According to the policy for "e-Korea construction" of Korean government, Investment of information system during the past decade are dramatically increasing. More than a half of this investment is cost of hardware infrastructure. So, accurate hardware sizing are essential for higher efficiency of investment. Accurate hardware sizing benefits are generally viewed in terms of the avoidance of excess equipment and lost opportunity costs by not being able to support business needs. Unfortunately, however, little research effort to make the hardware sizing methodology are doing. We propose a sizing method for information system in public sector. This method is determinate empirical study that are gathering and analyzing cases, making method and reviewing expert. Finally we are proposed calculating method for hardware components that is CPU, memory, internal and external disk according to the application system type which is OLTP, Web, WAS. Our study certainly will act as a catalyst for higher investment-efficiency of the future information programs in public sector.

Interest about Information infrastructure construction is enlarged socially according to arrival of information age, and various information systems are constructed for efficient business processing, customer service in public sector. According to subjective method for performance improvement for information system of public sector and engine that propel information system construction because it is no definite hardware sizing guidelines for information system caterer, is calculating resource volume of information system. It is situation that problem of excess of scale or reduce sizing is happening and is causing various kind of problems that is waste of information budget and service decline thereby. In this research, we proposed hardware sizing framework for information system that is applied to pubic sector.

In this study, It is suggested how to utilize hardware capacity sizing system for WEB, WAS, OLTP server's CPU, memory, and disk capacity by its user reasonably. To achieve goal of this study, we presented specific approaches in aspect of institutional viewpoint. The result of this study can be reflected gradually in the guideline of informatization related budgeting by MPB(Ministry of Planning and Budget) and e-government supporting program.

Estimating optimum hardware capacity of an e-learning system is very important process to grasp reasonable size of designing technique architecture and budget during step of ISP(information strategic planning) and development. It hugely influences cost and quality of the whole project. While investment on information system hardware has been continuously increased, there was no certified hardware capacity estimating method in e-learning system development. A guideline for hardware sizing of information systems was established by Telecommunication Technology Association in 2008. However, the guideline is not appropriate for estimating optimum hardware capacity of an e-learning system because it was designed to provide general standards for estimating hardware capacity of various types of projects. The purpose of this paper is to provide a methodology for estimating optimum hardware capacity in e-learning system development. To develop the methodology, this study, first of all, analyzes two e-learning development projects, in which the guideline was applied to estimate optimum hardware capacity. Then, this study finds out several key factors influencing on hardware capacity. Finally, this study suggests a methodology for estimating optimum hardware capacity of an e-learning system, in which weights for the factors are determined through AHP analysis.

Interest about information infrastructure construction is decayed socially according to arrival of information age, and various information systems is constructed for efficient business processing, customer service improvement in public sector. According to subjective method of performance improvement for information system of public sector and engine that propel information system construction bemuse it is no definite hardware sizing guidelines for introduction or system caterer, is calculating resources scale of information system. Is situation that problem of excess of scale or reduction sizing is happening, and is causing various kinds problem that is waste of information budget and service decline thereby. So, We proposed hardware sizing framework for information system that is applied to information programs.
