We describe the design and implementation of SWORD, a scalable resource discovery service for
wide-area distributed systems. In contrast to previous systems, SWORD allows users to describe
desired resources as a topology of interconnected groups with required intragroup, intergroup, and
per-node characteristics, along with the utility that the application derives from specified ranges
of metric values. This design gives users the flexibility to find geographically distributed resources
for applications that are sensitive to both node and network characteristics, and allows the system
to rank acceptable configurations based on their quality for that application.
Rather than evaluating a single implementation of SWORD, we explore a variety of architec-
