Description

SYSTEM AND METHOD FOR CREATING STACK OF VIRTUAL MACHINE [0002]

Embodiments of the present invention relate to a virtual machine stack creation system and method, and more particularly to a technique for efficiently creating a virtual machine stack in a cloud service.

A virtual machine is software that acts as an interface between a specific code (for example, Java binary code) and a microprocessor that executes actual program instructions. In order to provide a virtual machine, a virtual machine image is required. In order to satisfy various users' needs, various virtual machine images corresponding to each requirement are required. In order to create and modify storage and each image, time and cost efforts are required.

To improve this, an automatic configuration method for recording software package information required by a service manager and various environment settings in a predetermined format is used. The service manager creates a virtual machine using the basic virtual machine image, and installs necessary service modules or completes various environment settings using pre-stored automatic configuration information. This reduces storage wastage and reduces the effort required to create and modify virtual machine images. However, in this case, it is still necessary to generate and manage automatic configuration information according to the configuration of each virtual machine environment. In particular, much effort is required to provide an environment of a virtual machine stack having an N-tier structure in accordance with a user's demand. This is because it is necessary to create and manage image sets or script sets that meet the requirements of each user.

1 is a block diagram showing a detailed configuration of a virtual machine stack creation system 100 according to an embodiment of the present invention. The virtual machine stack creation system 100 according to an exemplary embodiment of the present invention is a system for creating a virtual machine stack that provides a specific service to a user terminal 150. [ The user terminal 150 may be a desktop computer, a notebook computer, a smart phone, a tablet computer, or the like, for receiving a specific service through a virtual machine stack. Here, the virtual machine stack refers to a set of a plurality of virtual machines stacked in a specific hierarchical structure and linked to each other so that a specific service can be provided to the user terminal 150. The virtual machine stack can be of an N-tier architecture. At this time, each layer may include one or more service modules. The service module refers to an application, a middleware, a software package, or a set thereof providing a specific service, for example, a web server, a web application server, a database, a proxy server, a compiler, an IDE, and the like. The virtual machine stack can have, for example, a three-tier structure of a web server, a web application server, and a database. In the virtual machine stack, a web server, a web application, One, three, or two, respectively. Hereinafter, a detailed configuration of the virtual machine stack creation system 100 will be described with reference to FIG.

1, the virtual machine stack creation system 100 includes a virtual machine creation unit 102, a script identification unit 104, a script storage unit 106, an internal storage unit 108, an external storage unit 110 and a virtual machine 112. Here, each configuration of the virtual machine stack creation system 100 may be located inside a cloud service system (not shown). A part of the configuration of the virtual machine stack creation system 100, for example, the script identification unit 104, the script storage unit 106, the external storage unit 110, and the like may be provided outside the cloud service system It may be located.

The virtual machine generation unit 102 receives virtual machine stack information having an N-tier structure from the user terminal 150 and generates a plurality of virtual machine stack information (for example, M, M > N) virtual machine. The virtual machine stack information may include at least one of a type of service module to be installed to provide a specific service to the user terminal 150, a number of service modules, a clustering method between service modules, and a replication method between service modules . For example, the virtual machine stack information includes information about a three-tier virtual machine stack environment consisting of one NginX web server, three Tomcat web application servers (WAS), two MySQL databases (DB) Information about the stack environment in which the Tomcat web application server is clustered, and information about the stack environment in which two MySQL databases are replicated to each other.

The virtual machine generation unit 102 may generate a plurality of virtual machines 112 according to the virtual machine stack information received from the user terminal 150. [ For example, if the virtual machine stack information includes information about a three-tier virtual machine stack environment composed of one NginX web server, three Tomcat web application servers, and two MySQL databases, It is possible to collectively create six virtual machines 112. The virtual machine creation unit 102 can create the virtual machine 112 using the virtual machine image. Then, the virtual machine generation unit 102 can allocate a cloud resource such as a CPU, a memory, and a network to the generated virtual machine 112. [

In addition, the virtual machine generation unit 102 transmits the virtual machine stack information to the script identification unit 104. The virtual machine generation unit 102 may generate a plurality of virtual machines 112 and then transmit the virtual machine stack information to the script identification unit 104. However, the present invention is not limited thereto. The virtual machine generation unit 102 may transmit the virtual machine stack information to the script identification unit 104 in the process of generating the plurality of virtual machines 112 and may transmit the virtual machine stack information to the script identification unit 104 A plurality of virtual machines 112 may be created. The script identification unit 104 may request the script storage unit 106 for one or more specific scripts corresponding to the virtual machine stack information. The script identification unit 104 may receive the script from the script storage unit 106 and then transmit the script to the virtual machine generation unit 102. [

The virtual machine generation unit 102 generates a minimum-virtual machine stack using the script received from the script identification unit 104. [ Here, the minimum-virtual machine stack refers to the environment of the virtual machine stack that satisfies the N-tier structure and is composed of the minimum number (N) of virtual machines 112. For example, if the virtual machine stack to be eventually created consists of one NginX web server, three Tomcat web application servers, and two MySQL databases, then the minimum - virtual machine stack is one NginX web server, one Tomcat web application server 1 , And a single MySQL database. That is, the minimum-virtual machine stack is configured to include N virtual machines 112 in which different service modules are installed. The specific process by which the virtual machine generation unit 102 generates the minimum-virtual machine stack will be described later with reference to FIG.

