Description

TECHNICAL FIELD [0001] The present invention relates to a virtual cluster system providing method and a virtual cluster system providing apparatus,

The present invention relates to a method for providing a virtual cluster system and an apparatus for providing a virtual cluster system, and more particularly, to a method and system for providing a virtual cluster system for implementing an optimized virtual cluster.

As the virtual computing system evolves, a demand for a virtual cluster system capable of performing virtual computing using one or more virtual machines is increasing.

In particular, software for analyzing large data, such as Hadoop, includes a plurality of computing machines to process data greater than the rate at which a single machine processes the data and greater than the amount that a single machine processes Cluster. ≪ / RTI > Each computing machine is assigned a distributed component of software. Accordingly, a plurality of computing devices can be configured to handle different allocation portions of one large file.

On the other hand, such software is composed of various components. For example, in case of Hadoop, JobTracker, TaskTracker, NameNode and DataNode of HDFS (Hadoop Distribute File System) can be configured.

The components may be configured to correspond to a physical computing device, with each computing device corresponding to a node of the cluster. However, when a node of a cluster is implemented in a physical computing device, it is difficult for an administrator to install and set up a distributed computing platform on each computer device.

Accordingly, there is an increasing tendency to use a virtual cluster system using a cloud system. A variety of services such as Infrastructure-as-a-Service (IAAS) and Platform-as-a-Service (PAAS) are being provided.

However, it has been difficult to suitably match the components of the platform to the infrastructure provided by using such services. Specifically, the distributed components of the software must meet different hardware specifications. However, in constructing the virtual cluster system, the user must know the hardware specification required by each component, and the user has difficulty in setting the hardware specification optimized for each component. For example, if the memory capacity of the node arbitrarily set by the user is not sufficient to execute the component installed in the node, the processing speed of the node may be significantly reduced.

Since the user does not know the hardware specification required for each component, he implemented the optimized cluster through trial and error. Alternatively, the user would have to spend additional costs using a higher specification infrastructure than the component needed.

3 is a flowchart illustrating a method of providing a virtual cluster system according to an embodiment of the present invention. 4A to 4F are views for explaining a method of providing a virtual cluster system according to an embodiment of the present invention.

First, in the virtual cluster system providing method, system information about a virtual cluster system including at least one virtual machine is received (S310). The system information includes various system information for setting up the virtual cluster system. For example, the system information may include infrastructure information and / or platform information.

The infrastructure information includes the hardware specification of the virtual machine to be used as the node and all other information related to the virtual machine. For example, infrastructure information includes, but is not limited to, the number of virtual machines, the number of CPUs, the number of cores, the number of cores, the number of NICs, the operating system, the network bandwidth, the MAC address, the IP address, the type of storage, The type of the device, setting information for other network devices, and the like. The setting information for the network device includes setting information for a network device supporting virtual machine communication such as blocking port information, open port information, port opening / closing time information, connection authentication key, and the like.

The platform information includes all information related to the platform to be set in the virtual cluster system. For example, the platform information includes platform types such as Esper CEP, Drools, Hadoop, Tomcat, Nginx and the like and configuration information therefor. The configuration information includes the types of components in the platform, the number of components, and the like. Here, the components gather together to form a platform and perform different functions. For example, a component may include a computing and processing component, a data processing component, a data management component, a component management component, a platform component, a platform management component, a platform middleware component, an interworking component between components,

Referring to Figures 4A-4B, a configuration interface for receiving system information in a method of providing a virtual cluster system is shown.

First, the setting interface shown in Figs. 4A to 4F will be described. The left side of the interface shows the phase of the setting interface. The upper right corner of the interface displays the currently logged in user and the logout button. At the center of the configuration interface, information about the configuration of the virtual cluster system is displayed, and the user is configured to select, input, or modify the item. The item selection and input / modification of the user is performed according to a step.

Although various inputs to the system information are shown and described herein as being entered step by step, it is not limited thereto. That is, the system information may be set according to the steps as disclosed herein, but all information may be entered at once. Further, the setting interfaces shown in Figs. 4A to 4F are illustrative and can be configured in various ways. For example, the configuration interface may be configured to show each step one screen at a time.

Referring to FIG. 4A, a setting interface for inputting infrastructure information among system information is shown. In step 1, the number of virtual machines is input. The number of virtual machines may be one or more without limitation. In FIG. 4A, three virtual machines are illustratively set. In step 2, the hardware specification for each virtual machine is selected according to the number of input virtual machines. The specifications of the provided hardware can be selected from the above-described infrastructure stability information. For example, the selectable hardware specification may be a V CPU (Virtual CPU), the size of the memory, and the size of the disk. Next, in step 3, the operating system of the virtual machine can be selected. The operating systems of the selectable virtual machines may be, for example, Debian, Ubuntu, CnetOS, fedora, and the like. Next, in step 4, the name of the infrastructure is set.

