A large number of technical architecture patterns support infrastructure and middleware
environments. For example, a proxy architectural pattern5 enables message interception, manipulation,
and enrichment. The originator of the SOA ESB-related pattern validate, enrich, transform,
and operate (VETRO),6 David Chappell, suggests processing intercepted messages before they
reach their destination (functionalities that are supported by ESB products). Furthermore, the pipes
and filters architectural pattern7 enables distributed systems to exchange processed filtered data
and information via a set of ???pipes??? that interconnect related systems. Moreover, other middleware
architectural patterns that support core products and enable dynamic and remote invocation
of services are of the ???publish and subscribe??? category. These enable searching and identification
of services over the network, and help consumers both to discover services and to identify their
offerings.
SEGMENTATION PERSPECTIVE. Among the most vital business model ingredients are the client
and market segments targeted by an organization. Although it may sound easy to identify, companies
recognize the need for commissioning research organizations to target market sectors and
classify customer preferences. ???To whom do we sell???? is a challenging question that calls for market
exploration efforts that lead to constructing marketing and client relationship support systems
driven by specialized technical architectures.
