Abstract
Abstract. Service-oriented computing (SOC) paradigm promotes the
idea of assembling application components into a network of loosely coupled
services. Web services are the most promising SOC-based technology.
A BPEL process definition represents a composite service that encapsulates
some complex business logic including the invocation to other
(external) web services. The complexity of a BPEL process together with
the invocation of external services subject to network and computer failures
requires countermeasures to tolerate this kind of failures. In this
paper we present an overview of FT-BPEL, a fault-tolerant implementation
of BPEL that copes both with failures of the machine running the
BPEL process and network failures in a transparent way, that is, after a
failure the system is able to resume the BPEL process consistently.
