A white paper written by Don Kiely about one of the biggest buzzwords of this moment: SOA, Ruby on Rails is the other of course.

Here is an excerpt from the introduction: "The dominant client-server and n-tier application architectures of the 1990s ran into serious scalability and availability issues when used to implement massive Internet e-commerce sites. One of the major problems is that data tended to be stored in a massive, centralized database that all client components had direct access to. Virtually all communication with the database was in the form of SQL statements or batches of statements in a stored procedure, so that the client received a set of data for the specific task at hand.

Other problems arose when trying to incorporate “legacy” systems into newer applications. After decades of deploying a wide variety of systems using various proprietary technologies and platforms, the world was awash in systems that did their job perfectly well but had no clear path to interact with other applications in an increasingly connected environment. Achieving the agility needed by today’s applications has been extremely difficult. Business-to-business (B2B) interactions complicate things even further, requiring standard and reliable ways of conducting business electronically. Clearly, evolving systems that meet the needs of today’s global"
