Based web hosting system capable of establishing an environment-specific virtual machine environment and improving the efficiency of Klaus service or hosting management.

With the increase of supply and demand of mobile devices, the use and supply of the necessary application programs are also increasing. The supply of various applications has become important due to the increase in the supply and demand of smart phones, especially in mobile devices.

Generally, the supply of such applications is mainly performed by the existing terminal operators and communication carriers. However, with the advent of the App Store in recent years, the supply of applications has been open not only to some operators but also to many individual developers. As a result, individual operators and developers who do not own the infrastructure of application provisioning can supply high quality application and application services.

However, the existing App Store was generally responsible for charging for the purchase, sale, and purchase of applications, and for transferring and installing applications. Therefore, in order to supply application services that interoperate with application programs based on existing infrastructure such as servers, a separate infrastructure for providing application services should be constructed. The construction of a separate infrastructure is burdensome not only for individual operators and developers who want to provide application services but also for existing terminal operators and telecommunication carriers. To reduce this burden, it is necessary to provide a technology for providing application services based on existing infrastructure such as servers.

Cloud computing makes it easy for users to lease storage, network, platform, and computer resources using distributed processing and virtualization technologies, enabling users to work from anywhere with a device with Internet access and computing capabilities. The most common types of cloud services are Infrastructure as Service (IaaS), Platform as Service (PaaS), and Software as Service (SaaS).

The SaaS cloud is a service that provides applications. Cloud computing service providers provide software through the Internet. Users can easily access and utilize the software without any configuration or installation. The PaaS cloud is a service that provides the environment in which users can develop software, and the service provider supports the development platform required by the user. The IaaS cloud typically aims to provide a hardware-centric service, but it only gives users control over the operating system to the application domain, excluding the physical domain.

The IaaS cloud is a service that provides service infrastructure. It is a concept that makes server, storage, and network into a virtualized environment through the Internet to provide computing capability to users as needed. In addition to these representative service types, they are gradually becoming more and more subdivided according to the type of users and becoming a new kind of service. Therefore, it is necessary to construct and manage the environment for IaaS, which has IT infrastructure environment and management capability skills and can be easily accessed based on these technologies.

These cloud stacks provide a user interface (UI) environment for easy management of virtual machines, networks, and storage over the Web and can support a wide variety of hypervisors such as Xen, KVM, VMware, vSphere and XenServer. have.

The host device 200 can access the cloud service access area through private and public accesses and the private area can be accessed only from the management tool in order to provide an exclusive service with enhanced security function in a private band And the access to the Internet is possible because there is no restriction on the use of the service in the common area.

To this end, the host device 200 includes a cloud management manager 210 and a cloud service processor 220.

The cloud management manager 210 executes an administrator program by a management tool that performs a command or a response processing function for managing the cloud infrastructure and manages events or work events generated by the execution of the administrator program as log data in the cloud database 212).

The cloud service processor 220 is controlled by the cloud management manager 210 to be used as a distribution area of the cloud stack, connects hardware resources to the network for cloud services, distributes and arranges virtual machines according to the VM use application signal, It performs the operation of adding, deleting, changing or extending the virtualization node managed in the cloud stack.

The function server 300 sets the DNS using the Web domain name service (DNS) automatic setting function and the authorized IP automatic allocation function through the VM use application signal in cooperation with the host device 200. [ The function server 300 may be implemented in various forms such as a DNS server, a DHCP server, or a DNS / DHCP integration server.

Meanwhile, when the cloud-based web hosting system is applied to an actual network environment, the L3 switch 310 is located between the client terminal 110 and the cloud management manager 210, and the L2 switch 320 ).

The L3 switch 310 is a switch operating at Layer 3, and provides switching function between the same VLAN ports to provide routing between different VLAN ports.

The L2 switch 320 is a switch operating at the Layer 2, and functions as a hardware function to transfer data by viewing a MAC address. In general, L2 switch 320 operates in one VLAN and supports default routing.

In addition, the cloud-based web hosting system may further include an administrator terminal 330 that executes an administrator program by a management tool, a geographically dispersed data center 340, and the like.

2 is a block diagram illustrating the configuration of the host apparatus of FIG.

Referring to FIG. 2, the cloud management manager 210 includes a cloud management server 211 and a cloud database 212.

The cloud management server 211 reinterprets the command transmitted by the management tool as a command recognizable by the hypervisor and transmits the command to the corresponding hypervisor and re-interprets the response data of the hypervisor according to the response format requested by the management tool To the management tool.

The cloud database 212 stores log data, virtual machine related data, and entire resource related information of the cloud infrastructure managed by the management tool in cooperation with the cloud management server 211. The cloud database 212 can be a MySQL cloud database providing open source data management capabilities.

The cloud management manager 210 can easily manage the service through the log data and can grasp the flow of the cloud resource intuitively, so that the cloud management manager 210 can cope with the occurrence of the fault in advance.

A management tool located within the cloud management manager 210 is a RESTful application program interface for integrating with a management infrastructure of the cloud infrastructure so that large-scale virtualization environments can respond quickly to service requirements in a short period of time while minimizing administrator intervention. API).

In addition, the management tool not only facilitates operations such as addition and deletion of independent virtual nodes managed in the cloud stack, but also facilitates coping with various operating environments such as changing roles and extending roles of specific virtual nodes, And virtualization resources to monitor large-scale users and virtualization nodes so that they can always provide stable services.

