  • 1. Fujitsus Approach to SaaS in Japan Fujitsu SaaS Platform Koji Satake(Manuscript received March 26, 2009)Software as a service (SaaS) and related services have appeared in recent years as an evolution of the application service provider scheme. SaaS enables corporate users to use services that are already being provided instead of constructing and owning business systems on their own. This has an immediate positive effect on business value such as reduced IT investment and new market development. The concept of Cloud computing, which makes use of new virtualization technologies, has also just emerged and an expansion toward Cloud services that encompass conventional data-center services and SaaS-related services is under way. This paper describes Fujitsus approach to SaaS business in Japan as a first step toward global expansion, focusing on a SaaS platform that will provide core service functions to support this transition from existing SaaS to future Cloud services. 1 Introduction when they are needed and to pay for only thoseThe mid-1990s saw the launching of theportions of services that are used, the concept of Internet for general users and the appearanceCloud computing has appeared as an approach of application service providers (ASPs), utility that provides extremely high scalability computing, and related services. Then, in(Figure 1). the mid-2000s, as the system infrastructure Against this background, the business environment ranging from terminals and environment is changing greatly.

Both customers deployment technologies such as Java, Ajax,and vendors are experiencing problems in and mashups evolved dramatically, the software securing the personnel required for planning, as a service (SaaS) concept appeared. The aimdeveloping, and operating systems as a result of, was to overcome the weak points of ASP and for example, a mismatch between the skill set improve the practical use of over-the-networkrequired for designing, developing, and operating services in business. In recent years, systemlegacy systems and that required for todays vendors have provided application executionopen source systems. Second, infrastructure platforms and services covering the range from and technology are changing dramatically in application to operation from their data centers the information technology (IT) environment. in addition to the traditional provision of system This is being manifested in the shift toward a infrastructure. Furthermore, as customersubiquitous society, the explosion in data, and the have expressed a desire to utilize services only consolidation of systems in data centers. AndFUJITSU Sci. Tech.
