In this paper we present an architecture and prototype implementation of an approach to providing such redundancy at low cost in service-based infrastructures. In particular we consider services that are supplied by composing a number of component services and consider how service discovery, automatic monitoring and failure detection have the potential to create composed services that are more dependable than might be possible using a straightforward approach. The work is still in its early stages and so far no evaluation of the approach has been carried out. JF - UK e-Science All Hands Meeting 2003, 2-4th September, Nottingham, UK CY - Nottingham, UK ER -