In FIG. 4B, a setting interface for inputting platform information among the system information is shown. In step 1, the platform type is selected. As described above, the platform type is not limited to a platform capable of distributed computing, and may include a web service platform and the like.

Next, in step 2, the distribution type of the platform is selected. The distribution type is information on how various components for configuring the selected platform are allocated to each of the virtual machines. For example, how distribution of Hadoop components, JobTracker, NameNode, TaskTracker, and DataNode, to virtual machines is provided as a distribution type. However, a distribution type including other components may be provided, without being limited thereto. In step 3, the name of the platform is set. Or the distribution type may not be selected. If the distribution type is not selected, the virtual cluster system providing method can automatically select the distribution type.

On the other hand, the distribution type of the platform may be provided based on the number of virtual machines obtained from the infrastructure information and the platform type obtained from the platform information. For example, if the number of virtual machines in the infrastructure information is four, and the selected platform type is Hadoop, then all possible combinations of four virtual machines and Hadoop components may be shown as distribution types.

Referring back to FIG. 3, virtual mapping information for mapping at least one virtual machine of the virtual cluster system and a component of the platform is generated based on system information (S320).

Referring to FIG. 4C, the mapping information generation mode is selected in step 1 of the setting interface. The mapping information generation mode includes a manual generation mode, a semi-automatic generation mode, and an automatic generation mode. The manual generation mode is a mode in which mapping information is generated by a user by directly assigning a component to each of virtual machines. The semi-automatic generation mode is a mode in which mapping information is generated by selecting one of preset mapping information. And automatically generates mapping information for virtual machines and components based on the infrastructure information and the platform information. 4C, the automatic generation mode is selected.

When the automatic generation mode is selected, the virtual mapping information is generated, and then the recommended mapping information is generated based on the virtual mapping information (S330). In FIG. 4C, a setting interface is shown while generating the recommendation mapping information after the virtual mapping information is generated.

The virtual mapping information may be generated by a predetermined method as information on which of the components of the platform are assigned to each of the selected number of virtual machines. For example, the predetermined method is to assign a NameNode to the first virtual machine, TaskTracker to the next virtual machine, DataNode to the next virtual machine, and DataNode and TaskTracker if each component can not be assigned to a separate virtual machine. To a single virtual machine. However, without being limited thereto, a predetermined method for generating virtual mapping information may be a method of generating virtual mapping information in consideration of hardware specifications of virtual machines.

The recommendation mapping information is related to the arrangement of the platform components according to the infrastructure information, and the recommendation mapping information and the virtual mapping information may be the same or different. The recommended mapping information is mapping information that considers the hardware specification required by each component. In other words, the virtual mapping information is matching information generated according to the hardware specification of the virtual machine selected by the user, without reflecting the hardware specification required for each component of the platform differently. On the other hand, the recommended mapping information is recommended mapping information for allowing each of the components of the platform to be placed in a virtual machine having an optimized specification based on the hardware specification of the virtual machine set by the user. Accordingly, the recommendation mapping information may include virtual machines having hardware specifications different from the hardware specification selected by the user.

For example, suppose the platform is an Esper CEP and one virtual machine is selected as 1 core 1 CPU, 1GB memory. The virtual mapping information is generated by mapping the Esper CEP component to the above one virtual machine. However, the recommended mapping information is generated by mapping to a virtual machine with 1 core 1 CPU 2 GB memory, since the Esper CEP component operates at a very low processing speed in 1 core 1 CPU 1 GB memory. The hardware specification of the components for generating the recommendation mapping information may be pre-stored information. For example, the required hardware specification may be a hardware specification as reported in the literature or as a heuristic, or it may be a hardware specification provided by the software vendor. Or the required hardware specification may be a hardware specification analyzed and accumulated based on CPU utilization memory utilization and data throughput in the cluster system management device. More specific embodiments in which the recommendation mapping information is generated will be described with reference to Figs. 5 and 6A to 6C.

Next, along with the recommended mapping information, virtual mapping information is provided so that it can be modified (S340). Referring to FIG. 4D, in the mapping information selection in step 2, the virtual mapping information MyHadoop Cluster is shown and the recommended mapping information, Recommended MyHadoop Cluster 1, is shown. Among the recommended mapping information, VM 1 is a virtual machine having two CPUs different from VM 1 of the virtual mapping information. For example, since the virtual machine of the node where NameNode and JobTracker are installed has to have at least two CPUs, the recommended matching information is generated by the changed hardware specification. Thus, the changed information may be identified more easily by adding an identifier as in FIG. 4D. Each mapping information may be shown in tabular form, with the virtual machine name, virtual hardware specification, and mapped software platform components shown. In addition, a plurality of recommended mapping information may be provided. Also shown is a modification button for modifying information for each virtual machine.

