructure can be provisioned.

At this time, the interfaces of the local management devices of the cloud data centers constituting the virtual infrastructure may not be the same. To this end, the virtual infrastructure unit 250 may generate an interface message for communicating local virtual infrastructure information to the local management apparatus of each cloud data center.

As an example, when the cloud data center is configured as OpenStack including Heat (OpenStack integrated management program), the virtual infrastructure unit 250 automatically generates the OpenStack Heat Template file and provides the necessary virtual infrastructure provisioning through the Heat API And request it to an OpenStack-based cloud data center 1200.

As another example, when the cloud data center is configured as OpenStack that does not include Heat, the virtual infrastructure configuration unit 250 generates an interface message for the Nova API, the Neutron API, and the Cinder API necessary for creating the virtual infrastructure, Can be requested to the cloud data center 1200 by calling virtual infrastructure provisioning sequentially (control commands in mutually dependent relationship take into account this relationship).

As another example, if some of the cloud data centers are CloudStack or AWS-based cloud data centers, the virtual infrastructure configuration unit 250 generates CloudStack or AWS interface messages for provisioning the virtual infrastructure to the corresponding cloud data center 1200 ).

The service control unit 260 controls at least one of the resource size calculating unit 220, the data center selecting unit 230, the network controlling unit 240, and the virtual infrastructure configuring unit 250, Ensure optimal virtual infrastructure configuration.

In one embodiment, the service control unit 260 grasps the specification level of the virtual infrastructure service request, and according to the determined specification level, the resource size calculation unit 220, the data center selection unit 230, the network control unit 240, And at least one of the virtual infrastructure configuration units 250 can be selectively controlled. Herein, the request level indicates only the basic application service information to be provided through the virtual infrastructure, from when the user inputs / specifies the specifications of all the virtual infrastructures in detail, and the virtual infrastructure providing apparatus 200 automatically determines the specification of the virtual infrastructure To various request levels until requested to do so.

3 is a flowchart illustrating a method of providing a virtual infrastructure service according to an embodiment of the present invention.

In step S310, the validity of the virtual infrastructure service request message is verified. The virtual infrastructure service request is at least one of a request for service provisioning (creation, change, deletion, etc.) and a request for status control (pause, restart, and the like), and the request in the embodiment is a service provisioning request for virtual infrastructure service creation I suppose.

In one embodiment, validation of a virtual infrastructure service request may include authentication of a user requesting the service and verification of whether or not it is appropriate for the service request.

In step S320, it is determined whether or not the virtual infrastructure resource size is explicitly defined in the validated virtual infrastructure service request.

If the virtual infrastructure resource size is not explicitly defined in the virtual infrastructure service request, the specification and size of the resources required for the virtual infrastructure configuration are automatically calculated based on the requested virtual infrastructure service information (S330).

In step S340, based on the requested virtual infrastructure service information and / or the calculated resource scale information, one or more optimal cloud data centers for creating a virtual infrastructure are selected.

In step S350, local virtual infrastructure configuration information to be generated in each cloud data center and / or an interface message for communicating the generated virtual infrastructure configuration information are generated for each of the at least one cloud data center in which the virtual infrastructure is to be created, A local virtual infrastructure creation request message including the local virtual infrastructure configuration information is transmitted (S380).

It is determined that one virtual infrastructure is not created in two or more physically different cloud data centers (S360), that is, it is determined in step S340 whether two or more cloud data centers have been selected. In such a case, by creating a virtual network between the cloud data centers, the virtual network of the local virtual infrastructure can be interconnected and accessed (S370).