These management tools can be provided in the form of packaged software that is installed and used on a desktop computer, and package software is installed on a specific desktop computer, unlike the web-based software, It can be used as a very restrictive approach through self-certification for network and verified users only.

The internal structure of the management tool is divided into a data area for managing data, a process area for processing commands, and an input / output area for managing input / output packets. The management tool communicates with servers, such as the cloud management server and the web server, physically separated to collect and display data on the screen. Therefore, inside the management tool, Http socket and DB socket are created to communicate with external server and data is exchanged.

In order to expand hardware resources, the cloud service processor 220 re-interprets resources connected to the network and divides them into logical units. The logical unit includes a zone, a pod, a cluster, a host Host).

To increase the reliability of cloud services, cloud infrastructure can be deployed in multiple geographical locations, or regions, and the region is composed of many zone nodes. A region is a useful unit in terms of fault tolerance and disaster recovery, placing the zones in adjacent physical locations.

Zone nodes are the largest set of units in the cloud stack and can be compared to a data center. Such a zone node can be connected to a plurality of zone nodes for interworking with a data center of another region locally, and consists of one or more pod nodes and an auxiliary storage 223.

When multiple zones are configured, it is possible to keep the cloud service uninterrupted by another zone node physically separated from any failure in a particular zone node.

A pod node is likened to one server rack and consists of at least one cluster node. Because you can use only the same subnet within the same pod node, you have to design it when considering multiple pod nodes.

Since secondary storage 223 can be shared between pod nodes, pods can be added to increase resources when considering expansion within the same zone node.

The secondary storage 223 can be connected to the host server 221, which is a host node, only in one of the network connection methods, NFS method. The main role is a template that is a file backed up in the ghost backup format at the time when the OS is installed and executed. It is used to store static data such as files in ISO format, snapshot (Snapshot), and is located in the zone node.

Since the auxiliary storage 223 can be constructed in at least one zone within the same zone node and the same is located in the zone node, all of the virtual machines created in the host node of the cluster node located in the corresponding zone node can be used.

The cluster node is composed of at least one host server 221 and a main storage 222. Only the same type of hypervisor can be used for the same cluster node, and there is a number supported by the cluster node depending on the type of the hypervisor. If you use XenSever as a hypervisor engine, you can add up to 8 limitations per cluster node.

The primary storage 222 is located in a cluster node and serves as a virtual hard disk of a virtual machine and can be connected to at least one or more than one. In contrast to the secondary storage 223, a network connection method It supports both iSCSI and NFS, and is related to the performance of the virtual machine because it serves as the hard disk of the virtual machine.

The host node refers to the host server 221. Since the host node 221 is located in the cluster node and provides a virtual machine, the performance of the host node greatly affects the virtual machine. When configuring a host node, host servers in the same cluster node must be configured with the same CPU family.

The host server 221 provides resources such as CPU, memory, storage, and network required to execute the virtual machine, connects a high-bandwidth TCP / IP network to the Internet through an internal connection, It exists in many data centers.

3, if the client terminal 110 registers as a member in a web site operated by the host device 200 and then logs in using the account information issued through membership registration, And transmits the signal to the host apparatus 200.

The host device 200 invokes the VM creation command to create a virtual machine of the specification selected by the user in the hypervisor engine in the cloud service processor 220 based on the VM usage application signal.

The cloud management server 211 selects a template stored in the secondary storage 223 according to the VM creation command call and allocates a virtual hard disk of the virtual machine to be newly created to the primary storage 222. [

The cloud management server 211 establishes the DNS through the public IP automatic allocation and the DNS automatic setting provided by the function server 300 and transmits the VM generation completion signal to the client terminal 110 after completing the VM generation.

Then, the client terminal 110 waits for 1 to 5 minutes and then receives the VM console, remote monitoring, FTP, web hosting, and cloud service through the newly created virtual machine.

FIG. 4 is a diagram illustrating an actual cloud service environment of a cloud-based web hosting system according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the cloud service environment in which the cloud-based web hosting system is actually installed has a basic structure required in the cloud stack, and the main storage 222, which serves as a virtual hard disk of the virtual machine, Because it has a great influence, the secondary storage 223 for connecting the network connection method type iSCSI method supported by the cloud stack and the backup data is connected by the NFS method.

The host server 221 connects four nodes in total and configures the same cluster node in the same pod node. The access of the cloud management server 211 does not restrict the use of the service by making it possible to access the management tool and the public network which can access only the private band for security enhancement.

5 is a view for explaining an API structure of a cloud stack according to an embodiment of the present invention.

Referring to FIG. 5, the management tool performs an authentication process in the Http communication according to the command protocol requested in the cloud stack to the first cloud management server 211. The command protocol is delivered as predefined contents in API (Application Program Interface) format. All commands are sent in response form requested by the management tool.

ServerUrl is a URL of a web service running on the basis of Tomcat where the cloud management server 211 is located. To use the API, the string / client / api? Is appended to the end of this URL. The Command item can be selected from APIs defined in the cloud stack. There are more than 100 APIs, including those related to authentication, including manipulating VMs and manipulating virtual nodes.

Data is input parameter value required by the API selected in Command item. ResponseType can select data format to receive response after API request. It can be selected from Xml and Json format.

ApiKey is a key value issued by authorizing the cloud management server 211 to request an API for each user account. Signature often plays a role of CRC (Cyclic Redundancy Check), which is a check value for checking whether there is an error in data transmitted when data is transmitted from a network, etc., and generates a signature according to an internally defined rule.