The virtual machine generation unit 102 completes the virtual machine stack based on the script received from the script identification unit 104 and the minimum-virtual machine stack. The virtual machine generation unit 102 does not sequentially install and configure the service modules in each of the M virtual machines 112 (M? N) ), The service module is installed and configured to configure the minimum-virtual machine stack, and then the remaining structure of the virtual machine stack can be completed by using this. A concrete procedure of the virtual machine generation unit 102 to complete the virtual machine stack will be described later with reference to FIG.

The script identification unit 104 receives the virtual machine stack information from the virtual machine generation unit 102, receives one or more scripts corresponding to the virtual machine stack information from the script storage unit 106, . Here, the script includes an installation script for installing the service module included in the virtual machine stack information, an update script for setting the environment of the service module, a clustering script for clustering the service module, Lt; RTI ID = 0.0 > and / or < / RTI > The environment setting of the service module is used in a broad sense including, for example, setting the operation of the service module, setting the host name, setting the connection relation between the service modules, setting the communication state, and setting whether to allow connection to the SSH . Each script may be stored in the script storage unit 106 in a form executable in the virtual machine 112. Each script may be a set of instructions for requesting the internal storage unit 108 or the external storage unit 110 for an installation file, an update file, a clustering file, or a replication file of the corresponding service module. When the script is executed in the virtual machine 112, the virtual machine 112 stores an installation file, an update file, a clustering file, a replication file, and the like for the service module in the internal storage unit 108 or the external storage unit 110 After receiving the request, it can perform installation, update, clustering, and replication operations for the service module.

The script storage unit 106 is a place where scripts for a predetermined service module are stored, and the scripts for the service module may be modularized and stored. For example, the script related to the Tomcat web application server is divided into an installation script of the Tomcat web application server, an update script of the Tomcat web application server, a clustering script of the Tomcat web application server, etc. and stored in the script storage unit 106 . The script storage unit 106 may transmit the script to the script identification unit 104 in response to a script request of the script identification unit 104. [

The internal storage unit 108 stores a setup file, an update file, a clustering file, a replication file, and the like for a predetermined script. As described above, when a script for a specific service module is executed in the virtual machine 112, the virtual machine 112 stores the installation file, the update file, the clustering file, the replication File, and so on. Accordingly, the internal storage unit 108 can transmit the file to the virtual machine 112. [ For example, when the installation script of the Tomcat web application server is executed in the virtual machine 112, the virtual machine 112 requests the installation file of the Tomcat web application server to the internal storage 108, You can install a web application server. The internal storage 108 may reside within a cloud service system (not shown).

The external storage unit 110 stores the installation file, the update file, the clustering file, the application file, and the like of the predetermined script. The external storage unit 110 performs the same function as the internal storage unit 108. However, the external storage unit 110 may exist outside the cloud service system. As described above, each script may be composed of a set of instructions for requesting the internal storage unit 108 or the external storage unit 110 for an installation file, an update file, a clustering file, or an application file of the corresponding service module, The machine 112 may request a file for the service module in the internal storage 108 or the external storage 110 according to the script.

The virtual machine 112 is a software module that is provided to the user terminal 150 and can be generated by the virtual machine creation unit 102. The scripts for the particular service module described above may be executed within the virtual machine 112. [ The virtual machine 112 requests an installation file, an update file, a clustering file, a replication file, and the like of the service module to the internal storage unit 108 or the external storage unit 110 according to the execution of the script, Update, clustering, replication, and so on.

Next, the virtual machine generation unit 102 can transmit the virtual machine stack information to the script identification unit 104. [ The script identifying unit 104 may request one or more scripts corresponding to the virtual machine stack information to the script storage unit 106 and then receive the script from the script storage unit 106. [ Specifically, the script identification unit 104 includes an NginX web server installation script, a Tomcat web application server installation script, a MySQL database installation script, an NginX web server update script, a Tomcat web application server update script, A script, a clustering script of the Tomcat web application server, and a replication script of the MySQL database to the script storage unit 106, and then receive these scripts from the script storage unit 106.