When the modify button is selected, a setting interface that allows the virtual hardware specification to be changed as shown in FIG. 4E may be provided. In FIG. 4E, a setting interface for changing only hardware specifications is provided, but a setting interface may be provided that can change the matching of each of the platform components and virtual machines in the cluster.

Next, the user decision mapping information is received, and at least one virtual machine of the virtual cluster system is instantiated based on the user decision mapping information (S350). When the matching information of the component and the virtual machine is determined based on the provided virtual mapping information and the recommended mapping information, the user decision mapping information is generated. That is, if matching information provided to the client of the user is determined and an OK button, for example, is selected on the setting interface, the matching information is determined and determined as the user decision mapping information. The virtual cluster system providing apparatus can instruct the virtual cluster system management apparatus to establish a cluster based on the user security mapping information, and instantiate virtual machines through the virtual cluster system management apparatus. Referring to FIG. 4F, a setting interface for confirming the status of the set virtual machines is shown.

Those skilled in the art will appreciate that in addition to the system information determined through the configuration interface, a variety of other information is required in deploying the virtual machines and building the cluster system according to the user decision mapping information. Accordingly, those skilled in the art will appreciate that suitable system information, for example information for inter-component communication, may be selected in accordance with the system information selected by the user to construct and utilize the cluster system.

The method of providing a virtual cluster system according to an embodiment of the present invention provides automated recommended matching information for allocating hardware specifications optimized for each component, thereby enabling a virtual cluster system to be optimized even for a less experienced user do.

Further, in the method of providing a virtual cluster system, the use time of the virtual cluster system can be additionally received. That is, the user can determine the use time of the virtual cluster to be established at the construction stage. In this case, the use time of the virtual cluster system is scheduled. For example, the virtual machines may be set such that other tasks on the host where they are hosted are not performed at the determined time. Also, before the usage time of the virtual cluster system is determined, a recommendation time for the usage time may be provided based on the usage schedule of the system in which the virtual cluster system is hosted. Since the virtual cluster is operated at a low load on the host, the operation efficiency of the virtual cluster can be greatly improved.

5 is a flowchart for explaining a step of generating exemplary recommendation mapping information in a method of providing a virtual cluster system according to an embodiment of the present invention. 6A to 6C are tables for explaining a step of generating exemplary recommendation mapping information in a method of providing a virtual cluster system according to an embodiment of the present invention.

First, the system information including the infrastructure information and the platform information for the virtual cluster system is received (S610). This step is substantially similar to step 310 of FIG. 3, and therefore, a description thereof will be omitted.

Next, all the distribution models that can be implemented based on the platform information are identified (S620). Referring to FIG. 6A, all possible deployment models of Hadoop are shown in the table. The distribution model includes all other distribution models that include a NameNode, a JobTracker, a TaskTracker, and a DataNode, and a DataNode below the table.

Next, based on the selected infrastructure information, a distribution model that can be mapped among the identified distribution models is determined (S630). For example, if the number of virtual machines among the infrastructure information is two, models that can be applied when the number of virtual machines is two among all the executable distribution models identified in FIG. 2 are identified. Referring to FIG. 6B, distribution models of components that can be implemented in two virtual machines are shown in the table.

Recommendation mapping information for each of the mapping models is generated (S640). The recommendation mapping information is generated according to the system requirements of the platform information, that is, the result of comparing the hardware specification of the component with the infrastructure information. In addition, the recommendation mapping information may be generated using a pre-stored look-up table including hardware specifications corresponding to distribution models of implementable components.

Referring to FIG. 6C, there is shown a pre-stored look-up table for use in the recommendation mapping information. In the table of FIG. 6C, hardware specifications required for distribution models of components that can be implemented in two virtual machines are displayed. In the method of providing a virtual cluster system according to an embodiment of the present invention, recommendation mapping information is generated by comparing hardware specifications required for distribution models with infrastructure information inputted by a user. Next, the recommendation mapping information is provided to the user (S650).

The step of generating the above-mentioned recommended mapping information is exemplary and is not intended to be limited thereto. The virtual cluster system providing method may generate recommendation mapping information by various methods based on the infrastructure information and the platform information. For example, after determining the best and the most efficient hardware specifications for the components of the platform, the hardware specification of the selected virtual machine is assigned to each of the hardware specifications to determine a suitable virtual machine for the corresponding component, After the determination, a recommendation matching method may be configured to reinforce the hardware specification of the next virtual machine when the hardware specification is insufficient.

Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
