A Service Component Architecture (SCA) domain consists of the definitions of composites, components, their implementations, and the nodes on which they run. Components deployed into a domain can directly wire to other components within the same domain. For the Feature Pack for SCA on a single server, the domain is essentially the scope of the server. For a multiple-server configuration, the domain is essentially the cell.