Next, the virtual machine generation unit 102 can generate the minimum-virtual machine stack 200 including the three virtual machines 112-1, 112-2, and 112-5 using the received script . To this end, the virtual machine creation unit 102 first executes the installation script and the update script for the different service modules in each of the three virtual machines 112-1, 112-2, and 112-5. Specifically, the virtual machine generation unit 102 executes the installation script of the NginX Web server and the update script of the NginX Web server in the first virtual machine 112-1, The installation script of the application server and the update script of the Tomcat web application server can be executed, and the installation script of the MySQL database and the update script of the MySQL database can be executed in the fifth virtual machine 112-5.

The first virtual machine 112-1, the second virtual machine 112-2 and the fifth virtual machine 112-5 store the service modules received from the internal storage 108 or the external storage 110 The service module can be installed and updated by using the file and the update file. As the update script of the service module is executed, the connection relationship between each service module can be defined. For example, the NginX web server and the Tomcat web application server can be connected, and the Tomcat web application server and the MySQL database can be interconnected.

Referring to FIG. 2 (b), through the above process, three virtual machines 112-1, 112-2, A minimum-virtual machine stack including the virtual machine 112-5 is created. Meanwhile, the virtual machine generation unit 102 collectively generates six virtual machines 112-1, 112-2, 112-3, 112-4, 112-5, and 112-6, and then performs the above- Virtual machine stack 200 can be created through three virtual machines of the six virtual machines 112-1, 112-2, 112-3, 112-4, 112-5, and 112-6 Virtual machine stack 200 is generated as soon as the virtual machines 112-1, 112-2, and 112-5 are generated, and the generated three virtual machines 112-1, 112-2, and 112-5 are Virtual machine stack 200, which includes the < RTI ID = 0.0 >

3 is a diagram illustrating a process of the virtual machine generation unit 102 completing the virtual machine stack 300 based on the minimum-virtual machine stack 200 according to an embodiment of the present invention. FIG. 3A is a diagram illustrating a process of installing and updating a specific service module in the third virtual machine 112-3, the fourth virtual machine 112-4, and the sixth virtual machine 112-6 3B shows a service module installed in the third virtual machine 112-3, the fourth virtual machine 112-4 and the sixth virtual machine 112-6 in the minimum-virtual machine stack 200, FIG. 2 is a diagram illustrating a process of clustering or replication with a service module installed in a network. 3 (c) is a diagram showing a state in which the virtual machine stack 300 is completed.

3 (a), the virtual machine creation unit 102 creates a virtual machine 100 in which the virtual machines 112-1, 112-2, and 112-5 included in the minimum- (112-3, 112-4, and 112-6) executes the installation script and the update script for the specific service module. Specifically, the virtual machine creation unit 102 executes the installation script of the Tomcat web application server and the update script of the Tomcat web application server in the third virtual machine 112-3 and the fourth virtual machine 112-4, respectively , The installation script of the MySQL database and the update script of the MySQL database can be executed in the sixth virtual machine 112-6. Accordingly, the third virtual machine 112-3 and the fourth virtual machine 112-4 can access the internal storage 108 or the external storage 110 with the installation file of the Tomcat web application server and the installation file of the Tomcat web application server The sixth virtual machine 112-6 requests the update file of the MySQL database and the update file of the MySQL database to the internal storage unit 108 or the external storage unit 110 and receives the update file .

Referring to FIG. 3B, the virtual machine creation unit 102 creates a virtual machine 112-1, 112-2, 112-3, 112-4, 112-5, and 112-6, Some can be clustering or replication. In general, clustering is a process of bundling data into one or more sets based on concepts such as similarity. In this case, it means that service modules providing the same service are bundled into one set. Replication generally refers to copying (or copying) data from a host computer to another computer. In this case, it means sharing specific information (or copying specific information) between service modules having the same function. The virtual machine creation unit 102 creates a Tomcat web application server installed in the third virtual machine 106-3 and the fourth virtual machine 106-4 and a Tomcat web application server installed in the second virtual machine 106-2 And DB replication between the MySQL database installed in the sixth virtual machine 106-6 and the MySQL database installed in the fifth virtual machine 106-5 can be performed.

According to embodiments of the present invention, it is possible to create environments of various virtual machine stacks that meet the needs of users by reusing the scripts used in the minimum-virtual machine stack 200. [ In particular, the script of the service module is modularized by tasks such as installation, update, clustering, and replication, and can be easily managed by combining or reusing them. As a result, the cloud service provider can efficiently satisfy the user's demand with less effort.

4 is a diagram for explaining an effect of efficiently managing scripts related to environment setting of a service module when the virtual machine stack creation system 100 according to an embodiment of the present invention is applied, .

FIG. 4A is a diagram illustrating a method of managing scripts related to environment setting of a service module according to the related art, and FIG. 4B is a diagram illustrating a configuration of a service module according to an embodiment of the present invention. And shows a method of managing a script.

