“The components in an SCA composite application can run
on different nodes in a network. In Apache Tuscany, an SCA domain
can be used to administer a set of nodes. In SCA, the definitions
of composites, components, their implementations, and the nodes
they run on belong to what’s called an SCA domain. SCA
implementations like Tuscany provide administration tools that let
a system administrator manage the SCA artifacts in the domain.
Using the domain gives you the flexibility to specify installation
characteristics of nodes, such as host or port, at the time the
nodes are added to the domain instead of in composite files. This
article demonstrates how an application comprised of a number of
SCA components can be administered via an SCA domain. Learn each
step involved in adding an SCA application to the
domain.”
