Byzantine Fault-Tolerant HTTP Services using FARGOS/VISTA

The FARGOS/VISTATM suite of technologies implements an infrastructure for the development, deployment and non-stop operation of transparently distributed, multithreaded, architecture-neutral, object-oriented peer-topeer applications. These capabilities can be applied in a variety of paradigms, ranging from simple client/server applications to more sophisticated applications that are dynamically loaded into to a pool of cooperating host systems, as well as fault-tolerant systems that eliminate single points of failure. With little effort, these capabilities can be exploited to provide conventional applications with unprecedented reliability. This is illustrated by the implementation of Byzantine faulttolerant transaction monitor for HTTP-based applications.
