How to Eat an SOA: Using Dynamic Composition to Build Composite Applications


Presentation by Matthew Adams


As SOAs become more and more prevalent, much of the focus among developers
and vendors has been on how to build services, but not so much on how to
consume them. In a realistic composite application, there is much more than
a web service or two that must be accessed; there are often multiple
services implemented in differing technologies, as well as multiple
databases, relational or otherwise. Dynamic composition makes building
composite applications easier by leveraging metadata about databases' and
services' behavior in order to calculate workflow at runtime, instead of
today's more common practice of doing so at design time. The benefits of
leveraging dynamic composition include the ability to pursue a truly
business level data and/or object model, much simpler transactional control,
and the ability to encapsulate but still directly communicate with the
underlying resources without introducing a message queue and the associated
development and message marshaling overhead. 

Xcalia will be giving away one Xcalia Intermediation Core (XIC) license at
our next meeting. 

XIC is a dynamic composition platform providing universal access to
service-oriented data sources, such as web services, EJB session beans,
legacy applications, and anything else callable from Java, as well as the
more traditional database-oriented data sources, such as relational
databases. Dynamic composition, exclusively from Xcalia, is a revolutionary,
new way to address the needs of composite application development within an
SOA, providing a transparent means to consume both service and database
resources in a way that reduces development effort and encapsulates the
composite application from the details of those various resources without
requiring the introduction of a message queue, business process execution
language (BPEL), or an enterprise service bus (ESB).
