Description

Remote sharing distributed processing system

The present invention utilizes remote sharing technology and distributed processing technology in the field of computer networks and application services, and more particularly, remote sharing technology of data storage media; And a load balancing technique for increasing processing capacity by utilizing a plurality of physical servers. And an information system construction and configuration method that combines distributed processing technology to enhance service stability and high availability to group a plurality of computers located in different physical regions into multiple groups to process the same service for each unit group, and It relates to a computer-readable recording medium recording the method.

With the rapid expansion and development of information and communication technology, the increase in the capacity and performance of personal (home) computers is accelerating every year, and the speed and quality of high-speed Internet networks including xDSL and optical communication are also increasing every year. Accordingly, the demand and necessity of using a personal computer as an application server instead of a client computer are also increasing.

To use a personal computer as a server, first obtain a fixed Internet Protocol (IP) address for connecting to the Internet via xDSL or cable network, or reboot the computer every time using Dynamic Domain Naming System (DNS) technology. When resetting the line, the DNS server must be notified of the dynamic IP address newly obtained from the ISP's system to prevent the request coming to the computer.

On the other hand, when only one personal computer is used as a server, there is a limit that the risk of service failure due to a sudden power off problem, an internet access line problem, a hardware failure problem, or a software failure problem is too high.

Even if you configure your server with two or more computers in the same space, you cannot reduce the risk of a stable electricity supply unless you introduce an uninterruptible power supply (UPS) at a separate cost. There is a problem.

In addition, since the processing capacity is limited per unit server, there is a risk of failing to provide a normal service and falling into a panic or incapable state when a request exceeding the processing capacity floods at a time.

In conclusion, when configuring and servicing a server using a personal (home) computer, there are a number of environmental factors, including instability and capacity limitations on the Internet line, computer hardware / software instability and capacity limitations, power supply and humidity and temperature. Due to instability problem, there is a limit in securing stability and processing capacity required for application service server in general.

The technical problem to be solved by the present invention is to solve the above problems, by combining a plurality of personal computers into a plurality of groups, data sharing between the computers in a unit group, load balancing of services and service distribution processing and QoS (Quality) dynamic group reestablishment based on service level, so that failures can be minimized probabilistically, thereby limiting the instability and capacity of individual computers on the Internet line; And computer hardware / software instability and capacity limitations; And to solve the instability problems due to various environmental factors, including power supply and humidity and temperature, and to ensure the service stability and high availability required for the application service server.
