Publication number: 20150178699Abstract: The necessity of calculating a SaaS usage fee by a SaaS service provider is eliminated, and operation efficiency of the SaaS service provider is improved. When a SaaS user 10 uses a SaaS 14, the used volume thereof is accumulated in an operation-system database 21 through a SaaS execution infrastructure 17. When a usage-fee calculation date of the SaaS 14 comes, a business infrastructure 18 acquires used-volume information from an operation infrastructure 19 and calculates a usage fee of the SaaS 14 in accordance with application contents of the SaaS user 10 and usage cost of the SaaS execution infrastructure 17, the business infrastructure 18, and the operation infrastructure 19 used by the SaaS service provider 12 for realizing the SaaS 14.Type: ApplicationFiled: September 26, 2012Publication date: June 25, 2015Inventors: Hiroshi Wada, Nobuyuki Yamagishi, Makoto Horiguchi, Akikazu Tanaka
