Toward realization of service-oriented architecture (SOA)
Isao Morita · Fujitsu Scientific and Technical Journal · 2006
These days, companies must quickly identify changes that will affect them and quickly respond to those changes. In some cases, to secure global competitive superiority, companies must make rapid decisions to start new businesses as early as possible. On the other hand, because the IT systems at the heart of businesses are developed in response to individual requests, there are multiple platforms and application architectures, which causes complexity and bloating. This makes it hard to grasp the overall situation, making it difficult to adapt a system to a new business and ensure consistency when a system is maintained. Service-Oriented Architecture (SOA), which is a concept for making systems robust against change, is attracting attention as a way to solve these problems. Fujitsu made its system of SOA technologies public in July 2005 to facilitate the realization of IT systems that are robust against change. This system provides SOA development techniques (SDAS/Service Modeling). This paper describes the technologies used to realize SOA.
