  A fundamental ambition of grid and distributed systems is to be capable of
sustaining evolution and allowing for adaptability ((F. Losavio et al., 2002),
(S. Radhakrishnan, 2005)). Furthermore, as the complexity and sophistication of
theses structures increases, so does the need for adaptability of each
component. One of the primary benefits of service oriented architecture (SOA)
is the ability to compose applications, processes or more complex services from
other services which increases the capacity for adaptation. This document
proposes a novel infrastructure composition model that aims at increasing the
adaptability of the capabilities exposed through it by dynamically managing
their non functional requirements.