4A, conventionally, after a virtual machine is created, necessary service modules are installed using some of the pre-stored automatic environment configuration scripts (# 1 to #N) Respectively. However, according to the related art, various automatic environment configuration scripts have to be configured to satisfy various users' needs, and it has been troublesome to individually verify and manage these automatic environment configuration scripts.

However, as can be seen in Figure 4 (b), according to embodiments of the present invention, a minimum set of scripts (package (or service module) # 1 install script, package # A plurality of virtual machine stacks can be created by combining and reusing them after configuring one or more update scripts, package # 2 install scripts, package # 2 update scripts, package # 3 install scripts, package # 3 update scripts, and the like. If a new service module is added, a new virtual machine stack environment can be easily configured in the same manner by adding only an install script and an update script for the service module. In addition, according to embodiments of the present invention, it is possible to reduce the time and cost wasted by the script verification and to reduce the burden on the virtual machine stack management by combining or reusing the used (verified) scripts.

FIG. 5 is a diagram for explaining an effect of efficiently creating a virtual machine stack when a virtual machine stack creation system 100 according to an embodiment of the present invention is applied, compared with the prior art. FIG. 5A is a diagram illustrating a method for creating a virtual machine stack according to the related art, and FIG. 5B is a diagram illustrating a method for creating a virtual machine stack according to an embodiment of the present invention.

In general, the time it takes to provide the virtual machine stack environment is the time it takes to complete the configuration of all virtual machines. Here, it takes a lot of time to create the virtual machine and install the service module, and the time required for setting the environment is relatively small.

Referring to FIG. 5A, conventionally, a virtual machine is created and a cloud resource is allocated to the virtual machine, and then a service module is installed and an environment is set. In addition, when a new service module is to be added, a new virtual machine is created, cloud resources are allocated to the virtual machine, the service module is installed, and the environment is set. That is, conventionally, a series of processes for creating a virtual machine stack are sequentially performed regardless of the structure of the virtual machine stack, the type and number of service modules, and the like. According to the related art, it is troublesome to individually verify and manage a series of processes leading to creation of a virtual machine stack.

However, as shown in FIG. 5B, according to the embodiments of the present invention, the process for creating the minimum-virtual machine stack among the series of processes leading to the creation of the virtual machine stack is performed first , You can install additional services modules and set up your environment by reusing or combining scripts (ie, verified scripts) used in the min-virtual machine stack creation process. Accordingly, it is possible to prevent the cumbersome process of verifying and managing a series of processes leading to the creation of the virtual machine stack. Also, in this process, it is possible to complete the creation of the virtual machine that takes the most time and the installation of the service module as soon as possible, and then to adjust the order of the operations that finish quickly, thereby providing the environment of the virtual machine stack more quickly. Furthermore, since all scripts are modular in their operations and stages, it is very easy to add new service modules. That is, a new service module can be easily added by executing a script to be added to the virtual machine.

First, the virtual machine generation unit 102 receives virtual machine stack information having an N-tier structure from the user terminal 150 (S602). As described above, the virtual machine stack information includes a type of service module to be installed in order to provide a specific service to the user terminal 150, a number of service modules, a clustering method between corresponding service modules, ≪ / RTI >

Next, the virtual machine creation unit 102 creates a plurality of virtual machines according to the virtual machine stack information (S604). The virtual machine creation unit 102 can create M (M? N) virtual machines using the virtual machine image.

Next, the virtual machine creation unit 102 creates a minimum-virtual machine stack (S606). More specifically, the virtual machine generation unit 102 transmits the virtual machine stack information to the script identification unit 104, and the script identification unit 104 receives one or more scripts corresponding to the virtual machine stack information from the script storage unit 106 And transmits it to the virtual machine generation unit 102. Here, the script includes an installation script for installing the service module included in the virtual machine stack information, an update script for environment setting of the service module, a clustering script for clustering the service module, And may include one or more of the replication scripts. The virtual machine creation unit 102 can execute the installation script and the update script for different service modules in each of the N virtual machines to create a minimum-virtual machine stack.

Next, the virtual machine creating unit 102 creates a virtual machine in the virtual machine, excluding the N virtual machines, based on the script received from the script identifying unit 104 and the minimum-virtual machine stack, The install script and the update script for some of them (S608). In addition, when the virtual machine stack information includes information on clustering or replication for a specific service module, the virtual machine generating unit 102 may execute a clustering script or a replication script for the service module.

Next, the virtual machine creation unit 102 determines whether or not the remaining virtual machine exists (S610). If the remaining virtual machine does not exist, the virtual machine creation unit 102 completes configuration of the entire virtual machine stack and interface setting work (S612 ). If there is a remaining virtual machine in step S610, the process returns to step S608 to execute the installation script and the update script for the remaining virtual machine.
