Key Findings:

• Service-Oriented Integration (SOI) simplifies system integration by providing a single, simple architectural framework based on Web Services in which to build, deploy, and manage application functionality.
• The SOI market is expected to grow from $435 million in 2001 to about $6.2 billion in 2006.
• The top three EAI vendors have over 43% of the overall EAI market. With the entrance of Microsoft and other vendors in 2002, this landscape is expected to change.
• Web Services isn’t an integration technology, but a distributed computing technology that lends itself well to being used in integration scenarios.
• In a Web Services context, there really is no difference between EAI, B2Bi, and Data Integration.
• SOI solutions allow users to get a greater level of interaction and granularity with components deep within the application.
• SOI faces challenges in immature specifications, insufficient reliability, security, and transaction control.
• Microsoft and IBM have made strong entries into this space that will be a challenge for other providers of SOI solutions.
• The potential ROI realized by adopting Service-Oriented Architectures (SOA) far outweighs the slight benefits an organization gets from using Web Services as simply a “better API” for accessing application functionality.
• Integrating systems between two businesses is not only a technological problem; it requires pre-existing business relationships between the companies.
