Abstract (in Japanese) (See Japanese page) 
(in English) Wide use of information technology increases the importance of information system failure avoidance. It is a problem to make information systems integrated with open IT component more dependable under the pressure of lower prices. We address this problem by clarifying the basic framework of information systems reliability, surveying reliability technology which have been used in mainframes and open systems, and analyzing statistics and actual cases of recent information system failures. It is obtained that the reliability of open systems is becoming close to that of mainframes, that it is required to achive higher reliability and lower prices at the same time, and that it is necessary to level up the reliability including human operators and xSP services that have attracted less attention ever.
